I remember some old book mentioning that you can make one more easily by heating a copper sheet and then putting the traces on with "silvering solution"(so probably conductive ink).

Can, or could you use algae growing for your backyard swimming pool in place of the zinc oxide? assuming you concentrated it from green water into something more slimy(er)

Thank you for your useful demo and for the efforts you have taken to teach us. Thanks from Jawaharlal Bharath India 🙏

True DIY genius!

Total newbie to this stuff, but if the zinc Oxide is a thermoelectric material and the heat from the light is doing more than the light itself, would it make since to use a darker protective coating over the ZO to attract more light wavelengths and therefore more heat?

Historically, sticker paper has sometimes been used as etch resist itself. I once got a PCB fabrication kit that came with etch resist stickers for traces and components. Maybe try removing the other part of the sticker paper, pressing the remaining part down really good, and then skipping the marker. If the sticker paper does work well as resist, you'll get much better etching results than with marker. That will save you a step and all of the time spent trying to get the marker lines thick enough _and_ get you a better end result!

Look up "dye activated solar cells". If I recall correctly, they also use zinc oxide but apply a dye afterward to increase light absorption, increasing efficiency and thus current.
