Solution processing of perovskite thin films

Chinese researchers offer a simple route to bandgap engineering Lead-halide perovskite solar cells are one of the hottest topics in materials science. And for good reason – in less than a decade, their conversion efficiency has grown from 3.8 % to over 20 %, bringing them into the range of more traditional solar photovoltaic materials. But their reliance on...
