Perovskite materials have become a hot topic in the field of optoelectronics due to their unique optical and electrical properties,such as high carrier mobility,high photoluminescence efficiency,high extinction coefficient,adjustable band gap,etc.However,most perovskite materials contain lead,and the toxicity of lead has hindered the large scale industrial application of perovskite optoelectronic devices to a certain extent.To break through this limitation,lead in perovskites can be replaced by less toxic chemical elements such as tin,bismuth and antimony.In this paper,the research progress of the material properties of lead free perovskites and their applications in solar cells,photodetectors,light emitting diodes and other optoelectronic devices are reviewed,and the future development in this direction has prospected.
