I discovered this channel a few years ago while researching for my science fair project, on making my own solar cells. It’s pretty cool to see the new breakthroughs on the things that I researched about, using free articles online.
As someone who works in the solar industry, perovskites are very interesting (as is graphene conductors). Anything that may increase the efficiency of solar panels and their electricity generation is going to be good for the renewable future. I wonder if you’ve ever looked into inverter efficiency because converting DC to usable AC power (and in a safe way) is also a hurdle for solar electricity. Thanks for another great video.
@@thomasbonse why do you have to be so hard on cold fusion. It's trying really hard. Just another 30 years and they might have it. If you don't believe me, ask me again in 30 years and I'll give you the same answer.
@@Mike__B they are making massive steps forwards in relation to graphene, the production costs have been cut drastically and they can now manufacture it in large quantities at decent prices. So now the next step is graphene sheets but graphene in small portions are already being used in the UK in road construction with asphalt and concrete and seems to be showing very impressive results but I suppose it still needs to pass the test of time.
What do you want to look into regarding inverter efficiency? Microinverters are commonly 90% efficient and modern high frequency string inverters that are currently on the market are 95%+ efficient. There's no point in chasing the last 1 or 2% possible of efficiency since it'd likely make products more complicated, expensive, and/or shorter lived.
Love your stuff! So hard to be scientific and still hold the attention of the rest of us. Very informational and interesting. Keep up the good stuff while dummying it down without loosing either us or the information.
2:44 _"They created a perovskite film with a plasmonic substrate made of hyperbolic metamaterial and characterized it with transition dipole orientation."_ Language like that is opaque for most of us. I appreciate this channel demystifying it.
Great episode. I appreciate the breadth of your research, and how you present a topic with integrity rather than trafficking solely in hype and clicks. I mean, you clearly put in the work, and it shows. Cheers!
1000 hours to 95%. It's just 4 months (8h/day). Silicon based panels keep that for 10 years and the best ones for 20. So you're still a 30* factor behind. The problem is also the labor to change panels. You have to be really really cheaper if your lifespan is shorter or the cost to do the change more often will absorb that gain.
They didn't have time to test more yet, they only concluded that is still holding 95% in 1000 hours, but they will need months more to check if it can, for instance, reach 10k hours over lets say 90% and so on. Its a new tech, you can't expect them to have it tested for decades even on advanced wear facilities
@@MrCaiobrz You expect linear or less degradation? But it could be even worse. It could snowball and be exponentially bad... Anyway, even with the most optimistic case, it's still an order of magnitude behind silicon. Concerning the advertised value, it's not because they didn't have the time, it's because they want to give a good number that can be easily remembered. 95% and 1000h looks good for the average Joe but it's actually not much.
I'm super excited for this because I'm looking to put solar panels on top of a bus and in that case size matters way more than lifespan because I don't have very much room so having more efficient solar panels even if they don't last quite as long is acceptable especially if they're cheaper
I can never be a sleeper agent watching your videos. I always open my eyes and watch what your talking about and miss out on sleep. Your videos are pre bed time after work
I really appreciate this video. For those of us who don’t live down at or near Boca Chica, we count on those that do to give us the insight to what’s going on & the vibe. We get a lot of launch site or build site videos, but rarely ever get videos covering the village. I would also love it if someone would go around and interview residence that live in Brownsville, SPI, & Port Isabel and talk about how they feel about what’s happening down there. You know, give us the “Vibe” on what they think about how SpaceX is affecting the local region. Thanks Jessica, keep up your great work
I’ve been watching you for years. Love how you describe the information your presenting. You took something I really wasn’t interested in and drew me in. Thank you. Sleeper agent activated. 😂 10:03
Thanks for the comment. Not every advance is going to be a winner, but it's worth keeping an eye on everything that's happening. There's a lot of interesting work out there.
I miss the old discovery channel shows. But you are filling that void. So I honestly do thank you and ask you to please don’t stop making them. I do ask one thing. Lead, is detrimental to the environment you say. But the environment is what created lead. It’s a organic element on the periodic table. Just don’t eat it. And I use organic from the much older version of the Websters dictionary. Like 1950’s Meaning from the Earth, I truly thank you again and your videos are very educational and factual and I like that.
Thank you for your time and intelligence. You lay out the information very good, you don't put your spin on it to sway there view of the facts. I would like to thank you and will pass your page on to others
Thanks! Would be interested in more discussions between you and the technical leads at the various commercial companies to learn more about their upcoming products. Any mention of life time for the stuff coming out in 2023/2024?
Great job following up on the most current technologies for solar production. Hope you continue to update us on the comercial availability of perovskite panels.
