Cheaper-Than-Silicon Solar Cell Materials

DailyTech - Scientists Find Nine Cheaper-Than-Silicon Solar Cell Materials

Iron pyrite is the top material picked by a University of California at Berkley and Lawrence Berkeley National Laboratory to replace silicon in solar cells. While modestly less efficient than crystalline silicon, its dramatic cheaper in processing costs and very abundant. Adopting it as a replacement to silicon or thin films could dramatically cut costs and enable enough production to supply the world's power needs, according to the team. (Source: Crystals Guide
