Abstract

The efficiency of perovskite solar cells is studied through the Analysis of Microelectronic and Photonic Structures (AMPS) and the Solar Cell Capacitance Simulator (SCAPS) simulation software programs. The programs serve to determine how the thickness of HTM, ETM and perovskite absorber layers affects the performance of solar cells. An investigation is also conducted on how temperature, electron density concentration and perovskite defect density affect the fill factor (FF), performance (PCE), short-circuit current density (J_SC), and open-circuit voltage (V_OC). Then, J–V characteristics are calculated using ZnO and SnO₂ as two types of ETM. As a result, optimal values are achieved for the thickness of HTM, ETM and absorber layers. It is also indicated that an increase in the defect density of perovskites can reduce the performance of solar cells. Another important finding of the study is that ZnO can possibly replace the expensive SnO₂ for better ETM conversion performance.

SnO 2和ZnO对钙钛矿太阳能电池性能的影响

抽象的

通过微电子和光子结构分析（AMPS）和太阳能电池电容模拟器（SCAPS）仿真软件程序研究了钙钛矿型太阳能电池的效率。该程序用于确定HTM，ETM和钙钛矿吸收层的厚度如何影响太阳能电池的性能。还对温度，电子密度浓度和钙钛矿缺陷密度如何影响填充系数（FF），性能（PCE），短路电流密度（J _SC）和开路电压（V _OC）进行了研究。然后，使用ZnO和SnO ₂计算出J – V特性作为两种ETM。结果，HTM，ETM和吸收层的厚度达到了最佳值。还表明钙钛矿缺陷密度的增加会降低太阳能电池的性能。该研究的另一个重要发现是，ZnO可以替代昂贵的SnO ₂以获得更好的ETM转换性能。
