Perovskite materials could make a splash in light emission as well as solar power generation, according to researchers at Tokyo Tech who have engineered associated charge transport layers to achieved a significant performance boost. The result is a green ∼500,000cd/m2 33 lm/W perovskite (CsPbBr3) LED,  a 20,000cd/m2 CsPbBrI2 red LEd and a CsPbBrCl2 blue one. The same CsPbBr3 green perovskite ...
