And in wind turbines (for the same reason). What about solar panels? Maybe not the cheaper ones?

- pjc50 6y agoConventional monocrystalline or polycrystalline panels do not use rare elements. Slightly fuzzy diagram: https://www.researchgate.net/figure/Structure-of-monocrystalline-solar-cell_fig1_320345931 https://www.researchgate.net/figure/Structure-of-monocrystal... Cadmium-telluride and CIGS cells use more rare elements, but they have been overtaken by the ongoing fall in cost of conventional silicon wafer cells, so you won't see too many of them being installed at the moment. (The failure of CdTe is probably for the best given how spectacularly poisonous both of those metals are)
