Another post from atomicmonkeyI posted about this a few weeks ago to little fanfare but I think it is worth revisiting. Perovskite solar cells are touted to be the next best thing in solar technology due to their efficiency in converting sunlight to electricity and their potential for flexible and lightweight designs. Perovskite is also poised to be included in the next generation of high clarity displays such as QD tv's. Cesium is an integral part of Perovskite's makeup. Here is an article titled "The resource demands of multi-terawatt-scale perovskite tandem photovoltaics" . The article is a comprehensive analysis of the material demands and potential supply criticalities for scaling up perovskite photovoltaic (PV) technologies. Cesium is given a huge spotlight. I took the liberty of passing this onto the info email of PWM as I'm sure Hayden is lost without my guidance, lol. Here is the cliff notes of the article relating to cesium from AI and the link to the full article. Adding.
