Abstract

Solar cells fabricated by piezoelectric semiconductor materials, such as GaN, AlN, and CdS, enable better performance due to piezo-phototronic modulation. Recent experiments have revealed the possibility to further improve the energy conversion efficiency of perovskite solar cells with a gallium nit...
