As polish citizen and enthusiasts of physics I am extremely proud of your achievement. I'm looking at it right now in the store in United States. Exact application pricing labels! It will be wonderful if this product was exclusively made in Poland only! Imagine what kind of world white success for you, and for entire country of Poland, will that be!
They just started printing panels in Wrocław - Polska. Panels are already available for selected companies and manufacturing is ramping up as we speak.
Very exciting technology. Thank you for sharing your expertise and making a significant contribution to the dissemination of knowledge in this field of Perovskites solar cells.
I was surprised to find solar cells using perovskite were being made around a decade ago! Some interesting videos on YT showing how these cells were originally made. Imagine if this had top engineers and scientist working on this back then, where we could be now!
Amazing presentation from Olga @TEDx Talks.👏🏾 Funny enough, I'm also researching on perovskites for my bachelors degree final year project at University. The possible applications of this technology are exciting, to say the least. Just thinking, perhaps this is what the ancient Egyptians might have put on the pyramids at Gyza, if they were actually built as power plants, we never know.🤷♂️
O Great ! Olga, The energy spent is the energy gained equally. Thank you for bringing this technology out to world, Your simple way of explanations!!!!
I had heard of perovskite, but was not familiar with this new technology, Olga Malinkiewicz described in this presentation. The ink jet application, of cheap perovskite, to cheap plastic foil substrate, will bring the cost down dramatically, bringing affordable solar power to many new applications, and affordable for millions more people, around the world. This young lady has made remarkable progress. Her hard work and perseverance, have brought the world closer, to a carbon neutral sustainable society. This will be especially important, in rural areas of poor countries, which are now largely ignored, increasing the quality of life for millions of people worldwide. Today there are over 2 billion people who lack access to safe pure drinking water, free of pollutants and diseases. Affordable solar power will make it possible to distill and remove toxic pollutants and harmful pathogens, which cause so much suffering and death today, especially of infants and children.
Toxicity depends on the elements used to make the perovskites. If Lead (Pb) is usedthen toxicity is an issue. If Pb-free perovskites are used, toxicity is never an issue.
A lot of challenges for perovskite solar cell other than toxicity, that significantly affects its BoS (Balance of System] practically. Even lead-free perovskites have their several issues .....But yes admittedly Lead-free is one option to make it nontoxic.. Due to the other major problem, Perovskite solar cells unable to reach at customers' end. and commercialization road map still needs a lot to do on perovskites. Hopefully, the scientific community definitely solve this ahead. Thank u so much for the discussion.
Absolutely awesome! I can imagine a civilization with this on all buildings, & inside of offices where light will be shining on anyways, this is a form an Electric energy Recycling. Brilliant 💡☀️😃
Olga good luck with your plants Produce those cells in millions and show doubters that Polish women can do it. Do not let the big corps crush you. All the best , improve your English and go BIG!!!!
The only issue is its susceptibility to humidity and its reliability. Of course if we sort these two issues out not only the chargers we can throw out everything else as well. But those outstanding issues might take a few more years.
Great idea. Great presentation! Powodzenia Olga!! Trzymam kciuki, żeby ta technologia rozprzestrzeniła się jak dziki pożar. Oczywiście z Saule Technologies w centrum :)
The perovskite quantum crystalline cell structure is part of the solution, but three nanoparticles are also needed to produce femions for energy production. I will admit that I still understand little of the hypothetical prototype system, as the complexities are eminence.
some chines company are making devices that are being tested for almost 2 years and showing promising results, but I agree a long way to go but short way compared to development of other technology( consider the energy payback time)
Exciting new technology, but she is only talking about the possible applications! What about time to market, pricing etc?? Applications will be developed if the product hits the market. That's the easy part!
Batteries must become obsolete, capacitors will replace them. Capacitors charge instantly, they are working on the technology of slowly releasing the energy as needed.
Szukam kontaktu do Olgi ,moze ktos jest w stanie mi pomoc ? Sprawa strikte biznesowa ,pracuje nad startupem zwiazanym z ta technologia ! Z gory dziekuje !
