Ferroelectric solar cells based on inorganic–organic hybrid perovskites

Abstract

Ferroelectric solar cells were fabricated by using the inorganic–organic hybrid perovskite materials, and power conversion efficieny as high as 6.7% had been obtained based on the MAPbI_3−xCl_xthin film. This work provides an alternative avenue for high-performance ferroelectric solar cells beyond inorganic ferroelectric oxides.