You, like many, seem to be obsessed with perovskites. Yes, cheaper is a very good thing, and their efficiency is good too. Lifespan MUST be addressed before they can compete with silicon. Still... my personal favorite PV concept is the rectenna. These seem to have a long lifespan and potential for efficiency that other PV technologies can't even dream about. As with all technologies, the limiting factors are: first, making it work and second, manufacturing. An update on today's state of the art of the rectenna would be nice.
“O” boy Matt, finally, you may remember I got you to report on Perovskite years ago. It’s taken long enough. It’s ok, I needed time to learn to say it correctly. Thank you for that. Nice to see you again. How’s the new house ? Now maybe I can soon start designing bldgs with solar in the bldg structure. 👍✌️
The thing in your video that astonished me is that there is no international standards for measuring performance (if I understood you correctly) - I worked for a year or so at the National Institute for Biological Standards and Controls (NIBSC) in the UK and a major part of their job was agreeing (at the time with the US CDC) on international standards for diseases. They also produced samples of international standard quality diseases and exported them to researchers around the world. The purpose being that if Professor Singh in Bombay was working on a Hepatitis A treatment he could publish his work and it's efficacy could be directly compared with the results achieved by Professor Smith at Harvard, or Schulz at Heidelberg - and be easily replicated by other scientists verifying Singh's research. I mean we've only been looking at PV systems since the 60's - you'd have thought someone could agree on something by now.
For the most part, I've enjoyed watching your videos. However, one of the biggest issues with the corporate world is their love of the all mighty dollar. It has slowed down advancements more than anything else.
Thanks for this, Matt. We live on our boat, so we depend on our solar panels, but we need pretty robust ones. These developments are certainly interesting, & I'll be keeping my eye on the industry. But besides needing reliability, I have a lot invested in controllers & such. I get the feeling we're still 10 years out here...
Great video. I think the most important thing is the balance between longevity and effect per square meter/feet. Everyone talks about more powerful solar panels, but mostly they are just bigger. I do like however, that new technologies such as the one talked about in this video will potentially increase the effect per square meter/feet. Keep up the good work Matt. :)
Hmmm. The first 4 advances still look like they're in the research stage, or 5 years away from commercialization (and is often the case, 5 years from now, the prediction will be "5 years away"). Furthermore, each seem to address specific issues with perovskites, but don't look like they can be combined to address all issues. For number 5, Matt addresses the elephant in the room, which is how long before anything shows up on the market. But there is no indication of what compromises these first generation products will be making (performance, cost, toxic production methods, etc.), or whether the target markets will be broad or niche. To progress from research to engineering to mass production is incredibly complex and challenging. It makes you appreciate successes in technology even more.
This content is really very deep...i did 2 courses but i never get this type of content...please also make videos on current research opportunities and on some conpanies...it will help student to grab some opportunity
Another good one Matt, the numbers with efficiency seem to be a bit over the top with respect to 11:48 ? Can't wait for an update on your new house Matt.
Solar panels with 22% efficiency at converting light into electricity are NOT efficient. 78 of the sunlight is not converted into electricity The amount of inefficiency is far greater than the efficiency. Ergo, it is inefficient.
@@suryakisku3895 solar panels are actually the cheapest thing in the solar power system. during noon time, I even have to cover the panels to avoid excessive heat and extra power to avoid overcharging my off-grid system. my solar panels are only about $20 per 100 watts.
I think the "diffusion-stability-hysterisis nexus" from their actual paper title sounds like _way_ better Star Trek techno babble than "ionic desire path" 😊
This is a good video, but you're still missing the main reason that perovskites are being researched: depending on the materials used, they can have a variable band gap. The theoretical maximum efficiency of any single band gap cell is ~33%, but as the number of junctions approaches infinity, the theoretical maximum efficiency rises to ~87% (en.wikipedia.org/wiki/Multi-junction_solar_cell). This is (one reason) why the early cells are all perovskite on silicon; More junctions, more efficiency.
Sometimes efficiency is approached from the wrong side. Instead of wasting time to make solar cells more efficient, how about we make the manufacturing and recyclablity more efficient and greener? You know? Perfect first what we have? This has been in R & D already for so long, and what do we have? Silver and lead. More mining and toxicity. Lovely. Bravo...
Great video, i love the good information, but you totally forgot CIGS techonology. My bet is that CIGS will be the future within the next 1-7 years as they get cheaper to produce.
Hi Matt, Oxford PV has been announcing commercially available perovskite PV by 2020, then 2021, 2022,… Any chance of a video showing what keeps delaying Oxford PV and commercial manufacturing of perovskite PV over the last 3+ years?
