It’s a Diy tutorial to make Solar cell. Cuprous oxide is a semiconductor, just like doped silicon, and was one of the first materials experimented with as a solar cell. But its efficiency was found to be so low, around 1%, that researchers stopped trying, though the occasional set of experiments are still done in research labs and papers published. It was also used to make commercially sold diodes and may still be, since that’s what a solar cell is – a photosensitive diode.
