lead‐free perovskitesphotodetectorsthermal stabilitySolution‐processed metal halide perovskites (MHPs) have demonstrated great advances on achieving high‐performance photodetectors. However, the intrinsic material instability and the toxicity of lead still hinder the practical applications of MHPs‐based ...
The toxicity issue of lead-based halide perovskites hinders theirs large-scale commercial applications in solar cells. A variety of non- or low-toxic perovskite materials have been used for development of environmentally friendly lead-free perovskite solar cells, some of which show excellent optoelectro...
double perovskiteslead-freeThe double perovskite family, A2MIMIIIX6, is a promising route to overcome the lead toxicity issue confronting the current photovoltaic (PV) standout, CH3NH3PbI3. Given the generally large indirect band gap within most known double perovskites, band-gap engineering ...
Solution-processed metal-halide perovskites are emerging as one of the most promising materials for displays, lighting and energy generation. Currently, the best-performing perovskite optoelectronic devices are based on lead halides and the lead toxicity
Metal halide perovskites have outstanding emission properties2,3; however, the best-performing materials of this type contain lead and have unsatisfactory stability. Here we report a lead-free double perovskite that exhibits efficient and stable white-light emission via self-trapped excitons that ...
