Electrical characteristics of CsPbI3 and CsPbBr3 lead halide Pervoskvite nanocrystal films deposited on Si-c solar cells for high-efficiency photovoltaics

The high performance of hybrid solar cells based on nanoparticles to improve optical and electrical performance is the subject of many current studies. For this purpose, nanoparticles of perovskite CsPbI₃ and CsPbBr₃ are used as their optical properties have provided good interaction with crystalline silicon (Si-c), the absorption coefficient (α) is significantly high in different ranges which increases the generation of photocurrent in the range 370-900nm. The degradation quickly reduces the efficiency and for specific results, developed equipment is reguired. CsPbI₃ has shown a textured surface while CsPbBr₃ surface is smooth, according to this better measurement for iodine content became possible.
