Influence of MAPBI3 Annealing Temperature on Perovskite Solar Cell

Abstract

This study mainly is carried out to discuss the effect of nitrogen annealing temperature on perovskite solar cells. The annealing temperature affects perovskite solar cells during the annealing process. It also affects the formation of perovskite crystals. Perovskite crystals need to form in a nitrogen box for manufacturing Perovskite solar cells. Spin-coating MAPbI3 on the substrate is annealed with a nitrogen furnace tube to form perovskite crystals. The remaining PbI2 after the annealing is completed to improve the efficiency of perovskite solar cells. The optimal temperature for the formation of perovskite crystals is found by adjusting the annealing temperature. By using UV-visible spectrometer, field emission-scanning electron microscope, and measurements of photoelectric conversion efficiency, cell structure and optoelectronic properties are analyzed as the final results.
