Major advance in solar cells made from cheap, easy-to-use perovskite

more »
Physicists have boosted the efficiency of material that holds promise as base for next-generation solar cells. Perovskite solar cells are made of a mix of organic molecules and inorganic elements that together capture light and convert it into electricity, just like today's more common silicon-based solar cells. Perovskite photovoltaic devices, however, can be made more easily and cheaply than silicon and on a flexible rather than rigid substrate.
