Emerging perovskite solar cells (PSCs) are facing environmental toxicity issues due to lead-based perovskites, and long-term stability remains a challenge. In recent years, silver bismuth iodides (AgBiI) have gained attention as an absorber due to their lead-free, non-toxic, and cost-effective characteristics. However, device performance is still low so research is necessary to make it marketable. In this study, SCAPS-1D simulation is utilized to develop PSCs with an AgBiI absorber, CTBTAPH Hole transport layer (HTL), and four distinct electron transport layers (ETLs) (STO, MZO, ZnSe, PCBM) under standard illumination. In light of these factors, a thorough investigation of the FTO/ETL/AgBiI/CTBTAPH/Au combination was conducted to evaluate the influence of power conversion efficiency (PCE). For each of the four assessed combinations, modifications were made to the absorber, the HTL, the ETL thickness, the acceptor density of the HTL, the acceptor doping, and the defect density of the absorber. The effects of these topologies on quantum efficiency, - characteristics, generation and recombination processes, series and shunt resistance, and temperature impact were also investigated. In the end, the most effective cell in this investigation was the FTO/MZO/AgBiI/CTBTAPH/Au configuration with a PCE of 20.72%, of, of, and FF of at 300 K temperature. The previously described results have the potential to significantly advance the development of lead-free PSCs, which are more environmentally friendly and efficient, thereby opening the door for their eventual widespread use.
新兴的钙钛矿太阳能电池（PSC）由于基于铅的钙钛矿而面临环境毒性问题，并且长期稳定性仍然是一个挑战。近年来，碘化银铋（AgBiI）因其无铅、无毒且具有成本效益的特性而作为吸收层受到关注。然而，器件性能仍然很低，因此有必要进行研究以使其具有市场竞争力。在本研究中，利用SCAPS-1D模拟在标准光照下开发具有AgBiI吸收层、CTBTAPH空穴传输层（HTL）和四种不同电子传输层（ETL）（STO、MZO、ZnSe、PCBM）的PSC。鉴于这些因素，对FTO/ETL/AgBiI/CTBTAPH/Au组合进行了全面研究，以评估功率转换效率（PCE）的影响。对于四种评估组合中的每一种，都对吸收层、HTL、ETL厚度、HTL的受体密度、受体掺杂以及吸收层的缺陷密度进行了修改。还研究了这些拓扑结构对量子效率、-特性、产生和复合过程、串联和并联电阻以及温度影响的作用。最终，本研究中最有效的电池是FTO/MZO/AgBiI/CTBTAPH/Au配置，在300K温度下PCE为20.72%， ， ，填充因子为 。上述结果有可能显著推动更环保、更高效的无铅PSC的发展，从而为其最终广泛应用打开大门。
