Metal Halide Perovskites for Next-Generation LED and Transistor Applications

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Although metal halide perovskites are very promising for use in solar cells, other applications using perovskites are possible. In Kyushu University, we obtained a four-fold increase in external quantum efficiency of perovskite LEDs by choosing appropriate organic cations for the incorporation into perovskite structures. We showed that perovskites can work as the excellent host or transport layers of organic LEDs. We demonstrated hole and electron mobilities of up to 26 and 4.6 cm2 V-1 s-1 in solution-processed perovskite field-effect transistors. Our transistors fabricated by the lamination with perovskite single crystals revealed hole and electron mobilities ranging from 50 to 100 cm2 V-1 s-1, along with excellent stability even in air.
