Abstract

A self-powered,solution-processed perovskite photodetector with sub-nanosecond response time is presented. Eliminating charge trapping and removing the constraints from the resistance-capacitance constant increases the response speed, which enables them to be applied in a homemade, time-resolved photoluminescence system that successfully resolves the decay process of typical fluorescence and phosphorescent materials with a recombination lifetime from several nanoseconds to microseconds.

Keywords: perovskite photodetectors; response speed; time-resolved photoluminescence lifetime; transient photocurrent.