9:15 Those are some veeeeery simple calculations. Way too simple, I'd say. Direct sunlight near equator can give up to 1 kW of power per square meter. That gives 7,6 Watt for her Iphone size. Current top consumer panels have 25-30% efficiency at best. That gives us at best around 2.3 Watt, which is barely enough to start charging any modern phone. But wait. We don't live near equator, right? So, our Sun irradiation is even less. And we won't bother directing our phone perpendicular to Sun, right? So, we get even less light. Also, there is not always a midday, sometimes is cloudy, and shadows may occur. And there's also need to convert panel voltage into phone compatible voltage, hence more losses. In reality, you'll be lucky to consistenly get at least one watt from sun in real conditions, not in your fantasies. And don't even start to talk about light indoors, it's laughable. Light intensity indoors is in orders of magnitude less than under sunlight.
It’s a start. This talk was literally spitballing ideas with tech that exists. Damn son. You are just a pessimistic little dude. We have to start somewhere, and her breakthrough is more than you’ll ever do, so why not just sit back and let the adults take care of the future Mk? Thankssssss
@@seacaptain72 Not sure I understand your point. My calculations show that there's no possible way her ideas are ever giong to succeed in our real world. At least on the topic of putting solar panel on back of our phones. Do you agree? If you disagree, then what are your arguments?
agreed. They are way too many obstacles in implementation of perovskite. She forget to mention the hygrophobic nature of perovskite which since starting has always been the main obstacle. Yet, i still believe this material will still able to be commercialize someday ..
@@DimaZheludko I am quite sure she is acutely aware of all the limitations, as well as the barriers of entry. This is an expert in her field. As far as disagreeing with experts in their fields, that's not something I really do, unless I can stand my ground and have published or made significant contributions to the work. Too many times, I watch people do some back of the hand calculation, and call it solid. Y'all basically wanna use ideal gas law for any sort of fluid, and things just don't work like that. Her ideas may not work, I'll grant you that. What's important, is that she's trying something. The most unlikely ideas don't always work, but sometimes they do. And for anyone to be putting down something that seems like it could work, especially in the face of extinction? What exactly are you doing to help? Where's your great idea, and all the arduous research that it requires to be tested? Anything is better than nothing, and she's trying.
Is that good? She said 1 minute in the sun equals 1 minute of phon3e use. I charge my phone for 1hr 20m and get 5.5 hours constant use, 4:1 . Turn playback speed down to .75 if you want to understand her.
Yes it's good. You're thinking immediate usage, not dead time charging. I spend a lot of time at a desk with my phone just sitting there doing nothing. With this all that dead time of it just sitting there becomes charge time. Probably have to top it up at night, sure. But this would get me through a day. The really interesting thing about perovskites though isn't that. It's the spectrum of light it uses to create electricity. It's a different wavelength than silicon uses. What that means is we can dope silicon with a perovskites layer for solar sells using an ink jet printer and just under double their efficiency. Perovskites pull energy from one part of the spectrum, the rest of the light goes through and hits the silicon and it makes electricity from it's part of the spectrum. That isn't theoretical btw. Labs have been doing it for a few years. They've just been trying to figure out how to ramp it up to volume production. The really cool thing though, perovskites are cheap to manufacture compared to silicon. Almost double the efficiency for 10-15% extra manufacturing cost. Again, that isn't theoretical, that's been built and tested. Solar arrays can suddenly be half the size or create double the electricity. That's the real use case of perovskites. Her use case is interesting for a limited set of consumer electronics, not most. And no-one is going to coat a building with them when it a more efficient use of resources to build a large solar array of silicon and perovskites outside of town. The building will pay off the solar array first, but the one outside of town is so much more efficient it's going to catch up and pass the building fast. Both hers and the combination solar cells are 5 years from commercial production and 10 years from volume production. But once it does, everything else is going to go out of business. Solar is already not too far off from everything else at cost per watt, not there, but not too far off. This makes it cheaper at cost per watt than everything else.
