Light can improve perovskite solar cell performance
(WorldNews Switzerland)

27.04.17- Publishing in Nature, EPFL scientists show how light affects perovskite film formation in solar cells, which is a critical factor in using them for cost-effective and energy-efficient photovoltaics. Perovskites are materials of immense interest in solar energy technology lately, as they promise to bring down the cost of solar cells to very low levels. Their efficiency heavily depends on our ability to control their deposition into films, but the factors that influence the synthesis of perovskites are not well understood. EPFL scientists have now shown that, in the two most common methods used today, light can greatly accelerate the formation of perovskite films and control the...
