The purpose of the article was to explore diy manufacturing of pv cells. I don't think this korean/swiss collaboration on high efficiency perovskite solar cells

  Perovskite cell manufacturing is quite DIYable. There's been several experiments (lab-scale, not industry-scale) with making the lead-based perovskite film from waste with very minimal equipment. The main problem is toxicity, both to people handling it and to environment if disposed of improperly. Example: https://www.youtube.com/watch?v=oQ2bz6jlbz0 https://www.youtube.com/watch?v=oQ2bz6jlbz0

  The purpose of the article is mental masturbation. The intro motivates the topic by noting that silicon solar cells present a toxic environmental hazard. The author then, apparently with a straight face, posits that cells made from antimony or selenium, of all things, would be a good alternative. For more laughs, the author goes on to suggest that one of advantages of such antimony and selenium cells is that you could build them without a protective covering—-that the semiconductor would be fully exposed to any passerby. It’s like those renfair cosplayers who reject electric motors for their zombie apocalypse scenarios, and plan to repopulate the earth using hydraulic machinery with “easy to procure from any junkyard” flexible hydraulic hoses.
