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.
