    Rather than scraping the ITO off the glass, what about immersing the glass directly in a bath of hot oxalic acid, a bit like an etching tank? I guess that some chemicals from the glass might leach into solution, but as you said, leaving it for a few days will precipitate them out. Would that work without crushing the glass? (and save a heck of a lot of scraping...)

    Dang! I coulda had a sweet side business as a TV installer recovering indium tin oxide from all the broken LCD panels I had access to over the years, I did take apart a couple and kept some LED backlights and those focusing sheets - apparently you can construct an LED lighting panel that feels more like natural window light from the focusing sheets, which was my plan but I don’t really have the space to rework a 65” panel in my little place now - once I move it might be more of a possibility but harder to get ahold of expired TVs where I’ll be.

    I came for a short explanation for building a solar cell from a LCD screen. There's alot of info in here that's valuable but if you're only here for the explanation of making one, It's very short and you will need to find a video on it. Timestamp: 8:36

    I have been trying to get those 2 pieces of glass apart. I have not been successful. Do you have any tips on doing that? I really want to make a solar cell.

    Hi, wondering what can you do with those acids after such processes? Is there a way to neutralize them? I'd love to recover ITO but only if I can do it without pollution.

    ok so if i make a solar cell out of the screen you were working on about how many watts would it produce before i use Fresnels and mirrors?

    RMS - light on silicon - could you do a perpetual battery flashlight? ie, putting the .5V through a few caps and a small dc/dc converter? could have the mossfet either outside or open the cone collector in the light itself
