Perovskite thin film: Out with the old, in with the new

While silicon-perovskite tandem solar requires optimization of both approaches, and embodies the weaknesses of each, using pure thin-film devices offers a cheaper, simpler, and more sustainable PV solution for the United States. High conversion efficiency, abundant-material composition, and lower cost of manufacturing make perovskites a potential game changer for the solar industry so what is the best path to commercialization? There has been a strong focus in the United States, and in the media, on perovskite-silicon tandem devices due to their potential to boost the efficiency of traditional ...
