Abstract

Tandem solar cells offer a wider photon absorption range, enabling greater efficiency compared to single junction counterparts. The upper cell efficiently captures high-

energyphotons

, while the lower

filtered through the top layer. Achieving efficient, cost-effective, and durable solar cells requires the integration of absorber layers with optimal band gaps. This study presents a computational exploration of tandem

perovskitesolarcellsusingSCAPS - 1 D s i m u l a t i o n s

to improve device performance. The proposed dual-layer configuration features a top cell composed of ITO/ZnSe/CsPbI₃ and a bottom cell of ITO/ZnSe/CsSnI₃. The thickness of the perovskite CsPbI₃ layer in the top cell was optimized for peak performance, maximizing light absorption and enhancing charge carrier dynamics. Emission spectra from the first cell were utilized to guide the SCAPS-1D simulations for the second cell. The results reveal a notable

fillfactor (F F)

and an impressive

powerconversionefficiency (P C E)

of 29.38%, underscoring the superiority of this tandem configuration over single-junction designs. These findings demonstrate the potential of tandem perovskite solar cells to drive next-generation photovoltaic technologies, fostering advancements in

下一代太阳能：揭示CsPbI3/CsSnI3串联电池的前景

串联太阳能电池提供更宽的光子吸收范围，与单结太阳能电池相比，具有更高的效率。上层细胞有效地捕获高能量光子，而下层细胞吸收低能量光子通过顶层过滤。实现高效、经济、耐用的太阳能电池需要集成具有最佳带隙的吸收层。本研究提出了串联钙钛矿太阳能电池使用scaps - 1dsimulation来提高器件性能的计算探索。所提出的双层结构的特点是，顶部电池由ITO/ZnSe/CsPbI3组成，底部电池由ITO/ZnSe/CsSnI3组成。顶部电池中钙钛矿CsPbI3层的厚度优化了峰值性能，最大化了光吸收并增强了载流子动力学。利用第一个电池的发射光谱来指导第二个电池的SCAPS-1D模拟。结果显示了显著的填充系数（FF）和令人印象深刻的29.38%的功率转换效率（PCE），强调了这种串联结构相对于单结设计的优越性。这些发现证明了串联钙钛矿太阳能电池在推动下一代光伏技术方面的潜力，促进了高效、经济的太阳能解决方案的发展。
