In recent years, perovskite-based solar cell technologies have sparked much interest. Organic-inorganic halide perovskites (OIHPs) are a type of perovskite that has shown promise in various optoelectronic applications. The power conversion efficiency (PCE) of organic-inorganic perovskite materials is improving with new materials development. However, inorganic materials studied in labs have limited PCE. Lead-free tin halide CHNHSnX shows good PCE. In this work, we study the electrical characteristics of tin halide as a perovskite absorbing layer in planar heterojunction solar cells with the help of GPVDM solar cell simulation software. A comparative study of power conversion efficiency has been done for tin halide of chloride, bromide, and iodide. The effect of electron and hole drift-diffusion, carrier continuity equations in position space to represent charge flow within the device, Poisson's equation, and charge carrier recombination has been studied in detail.
近年来，钙钛矿基太阳能电池技术引起了广泛关注。有机-无机卤化物钙钛矿（OIHPs）是一种在各种光电应用中表现出前景的钙钛矿。通过新材料的开发，有机-无机钙钛矿材料的功率转换效率（PCE）正在提高。然而，实验室中研究的无机材料的 PCE 有限。无铅锡卤化物 CHNHSnX 表现出良好的 PCE。在这项工作中，我们使用 GPVDM 太阳能电池模拟软件研究了平面异质结太阳能电池中锡卤化物作为钙钛矿吸收层的电特性。我们对氯化物、溴化物和碘化物的锡卤化物进行了功率转换效率的比较研究。详细研究了电子和空穴漂移-扩散、位置空间中的载流子连续性方程以表示器件内的电荷流动、泊松方程和载流子复合的影响。
