Abstract

Doping, introducing impurities in the materials, plays a critical role for junction formation in semiconductor. It directs the flow of charge carriers and improves their transport properties in the thin-film electronic devices including halide perovskite materials based optical-electric devices. Dopants can strongly modify electronic, optical and other properties of materials. Due to the relative smaller size, alkali metals play an important role for halide perovskite materials. In this review, recent research work on the doping of halide perovskite materials by alkali metals, especially the electrochemical doping, have been studied from the view of chemistry and physics.
