Due to its excellent thermal stability and high performance, inorganic cesium lead mixed halide (ABX3, where A = Cs, B = Pb, and X = I/Br) all‐inorganic perovskite solar cells (IPVSCs) have attracted much interest in optoelectronic applications. However, the film quality, enough absorption by desired film thickness, and nature of partial replacement of cations determine the stability of the CsPbI2Br perovskite films. Herein, a hot air method is used to control the thickness and morphology of the CsPbI2Br perovskite thin film, and the A‐site (herein, Cs+) cation is partially incorporated by rubidium (Rb+) cations for making the stable black phase under ambient conditions. The Rb cation‐incorporated Cs1−xRbxPbI2Br (x = 0–0.03) perovskite thin films exhibit high crystallinity, uniform grains, extremely dense, and pinhole‐free morphology. The fabricated device with its Cs0.99Rb0.01PbI2Br perovskite composition with poly(3‐hexylthiophene‐2,5‐diyl) as a hole‐transporting layer exhibits a power conversion efficiency (PCE) of 17.16%, which is much higher than that of CsPbI2Br‐based IPVSCs. The fabricated Cs0.99Rb0.01PbI2Br‐based IPVSC devices retain >90% of the initial efficiency over 120 h at 65 °C thermal stress, which is much higher than that of CsPbI2Br samples.

A-Site C阳离子结合CsPbI2Br全无机钙钛矿太阳能电池效率超过17％
无机铯钙混合卤化物（ABX 3，其中A = Cs，B = Pb，X = I / Br）由于其出色的热稳定性和高性能而引起了人们对光电二极管的广泛兴趣应用程序。然而，膜的质量，所需膜厚度的足够吸收以及阳离子部分取代的性质决定了CsPbI 2 Br钙钛矿膜的稳定性。在本文中，使用热风法控制CsPbI 2 Br钙钛矿薄膜的厚度和形貌，and原子（此处为Cs +）阳离子通过by（Rb +）阳离子以在环境条件下产生稳定的黑相。掺有Rb阳离子的Cs 1 - x Rb x PbI 2 Br（x = 0-0.03）钙钛矿薄膜具有高结晶度，均匀晶粒，极致密和无针孔形态。带有Cs 0.99 Rb 0.01 PbI 2 Br钙钛矿成分并以聚（3-己基噻吩-2,5-二基）为空穴传输层的制造的器件显示出17.16％的功率转换效率（PCE），远高于该CsPbI的2基于BR-IPVSCs。制备的Cs 0.99 Rb 0.01 PbI 2在65°C的热应力下，基于Br的IPVSC器件在120 h内能保持90％的初始效率，远高于CsPbI 2 Br样品的效率。