Idea is nice but when we talk about practicality of scaling it on large number then there comes a major factor of pricing which is also holding electric vehicle back. So what about pricing....🤔🤔
I work with Perovskites, they are really cheap, the most expensive part is the Hole Transport Layer (HTL), but even so it's cheaper than traditional solar panels, they are lightweight, tunable and even more efficient than some solar panels on the market, for further cost reduction it's just needed the economy of scale that comes with time and the learning curve. Perovskite Solar Cells are really a great breakthrough, the only problem right now (and we're working on it) it's the stability, moisture and oxygen can damage the material but it's getting more and more stable daily and soon it will get even more stable than silicon. The possibilities go way beyond what Olga have exposed, we can make Tandem Solar panels, Perovskite over Silicon, where each of it will absorb some part of the light spectrum and make traditional solar panels even more efficient, we can make Perovskite nanocrystals that can work as photocatalysts for all kind of chemical synthesis, it's possible to use the Perovskites as LEDs (they emit light too) and can use for cathode materials for batteries, we're in the beginning of a Perovskite Revolution, if you have any doubts I would be happy to answer
@@iphigenia8661 I can't give you an exact number, unfortunately. Now I'm trying to find some passivator that can protect the Perovskite Absorber Layer from moisture, oxygen and from ionic flux and at the same time help the charge separation and conduction to the electrodes, if we can find this passivator, in theory the Perovskite would last as long as the passivator, we can even use other approaches like self healing, the Perovskite crystals have self healing properties too that we can use to heal defects where moisture and oxygen can react and destroy the structure. There are even other possibilities like encapsulation of the cell, hydrophobic charge extraction layers, surface engineering, photon down-conversion layers,alters the dimensionality of the cell from 3D to 2D or even 1D, this makes the cell even more stable because of the energies involved in the structure of the material ,change in composition ABX3 to get more strong bonds that will increase material stability (formamidinium cells have greater stability than methylammonium ones because of the hydrogen bonds are stronger), so there are infinite possibilities that we can try, and use this material not only in for optoelectronic applications but as sensors or smart windows (the perovskite goes an phase change in certai temperatures), use the electron-hole pair generation in for photoelectrocatalysis in CO2 reduction (synthetic fuel),organic synthesis (pharmaceuticals and polymers), hydrogen generation, light production using quantum confinement effects for LEDs, with 2D perovskite we can storage ions for cathodes in lithium ion batteries and we can blend the Perovskite with other materials to get other properties like piezoelectricity, thermoelectricity (seebeck effect) and so on
Come on, this is a PV device, you still need the same battery and still need the same battery charger, you just changed the source of electricity. When do this generation stop pretending that everything they do radically change the world?
A lot of unprofessional talk, but no mentioning of the most important issue, what is the conversion percentage of light of your methods, is it 20%, 30% or maybe as your talk imply, it's 60% or more. Efficiency is measured in these cases as conversion percentage and you should know that as scientist. Talking big without mentioning mere FACTS shows that you're more into business and raising money rather than science.
@@millenniumzeekNot really. $/KWh is affected by efficiency. Since there are only limited ways to increase the energy density of sunrays (e.g. using reflectors), a larger surface area is required to compensate for the lower efficiency.
Only fantasies, no real facts. Efficiency? Cost for mass production? Panel voltage and output current? At least anything of substance, please! You don't need to name me every single thing where you could put this new panel. Just tell me how it's better than what we have now and I'll tell you myself what to do with it. All useful information in this video takes less words than my comment.
The aim of this talk was to raise awareness of the technology. All useful information you are asking can be googled in less time, then it was to write that comment. Wikipedia: Solar cell efficiencies of devices using these materials have increased from 3.8% in 2009[4] to 25.2% in 2020 in single-junction architectures,[5] and, in silicon-based tandem cells, to 29.1%,[5] exceeding the maximum efficiency achieved in single-junction silicon solar cells. Perovskite solar cells are therefore currently the fastest-advancing solar technology.[2] With the potential of achieving even higher efficiencies and very low production costs, perovskite solar cells have become commercially attractive.
@@FischiPiSti My poit was that you don't raise awareness of *real* technology by spreading your basic (and probably false) fantasies. One thing I expect from expert in the field is at least some field-specific info. Not the basic "you can put our new solar cell on anything that requires power" thing. What's even worse, she spreads some dubious claims about phone charging indoors. That just shows how out of touch from real engeneering she is, which makes things even worse. Modern lights may take about 20 to 50 watts to light entire room, not just a tiny patch of 78 square cm.
@@w0ttheh3ll I don't need *that* much of a detail. I need at least something of substance. She's informing of or advocating for perovskites solar panels, right? So, what is the most obvious question one might ask? The most obvious, I stress that. - We already have a few solar panel types, why we need another one type? Unless she answers how these new cells are better than existing ones, she sounds like used cars salesman.
