This work explores the development of hybrid perovskite solar cells using silver-gold chalcogenide (AgAuSe) as the substrate. The focus is on combining wide-bandgap chalcogenide ETLs like WS, SnS, and CeO with HTL CFTS. Three device configurations were analyzed: Device I (Al/FTO/WS/AgAuSe/CFTS/Au), Device II (Al/FTO/SnS/AgAuSe/CFTS/Au), and Device III (Al/FTO/CeO/AgAuSe/CFTS/Au). The study considered key factors influencing device performance, including doping concentration, layer thickness, absorber defect density, and the characteristics of both the ETL and HTL layers. Device II showed the best performance among the three configurations, with significant improvements achieved through optimization. The performance of Device II was assessed using the SCAPS-1D simulator, focusing on optimizing doping and defect densities in both the ETL and HTL layers. Additionally, temperature effects and interface flaws were considered in the simulation. The optimal configuration of Device II achieved a maximum PCE of 29.60%, an FF of 84.84%, a V of 0.7378 V, and a J of 47.28 mA/cm. These results set a benchmark for AgAuSe-based solar cells. Devices I and III achieved PCEs of 18.17% and 29.10%, respectively, but Device II remained the top performer. The study optimized solar cell design, with Device II achieving 29.60% efficiency, demonstrating the strong potential of AgAuSe-based hybrid perovskite solar cells, whereas earlier work established AgAuSe as effective for NIR photodetectors but did not explore its photovoltaic applications.
这项工作探索了以银金硫族化物（AgAuSe）为基底的混合钙钛矿太阳能电池的发展。重点是将宽带隙硫族化物电子传输层（ETL）如WS、SnS和CeO与空穴传输层CFTS相结合。分析了三种器件结构：器件I（Al/FTO/WS/AgAuSe/CFTS/Au）、器件II（Al/FTO/SnS/AgAuSe/CFTS/Au）和器件III（Al/FTO/CeO/AgAuSe/CFTS/Au）。该研究考虑了影响器件性能的关键因素，包括掺杂浓度、层厚度、吸收体缺陷密度以及ETL和HTL层的特性。器件II在这三种结构中表现最佳，通过优化实现了显著改进。使用SCAPS - 1D模拟器评估了器件II的性能，重点是优化ETL和HTL层中的掺杂和缺陷密度。此外，在模拟中考虑了温度效应和界面缺陷。器件II的最佳结构实现了最大光电转换效率（PCE）为29.60% ,填充因子（FF）为84.84% ，开路电压（V）为0.7378 V ，短路电流密度（J）为47.28 mA/cm²。这些结果为基于AgAuSe的太阳能电池设定了基准。器件I和器件III的PCE分别为18.17%和29.10% ，但器件II仍然是性能最佳的。该研究优化了太阳能电池设计，器件II实现了29.60%的效率，证明了基于AgAuSe 的混合钙钛矿太阳能电池的强大潜力，而早期的工作证实AgAuSe对近红外光电探测器有效，但未探索其光伏应用。
