Abstract

Copper Indium Gallium Sulfide Selenide (CIGSSe)-based solar cells, featuring Al/ZnO/ZnMnO/CIGSSe/Cu₂O/Ni layers, are optimized using the solar cell capacitance simulator (SCAPS) for enhanced photovoltaic (PV) performance. The solar cell design incorporates a CIGSSe absorber layer, a zinc manganese oxide (ZnMnO) buffer layer, and a zinc oxide (ZnO) window layer. The upper/top and back contacts are made of aluminum (Al) and nickel (Ni), respectively, with an electron-reflected-hole transport layer (ER-HTL) of cuprous oxide (Cu₂O). The performance of the proposed structure can be improved by adjusting the thicknesses of the absorber, buffer, and window layers, along with the acceptor and donor concentrations of the absorber and buffer layers, series and shunt resistance, and temperature. The configuration improves the cell structure’s open-circuit voltage (V_OC), short-circuit current (J_SC), fill factor (FF), and power conversion efficiency (PCE). For optimal outcomes, set the acceptor and donor concentrations in the absorber and buffer layers to 10¹⁷ and 10¹⁸ cm^–3, respectively. Furthermore, keep the thicknesses of the absorber layer at 2000 nm, the window and buffer layers at 50 nm, and the ER-HTL at 10 nm. The optimized model demonstrates PV performance characteristics of 1.0642 V for V_OC, 36.10 mA/cm² for J_SC, 81.06% for FF, and 31.15% for PCE under the AM1.5G spectrum. Furthermore, it exhibits a quantum efficiency of around 95.23% at visible wavelengths.

不同层对提高 Al/ZnO/ZnMnO/CIGSSe/Cu2O/Ni 太阳能电池光伏性能的影响

摘要利用太阳能电池电容模拟器（SCAPS）对以铝/氧化锌/氧化锌锰/CIGSSe/Cu2O/Ni 层为特征的硒化铜铟镓（CIGSSe）太阳能电池进行了优化，以提高其光伏（PV）性能。太阳能电池设计包含一个 CIGSSe 吸收层、一个氧化锰锌（ZnMnO）缓冲层和一个氧化锌（ZnO）窗口层。上触点/顶触点和背触点分别由铝（Al）和镍（Ni）制成，电子反射空穴传输层（ER-HTL）由氧化亚铜（Cu2O）制成。通过调整吸收层、缓冲层和窗口层的厚度，以及吸收层和缓冲层的受体和供体浓度、串联和并联电阻以及温度，可以改善所建议结构的性能。这种配置可提高电池结构的开路电压 (VOC)、短路电流 (JSC)、填充因子 (FF) 和功率转换效率 (PCE)。为了达到最佳效果，吸收层和缓冲层中的受体和供体浓度应分别设置为 1017 和 1018 cm-3。此外，吸收层的厚度保持在 2000 纳米，窗口层和缓冲层的厚度保持在 50 纳米，ER-HTL 的厚度保持在 10 纳米。优化模型在 AM1.5G 频谱下的光伏性能特性为：VOC 为 1.0642 V，JSC 为 36.10 mA/cm2，FF 为 81.06%，PCE 为 31.15%。此外，它在可见光波长下的量子效率约为 95.23%。
