Polymer-Passivated Inorganic Cesium Lead Mixed-Halide Perovskites for Stable and Efficient Solar Cells with High Open-Circuit Voltage over 1.3 V.
Qingsen Zeng,Xiaoyu Zhang,Xiaolei Feng,Siyu Lu,Zhaolai Chen,Xue Yong,Simon A. T. Redfern,Haotong Wei,Hai-Yu Wang,Huaizhong Shen,Wei Zhang,Weitao Zheng,Hao Zhang,John S. Tse,Bai Yang +14 more
TL;DR: It is demonstrated that polythiophene, deposited on the top of CsPbI2 Br, can significantly reduce electron-hole recombination within the perovskite, which is due to the electronic passivation of surface defect states, and the interfacial properties are improved by a simple annealing process.

Electron-hole diffusion lengths > 175 μm in solution-grown CH3NH3PbI3 single crystals
TL;DR: It is found that the diffusion lengths in CH3NH3PbI3 single crystals grown by a solution-growth method can exceed 175 micrometers under 1 sun (100 mW cm−2) illumination and exceed 3 millimeters under weak light for both electrons and holes.
