在过去的十年中，超导太阳能电池（PSC）有了显著的改进，效率提高，并逐渐克服了温度和湿度引起的不稳定性的障碍。结合了3D钙钛矿的高电荷载流子寿命和迁移率、强吸收和良好结晶度与2D钙钛矿的疏水性质的联合收割机材料已经成为用于太阳能电池的特别有希望的候选者。为了充分理解这些2D-3D混合体系的光电性质，在0. 0000 - 0. 00000的组成范围内研究了混合钙钛矿BA（x）（FA（0. 83）Cs（0. 17））（1-x）Pb（I 0. 6 Br 0. 4）（3
Perovskite solar cells (PSCs) have improved dramatically over the past decade, increasing in efficiency and gradually overcoming hurdles of temperature- and humidity-induced instability. Materials that combine high charge-carrier lifetimes and mobilities, strong absorption, and good crystallinity of 3D perovskites with the hydrophobic properties of 2D perovskites have become particularly promising candidates for use in solar cells. In order to fully understand the optoelectronic properties of these 2D-3D hybrid systems, the hybrid perovskite BA(x)(FA(0.83)Cs(0.17))(1-x)Pb(I0.6Br0.4)(3) is investigated across the composition range 0
