Perovskite is a crystalline organometal made mostly of calcium titanate, and is found in deposits all over the world. It was first discovered over 150 years ago, but only recently have scientists started investigating its use as a solar panel semiconductor replacement for silicon. It certainly makes sense if we can work out the kinks. Perovskite is considerably cheaper to obtain and process than silicon, and the light absorbing layer can be incredibly thin — about 1 micrometer at minimum versus at least 180 micrometers for silicon. That’s why the spray-on solar panel tech demonstrated by the University of Sheffield is plausible as a real-world solution. extremetech/extreme/187416-high-efficiency-spray-on-solar-power-tech-can-turn-any-surface-into-a-cheap-solar-cell https://facebook/AnonRev2
