This paper includes the theoretical investigation performed on the device having structure FTO/TiO/CHNHPbI/PeDAMAPbI/Spiro- OMeTAD. This work is focused on the effects of ETLs and HTLs on the performance of the device structure. Device simulation and various parameters of the perovskite cell are investigated with the help of SCAPS-1D software. In recent years, perovskite solar cells (PSCs) have passed through many advancements but they suffered through instability due to moisture. Due to poor stability of PSCs becomes a major obstacle for its commercialization. This leads to the development of 2D perovskite manufactured from organic cations and inorganic slabs arranged alternately.2D perovskite is of two kinds: Ruddlesden - Popper (RP) phase and Dion-Jacobson (DJ) phase. Both types of 2D perovskite are observed to be much more stable than 3Dperovskite. Due to its stability, it becomes an alternative for 3D perovskite. To improve the stability and efficiency of 2D perovskite both types of 2D phases are merged. To have more stability organic cations are introduced between inorganic slabs which reduces charge transportation. Proposed DJ 2D-3D perovskite solar cells provide an impressive efficiency of 26.03 % even when exposed to much temperature and moisture. Being much more efficient and stable the 2D-DJ/3D perovskite becomes an option to be utilized in photovoltaic applications.

高效稳定的 Dion-Jacobson(DJ) 2D-3D 钙钛矿太阳能电池，转换效率为 26%：SCAPS-1D 研究

本文包括对结构为 FTO/TiO/CHNHPbI/PeDAMAPbI/Spiro-OMeTAD 的器件进行的理论研究。这项工作的重点是 ETL 和 HTL 对器件结构性能的影响。借助 SCAPS-1D 软件研究了器件模拟和钙钛矿电池的各种参数。近年来，钙钛矿太阳能电池（PSC）取得了许多进步，但由于水分而不稳定。由于PSC稳定性差成为其商业化的主要障碍。这导致了由有机阳离子和无机板交替排列制造的二维钙钛矿的发展。二维钙钛矿有两种：Ruddlesden-Popper（RP）相和Dion-Jacobson（DJ）相。据观察，两种类型的 2D 钙钛矿都比 3D 钙钛矿稳定得多。由于其稳定性，它成为 3D 钙钛矿的替代品。为了提高二维钙钛矿的稳定性和效率，两种类型的二维相被合并。为了具有更高的稳定性，在无机板之间引入有机阳离子，这减少了电荷传输。所提出的 DJ 2D-3D 钙钛矿太阳能电池即使暴露在高温和潮湿环境下也能提供 26.03% 的令人印象深刻的效率。 2D-DJ/3D 钙钛矿更加高效和稳定，成为光伏应用中的一种选择。
