In this paper, we physically modeled a bifacial perovskite/PERT-silicon tandem solar cells for the first time using Silvaco technology computer-aided design simulator (TCAD). The cell model was calibrated with the reported experimental data of perovskite solar cell (PSC) and PERT-silicon solar cell. The effects of perovskite thickness (t_pvk) and perovskite bandgap were investigated on the performance of bifacial tandem solar cells under different albedo. The simulation results predict that the optimum t_pvk increases with albedo intensities because a thicker perovskite layer is needed to facilitate current matching for high albedos. Moreover, the t_pvk tolerance for a high-efficiency bifacial tandem solar cell increases with albedo. The simulation results reveal an efficiency over 31.9% for 0.45–1 μm of t_pvk with 1.65–1.75 eV perovskite bandgap for a bifacial tandem cell under 30% albedo. Additionally, compared to the monofacial cell, the tandem design shows an enhancement of about 30% at the spectral albedo level of common grounds like concrete. The simulation and analysis presented in this work can help optimize perovskite/silicon tandem cell manufacturing to achieve higher power conversion efficiencies.

在本文中，我们首次使用 Silvaco 技术计算机辅助设计模拟器 (TCAD) 对双面钙钛矿/PERT 硅串联太阳能电池进行了物理建模。电池模型使用钙钛矿太阳能电池（PSC）和PERT-硅太阳能电池的报告实验数据进行校准。研究了钙钛矿厚度（t _pvk）和钙钛矿带隙对不同反照率下双面串联太阳能电池性能的影响。模拟结果预测最佳t _pvk随着反照率强度增加，因为需要更厚的钙钛矿层来促进高反照率的电流匹配。此外，t _pvk对高效双面串联太阳能电池的耐受性随着反照率的增加而增加。模拟结果显示，对于30% 反照率下的双面串联电池，0.45-1 μm t _pvk的效率超过 31.9%，具有 1.65-1.75 eV 钙钛矿带隙。此外，与单面电池相比，串联设计在混凝土等常见地面的光谱反照率水平上显示出约 30% 的增强。这项工作中提出的模拟和分析有助于优化钙钛矿/硅串联电池的制造，以实现更高的功率转换效率。
