A highly photoconductive composite prepared by incorporating polyoxometalate into perovskite for photodetection application

Abstract

A photoconductive perovskite–polyoxometalate composite was prepared for the first time by a facile low-temperature and solution-processed method, and this composite exhibited a significantly enhanced photoconductivity and photodetection performance due to introduction of polyoxometalate into the perovskite for fine energy-level matching and efficient charge transfer.
