I think you're mistaken about how LEDs work. AFAIK, LEDs operate in the forward direction, which is why the voltage drop across them is only 2-3 volts. You can force diodes, especially Zener diodes, to conduct in the reverse mode, but that's an unrelated phenomenon. Again, as far as I know; it's been a couple of decades since my last active devices course.
Thank you, you are right, this needed to be corrected. Incorrect material was removed. I checked on the polarity of the LED N-type and P-type and that seems to be correct, so I won't kill the whole video. The electron current source is connected to the N-type (electron rich, not hole rich) side of the LED. So I got that right. But I got the operation of a standard diode wrong. You are right - the LED is forward biased not reverse biased.
This got me thinking I should paint a plastic sheet with some high-glow phosophorescent paint and see how far i get when it's charged under uv light 🤔 It also feels like there might be a project here for an old tablet-screen back-light.
Hello Peter I would like to ask you a question, the idea of using sodium polyacrylate to make something similar to an osmotic membrane has been on my mind for a long time, do you know of any solvent to dissolve it??? thank you, greetings, good job
I think sodium polyacrylate dissolves in water pretty well. I tried to impregnate a high quality filter paper with sodium polyacrylate to make a membrane but it didn't work especially well. I also tried to co-polymerize sodium acrylate with acrylamide and bis-acrylamide to make a poly-ionic hydrogel at one point. That seemed to work, but didn't make a particularly great battery separator membrane from what I can recall.
That is a great explanation of why light is emitted from a diode! I have a much better understanding of how they work now.
Thanks!

Great video, thanks for posting it!
I love El panels. But what do you do with the annoying sound coming out the Inverter?
Headphones? Kidding - It is an irritating buzz. The one I have is quiet enough that it doesn't bother me too much.
