Grain and Interface Engineering for High Efficiency Hybrid Perovskite Solar Cells

Abstract

The goal of this project is to overcome challenges regarding the fabrication of high-efficiency hybrid perovskite photovoltaic planar heterojunction (PHJ) devices using a low-temperature solution process. Challenges that will be addressed include the 1) presence of too many non-radiative charge recombination channels and 2) lack of proper charge transport layers in PHJ devices. Our approach to address these challenges is to form compact highly crystalline organometal trihalide perovskite films with a large grain aspect ratio by the interdiffusion of solution-deposited lead iodine and methylammonium halide stacking precursor layers, and modify the anode and cathode with functional charge transport layers to eliminate the charge recombination channels.
