Recently, the design and fabrication of lead (Pb)-free perovskite or perovskite-like materials have received great interest for the development of perovskite solar cells (PSCs). Manganese (Mn) is a less toxic element, which may be an alternative to Pb. In this work, we explored the role of NH(CH)NHMnCl perovskite as a light absorber layer via SCAPS-1D. A Pb-free PSC device (FTO/TiO/NH(CH)NHMnCl/spiro-OMeTAD/Au) was simulated via SCAPS-1D software. The simulated Pb-free PSCs (FTO/TiO/NH(CH)NHMnCl/spiro-OMeTAD/Au) showed decent power conversion efficiency (PCE) of 20.19%. Further, the impact of the thickness of absorber (NH(CH)NHMnCl), electron transport (TiO), and hole-transport (spiro-OMeTAD) layers were also investigated. Subsequently, various electron transport layers (ETLs) were also introduced to investigate the role of ETL. In further studies, an NH(CH)NHMnCl-based PSC device (FTO/TiO/NH(CH)NHMnCl/spiro-OMeTAD/Au) was also developed (humidity = ~30-40%). The fabricated PSCs displayed an open circuit voltage (Voc) of 510 mV with a PCE of 0.12%.
最近，无铅钙钛矿或类钙钛矿材料的设计与制备在钙钛矿太阳能电池（PSC）的发展中受到了极大关注。锰（Mn）是一种毒性较小的元素，可能是铅的替代品。在本工作中，我们通过SCAPS-1D探索了NH(CH)NHMnCl钙钛矿作为光吸收层的作用。利用SCAPS-1D软件模拟了一种无铅PSC器件（FTO/TiO/NH(CH)NHMnCl/spiro-OMeTAD/Au）。模拟的无铅PSC（FTO/TiO/NH(CH)NHMnCl/spiro-OMeTAD/Au）显示出20.19%的良好功率转换效率（PCE）。此外，还研究了吸收层（NH(CH)NHMnCl）、电子传输层（TiO）和空穴传输层（spiro-OMeTAD）厚度的影响。随后，还引入了各种电子传输层（ETL）来研究ETL的作用。在进一步的研究中，还开发了一种基于NH(CH)NHMnCl的PSC器件（FTO/TiO/NH(CH)NHMnCl/spiro-OMeTAD/Au）（湿度约为30 - 40%）。制备的PSC显示出510 mV的开路电压（Voc），功率转换效率为0.12%。
