标题： Impact of Doping Spiro-OMeTAD with Li-TFSI, FK209, and tBP on the Performance of Perovskite Solar Cells

摘要： 本研究深入探讨了掺杂Spiro-OMeTAD（一种广泛使用的钙钛矿太阳能电池空穴传输材料HTM）对三种不同杂质的影响：锂双(三氟甲磺酰基)亚胺（Li-TFSI）、FK209和叔丁基吡啶（tBP）。 重点在于它们对关键光伏参数的影响，包括填充因子（FF）、功率转换效率（η）、短路电流密度（Jsc）和开路电压（Voc）。 通过使用先进的模拟工具，我们系统地比较了未掺杂和掺杂Spiro-OMeTAD结构的性能。 在所考察的掺杂物中，Li-TFSI表现出最显著的增强效果，显著提高了FF和效率。 相比之下，FK209和tBP使设备性能获得中等程度的提升。 这些结果突显了Li-TFSI掺杂所带来的卓越电荷传输特性及其优化HTM功能的能力，从而提供了一种提高钙钛矿太阳能电池效率和稳定性的有前景的方法。 显示英文摘要

摘要： This study delves into the effects of doping Spiro-OMeTAD, a widely employed hole transport material (HTM) in perovskite solar cells, with three distinct impurities: lithium bis(trifluoromethanesulfonyl)imide (Li-TFSI), FK209, and tertbutylpyridine (tBP). The focus lies on their influence on critical photovoltaic parameters, including Fill Factor (FF), power conversion efficiency (eta), short-circuit current density (Jsc), and open-circuit voltage (Voc). Employing advanced simulation tools, we systematically compare the performance of undoped and doped Spiro-OMeTAD structures. Among the examined dopants, Li-TFSI exhibits the most pronounced enhancements, significantly improving both FF and efficiency. In contrast, FK209 and tBP yield moderate gains in device performance. These results underscore the superior charge transport properties imparted by Li-TFSI doping and its capacity to optimize HTM functionality, thereby presenting a promising approach to advancing the efficiency and stability of perovskite solar cells
