摘要

窄带隙 AgTaS3 包晶可以提供高效薄膜太阳能电池（SC），并成为市场上领先的硅太阳能电池。在此，我们利用太阳能电池电容模拟器（SCAPS-1D）研究了 n-CdS/p-AgTaS3/p+-Al0.8Ga0.2Sb 器件在厚度、掺杂浓度和各层缺陷密度变化时的响应。优化后的电池显示出 0.78 V 的 VOC、27.89% 的 PCE 和 46.37 mA/cm2 的 JSC，以及 77.06% 的填充因子，为性能卓越的新型双异质结包晶光伏（PV）电池铺平了道路。

Design and performance evaluation of all-inorganic AgTaS3 perovskite solar cells

Narrow bandgap AgTaS₃ perovskite can offer highly efficient thin film solar cells (SCs) and become Si counterparts that are leading in the market. Herein, we study the response of a n-CdS/p-AgTaS₃/p⁺-Al_0.8Ga_0.2Sb device according to the variation of thickness, doping concentration, and defect densities in each layer using a solar cell capacitance simulator (SCAPS-1D). The optimized cell shows a V_OC of 0.78 V, PCE of 27.89% accompanied by a J_SC of 46.37 mA cm⁻², and a fill factor of 77.06%, paving the way for novel double heterojunction perovskite photovoltaic (PV) cells with remarkable performance.
