Abstract

Polyvinylidene difluoride (PVDF)‐based perovskite solar cells (PSCs) have led to continuous improvements in efficiency of up to 24.23%. These types of polarization‐enhanced solar cells offer a simpler strategy to achieve stable polarization to increase efficiency. The fundamental research progress in polarization‐enhanced built‐in fields in PVDF‐based PSCs is reviewed. Herein, it is discussed how polarization can be induced by piezo‐phototronic effect and spontaneous and external electric field poling. Finally, the directions for high‐efficiency PSCs based on PVDF are outlined.
