Abstract

Perovskite materials have garnered significant attention in the photovoltaic sector, particularly in solar cell applications, primarily due to their exceptional physical and chemical properties. These include a high light absorption coefficient, tunable bandgap width, long charge carrier diffusion lengths, high carrier mobility, and the capability for solution processing. These attributes make perovskites a strong candidate for creating high-efficiency and low-cost photovoltaic devices. This article improves the light absorption capacity of Cs₃Bi₂I₉ single-crystal perovskites through optical simulation, utilizing the unique properties of photonic crystals to enhance the photovoltaic effect. The article concludes, based on simulation results, that the photonic crystal structure significantly impacts the absorption spectrum of Cs₃Bi₂I₉ thin film samples, offering benefits for solar cells, photodetectors, and related applications.
