Don’t think that you can take this PDF How to Build Your Own Solar Cell and cheaply power your home. This is a chemistry project to explain how it works.
That being said, it is pretty cool to dye glass with berry juice and get measurable electric current from something you did yourself. I think this is a great weekend project with your kids. Or even something to do for YouTube. However, as I said earlier, it is not practical at scale.
Especially since this seems to be part of a kit. You need special glass to make this work. At the time I got this PDF I had not tried to see if I could contact the inventor to see the availability of the kit components.
I figure that this pdf gives enough information that a motivated individual could figure out how to get a kit. Or, to recreate it in they truly wanted to learn how to build their own solar cell.
While I have my fair share of solar cells and solar power is a part of my disaster and retirement plans. I feel reducing the need for electricity in general as well as using water for heating and cooking directly is more efficient.