Just some input as to why the liquid process might be difficult to scale. Thin films of liquid are typically applied to a surface through use of a spin coater. They spin at incredibly high speed and so only the liquid close to the surface can actually stay on the wafer. This means that for an 8” wafer it’s not that big of a deal. But a three foot solar panel that’s a ton of centripetal acceleration for the material to cope with.
No no. The production is done with single wafers and dried and then the contacts added and the module assembled. the process just becomes faster when a slot dye coater is used butthe efficiency drops alittle.
Could you make a video about the current highest efficiency solar cells like multijunction cells and also about promising high efficiency PV cells chemistries, like gallium arsenide, graphene multijunction, etc ?
I thought the other advantage to Perovskite cell was that they could extract energy from multiple em frequencies including UV light that cuts through clouds allowing for electric generation even on cloudy days.
it is the same with Graphene; discovered in 2004; was told it's a revolution material! Where is it used? Will it ever be used? Thanks for another great informative video
Watching your videos, I find myself thinking about whether or not any of these companies can be invested in. As a result, I’m thinking of two things that would be super cool if you can include them. First, if a company is publicly traded, it would be nice if you put in the Chiron, the company, stock symbol and trading platform, for example, NYSE, and then the stock symbol. The other thing you could do either in addition to, or instead, is have a list of all the companies that you do stories on along with links to their company profiles. Just a thought, and a reminder that investing in companies can be one way to encourage them to succeed. It also gives us an opportunity. If they’re probably traded to influence the choices, they make both in the products that they choose to make, but also in their labor practices and executive governance. That can have an impact on how Green and how responsible these companies are.
It should really be on UA-cam and the websites to simply make algorithms that search for patterns in comments from accounts and patterns in new accounts I mean they follow the same pattern over and over and over again and even whenever they do change their patterns they'll follow that pattern for a while and then the alchemists catch on to it and then auto block all of them and have a human look at them to verify
@Matt - thanks an awful lot for this one, this is exceptional news. I'd be curious to know how these things go in space too... As for terrestrial use - I'd love to see this type of thing implemented more frequently in suburbia especially now we have more people working from home (in the UK something like 50% or more of government workers are WFH'ing apparently). In hotter and sunnier areas where aircon will be used - this is going to be essential, especially for grid distribution and load management.
Deciduous Trees bring out their own SOLAR PANELS every spring. Then discards them when the ☀️ sun begins to diminish. Where their solar panels become a renewables resource. Food for the Tree. It's a beautiful thing ❤ GOT THE GUARDIO. 😊 Thanks. And Thank You for all the wonderful info you bring. By the way... Are there worth while investment opportunities available out there ?
Been following about half a dozen companies. About this this year. Looks like the military will need some highly effective solar cells for their half electric tank.
If anyone is confused like me that there are no elements called E and A: the PEA in PEA₂Zn₄ stands for the organic compound phenylethylammonium (C₆H₅CH₂CH₂NH₃⁺) and contains not only no hitherto unknown elements but also zero phosphorus 😄
This is one of the challenges and promises for solar. Currently the cost and uncertainty of utility credits is hampering more solar - add the possibility of major breakthroughs and I am sitting on the sidelines waiting for the future.
Great video, they are always interesting and lead me to wanting to know more. In fact your first perovskite video was the inspiration for an undergrad research paper I wrote on the topic so thank-you for the inspiration and keep up the great work.
So, long ago, BATTERIES were the study. How to make batteries last longer. When the hole time it was how to make the light bulbs more energy efficient. Welcome to the LED world. Now lights last forever. Hope the solor can actually become better than what it is currently.

Solar panel salesman: “yeah, we’re coming around just doing some free estimates. Blah blah blah.”
Me: “sorry, blub. I’m waiting for perovskites.”
lifespan & efficiency the key. we are 5+ years away from being able to buy anything with any real advancement over todays best panels.
Just some input as to why the liquid process might be difficult to scale. Thin films of liquid are typically applied to a surface through use of a spin coater. They spin at incredibly high speed and so only the liquid close to the surface can actually stay on the wafer. This means that for an 8” wafer it’s not that big of a deal. But a three foot solar panel that’s a ton of centripetal acceleration for the material to cope with.
No no. The production is done with single wafers and dried and then the contacts added and the module assembled. the process just becomes faster when a slot dye coater is used butthe efficiency drops alittle.
Keep it up, soon we’ll have the creative solar generator
Could you make a video about the current highest efficiency solar cells like multijunction cells and also about promising high efficiency PV cells chemistries, like gallium arsenide, graphene multijunction, etc ?
