Modeling of photoelectric characteristics and development of structures for solar cells based on CsPbI3 and CsPbBr3

Subject of study. Solar cells based on CsPbI 3 and CsPbBr 3 photosensitive inorganic perovskites are investigated. Aim of study. The study aimed to simulate and fabricate inorganic perovskite solar cells based on CsPbI 3 and CsPbBr 3 . Method. A theoretical study was conducted using the open-source AFORS-HET program, which is designed for one-dimensional modeling of solar cells and other optoelectronic devices. During the fabrication of the structures, various equipment, including an EZ4 spin coater for thin film and photoresist deposition, ULAB US-1500D heated laboratory magnetic stirrers, and a vacuum thermal deposition station, was employed. Main results. Solar cells based on CsPbI 3 and CsPbBr 3 photosensitive inorganic perovskites were simulated using the AFORS-HET software. The primary photovoltaic cell parameters, including the fill factor, short-circuit current, open-circuit voltage, and efficiency, were estimated. A theoretical analysis was performed to identify the factors and defects in the perovskite films affecting the solar cells’ performance. Based on the simulation results, photosensitive structures using CsPbI 3 were fabricated and characterized. Practical significance. The studied solar cells based on CsPbI 3 and CsPbBr 3 exhibit potential as efficient solar-to-electrical energy converters.
