Abstract

Perovskite solar cells (PSCs) are a favorable option for the upcoming generation of photovoltaic systems due to their simplicity and high energy conversion efficiency. The third iteration of thin-film solar cells including copper-tin-sulphide (CTS) is easily accessible on Earth, possesses excellent optoelectrical properties, and does not include any harmful substances, making it environmentally sustainable. Using the solar cell capacitance simulator (SCAPS), this study examines the performance of a PSC based on copper oxide (Cu2O) and zinc selenide (ZnSe). The study investigates the factors that influence the performance of CTS-based SCs, such as absorber layer thickness, absorber defect density, interface defect densities, doping densities, and working temperature on the performance of the PSC. The results show that 30.37 % perovskite cell efficiency (PCE) increased from 20.94 % after optimization with 0.9403 V of open circuit voltage, 37.2682 mA/cm² of short circuit current and 86.67 % of fill factor.

基于 SCAPS-1D 的无机硫化铜锡 (CTS) 包光体太阳能电池的数值建模和性能研究

过氧化物太阳能电池（PSCs）因其结构简单、能量转换效率高而成为新一代光伏系统的有利选择。包括硫化铜锡（CTS）在内的第三代薄膜太阳能电池在地球上很容易获得，具有出色的光电特性，并且不含任何有害物质，因此具有环境可持续性。本研究利用太阳能电池电容模拟器（SCAPS），对基于氧化铜（Cu2O）和硒化锌（ZnSe）的 PSC 性能进行了研究。研究调查了影响基于 CTS 的 SC 性能的因素，如吸收层厚度、吸收缺陷密度、界面缺陷密度、掺杂密度和工作温度对 PSC 性能的影响。结果表明，在开路电压为 0.9403 V、短路电流为 37.2682 mA/cm2 和填充因子为 86.67% 的条件下，过氧化物电池效率（PCE）从优化后的 20.94% 提高到了 30.37%。