You've missed mentioning Saule Technologies that opened its manufacturing plant in 2021.
Exciting!
I actually read a paper on this a while ago. I hope that the adoption perovskites isn't hampered by greed.
I thought the other advantage to Perovskite cell was that they could extract energy from multiple em frequencies including UV light that cuts through clouds allowing for electric generation even on cloudy days.
I'm glad to hear they're improving solar cells. Maybe 1 day we can use solar power to travel
it is the same with Graphene; discovered in 2004; was told it's a revolution material! Where is it used? Will it ever be used? Thanks for another great informative video
Is it on the market? Mentioned possible to be buyable by the end of 2023. Would be cool.
Watching your videos, I find myself thinking about whether or not any of these companies can be invested in. As a result, I’m thinking of two things that would be super cool if you can include them.
First, if a company is publicly traded, it would be nice if you put in the Chiron, the company, stock symbol and trading platform, for example, NYSE, and then the stock symbol.
The other thing you could do either in addition to, or instead, is have a list of all the companies that you do stories on along with links to their company profiles.
Just a thought, and a reminder that investing in companies can be one way to encourage them to succeed. It also gives us an opportunity. If they’re probably traded to influence the choices, they make both in the products that they choose to make, but also in their labor practices and executive governance. That can have an impact on how Green and how responsible these companies are.
I hope you'll be visit Intersolar one of renewable energy exhibitions see new designs innovation by the companies on solar.
It should really be on UA-cam and the websites to simply make algorithms that search for patterns in comments from accounts and patterns in new accounts I mean they follow the same pattern over and over and over again and even whenever they do change their patterns they'll follow that pattern for a while and then the alchemists catch on to it and then auto block all of them and have a human look at them to verify
Thanks for dropping the knowledge! Are there any public companies that are focusing on using Perovskites? Would love to research and invest.
Very informative 👍
I've been pondering the combination of this with graphene for some time due the the structure
@Matt - thanks an awful lot for this one, this is exceptional news. I'd be curious to know how these things go in space too... As for terrestrial use - I'd love to see this type of thing implemented more frequently in suburbia especially now we have more people working from home (in the UK something like 50% or more of government workers are WFH'ing apparently). In hotter and sunnier areas where aircon will be used - this is going to be essential, especially for grid distribution and load management.
Great video, as always... but I think you said "Sly dot" instead of "Slot die" at 13:07. ;-)
Interesting video as always 👍
Great to see progress in thise solar cells too.
Thanks for sharing your thoughts with all of us 👍 😀
Thanks for watching!
Its nice to have hope.
Seems like we're sitting down and just having a think 😉
Perovskites will be great to power the air con at the fusion reactors coming in the next 10 years.
Deciduous Trees bring out their own SOLAR PANELS every spring.
Then discards them when the ☀️ sun begins to diminish.
Where their solar panels become a renewables resource.
Food for the Tree.
It's a beautiful thing ❤
GOT THE GUARDIO. 😊
Thanks.
And Thank You for all the wonderful info you bring.
By the way...
Are there worth while investment opportunities available out there ?
Could you cover sulphur based batteries at some point? They seem like a really promising advancement in battery tech.
they are briefly covered in other recentish battery vids i think
Been following about half a dozen companies. About this this year.
Looks like the military will need some highly effective solar cells for their half electric tank.
If anyone is confused like me that there are no elements called E and A: the PEA in PEA₂Zn₄ stands for the organic compound phenylethylammonium (C₆H₅CH₂CH₂NH₃⁺) and contains not only no hitherto unknown elements but also zero phosphorus 😄
Rochester is my home town too, but that was back before sunlight which was just after dirt.
You are quite an odd dude, but your channel is absolutely brilliant and awesome! Love every episode.
I'll take it 😜
in the future could you link to the articles or abstracts, plz. Great info thanks!
This is one of the challenges and promises for solar. Currently the cost and uncertainty of utility credits is hampering more solar - add the possibility of major breakthroughs and I am sitting on the sidelines waiting for the future.
Great video, they are always interesting and lead me to wanting to know more. In fact your first perovskite video was the inspiration for an undergrad research paper I wrote on the topic so thank-you for the inspiration and keep up the great work.
1000 hours? Wow! that is like 40 years. Those will last you a lifetime.
So, long ago, BATTERIES were the study. How to make batteries last longer. When the hole time it was how to make the light bulbs more energy efficient. Welcome to the LED world. Now lights last forever. Hope the solor can actually become better than what it is currently.
Forgot to mention Saule Technologies who is already producing ink-jet printed perovskites commercially.
I saw this video on s2t UA-cam channel in Hindi
