Manufacturing High-Quality Crystalline CsPbBr3 Perovskite Photoactive Films in Open Air

Silicon, commonly used in solar cells, has low light absorption, rigidity, and high manufacturing costs. CsPbBr₃ inorganic metal halide perovskite films are solution-processable polycrystalline thin films with a higher bandgap (~2.3 eV), making them ideal for tandem applications. This project focuses on controlling the printing and crystallization process to optimize coverage and density for maximum light absorption. This research aims to create a better understanding of controlling CsPbBr3 crystal size and film thickness. The addition of poly methyl methacrylate (PMMA) and starch is studied to create effective photoactive perovskite solar cells.
