Abstract

This work investigates the performance of Cs2CuSbCl6-based lead-free perovskite solar cells for photovoltaic applications. Cs2CuSbCl6 has a bandgap of 1.7eV and it is a durable and non-toxic material. Cs2CuSbCl6 can absorb more photons and thus obtain high efficiency. This work has been performed using SCAPS-1D software with the focus on optimizing the absorber layer thickness in terms of solar cell performance metrics such as efficiency (η), fill-factor (FF), open-circuit voltage (Voc), and short-circuit current density (Jsc). The highest efficiency of 21.67% has been obtained for the optimized value of the absorber layer thickness of 900 nm, with values of 1.22 V, 21.19 mA/cm², and 83.19% for Voc, Jsc, and FF respectively. Thus, Cs2CuSbCl6 -based solar cell paves as the safe alternative to lead-based solar cells for photovoltaic applications.

效率> 21.67%的无铅Cs2CuSbCl6钙钛矿太阳能电池性能评价

本文研究了用于光伏应用的cs2cusbcl6基无铅钙钛矿太阳能电池的性能。Cs2CuSbCl6具有1.7eV的带隙，是一种耐用无毒的材料。Cs2CuSbCl6可以吸收更多的光子，从而获得更高的效率。这项工作是使用SCAPS-1D软件进行的，重点是根据太阳能电池性能指标(如效率(η)、填充因子(FF)、开路电压(Voc)和短路电流密度(Jsc))优化吸收层厚度。当吸收层厚度为900 nm时，吸收效率最高，分别为1.22 V, 21.19 mA/cm2, Voc, Jsc和FF的效率分别为83.19%。因此，基于Cs2CuSbCl6的太阳能电池可以作为铅基太阳能电池的安全替代品用于光伏应用。