You can stop arguing now. Info on perovskites is all over the place. So no need to dog on a little Ted talk. Instead of trying to dominate discussions. I suggest that you use your energy to go change the world. But, your choice.
bad idea with that " music " intro ...it discourages people from watching further because it sounds like a chip mediocrity commercial . It is a mediocre entrance while perovskite solar panels are genius and revolutionary .. Why do good things have to be ruined by idiots who don't know about class and go follow " pod publiczke " ? Why couldn't be the music of Chopin or high class Polish Jazz ??.
Good idea but terrible presentation. NO science content and no real numbers! Need to project more confidence. I am sure that you can do a lot better. Do NOT give up. Just keep going. You are on the right track but there are a lots of twist and turns along the way. Good luck (you need that too). :-)

It's a fairly old technology BTW gaining traction these days due to enhanced material science.
“Just changing the source of electricity “ is HUGE for most of the world. Plus, if this works out, you ALSO detach from reliance on “the grid.”

Efficiency becomes less important when looking at $/KWh
@@millenniumzeekNot really. $/KWh is affected by efficiency. Since there are only limited ways to increase the energy density of sunrays (e.g. using reflectors), a larger surface area is required to compensate for the lower efficiency.
Supposedly Tandem Perovskite thin film solar cells should be able to reach 30% efficiency, tandem perovskite+Si are pretty much already there.

Disturbing entrance ... They were singing her name ? Anyways, the whole thing is cringing if you are a practicing professiinal engineer
Packs of Edisons are waiting to either get it in their copying hands ;) or do everything to discredit the technology. Heads Up!
@Chris Kiehart Interesting angle.
Only fantasies, no real facts. Efficiency? Cost for mass production? Panel voltage and output current? At least anything of substance, please!
You don't need to name me every single thing where you could put this new panel. Just tell me how it's better than what we have now and I'll tell you myself what to do with it.
All useful information in this video takes less words than my comment.
The aim of this talk was to raise awareness of the technology. All useful information you are asking can be googled in less time, then it was to write that comment.
Wikipedia: Solar cell efficiencies of devices using these materials have increased from 3.8% in 2009[4] to 25.2% in 2020 in single-junction architectures,[5] and, in silicon-based tandem cells, to 29.1%,[5] exceeding the maximum efficiency achieved in single-junction silicon solar cells. Perovskite solar cells are therefore currently the fastest-advancing solar technology.[2] With the potential of achieving even higher efficiencies and very low production costs, perovskite solar cells have become commercially attractive.
@@FischiPiSti My poit was that you don't raise awareness of *real* technology by spreading your basic (and probably false) fantasies. One thing I expect from expert in the field is at least some field-specific info. Not the basic "you can put our new solar cell on anything that requires power" thing.
What's even worse, she spreads some dubious claims about phone charging indoors. That just shows how out of touch from real engeneering she is, which makes things even worse. Modern lights may take about 20 to 50 watts to light entire room, not just a tiny patch of 78 square cm.
she did mention 10% efficiency several times. if you want that much detail, a TED talk is the wrong medium. go read a research paper.
@@w0ttheh3ll I don't need *that* much of a detail. I need at least something of substance. She's informing of or advocating for perovskites solar panels, right? So, what is the most obvious question one might ask? The most obvious, I stress that.
- We already have a few solar panel types, why we need another one type?
Unless she answers how these new cells are better than existing ones, she sounds like used cars salesman.
You can stop arguing now. Info on perovskites is all over the place. So no need to dog on a little Ted talk. Instead of trying to dominate discussions. I suggest that you use your energy to go change the world. But, your choice.
bad idea with that " music " intro ...it discourages people from watching further because it sounds like a chip mediocrity commercial .
It is a mediocre entrance while perovskite solar panels are genius and revolutionary .. Why do good things have to be ruined by idiots who don't know about class and go follow " pod publiczke " ? Why couldn't be the music of Chopin or high class Polish Jazz ??.
She also made a statement with her pants...
O ja piedziele ale sie ubrala haahha
Good idea but terrible presentation. NO science content and no real numbers! Need to project more confidence.
I am sure that you can do a lot better. Do NOT give up. Just keep going. You are on the right track but there are a lots of twist and turns along the way. Good luck (you need that too). :-)
What a BS
Presentation :( ... Idea .... !!!!!! :)
Plastic is distroy by sun 😆😆😆
booring, not subject... your talk is
