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.

Electronic Processes in Ionic Crystals
TL;DR: Mott and Gurney's book on electrons in ionic crystals, the authors, is an excellent and perhaps the first monograph on applied theoretical physics and has been used for many applications of modern theoretical physics to questions of appreciable technical importance.
Journal ArticleDOI
Organometal Trihalide Perovskite Single Crystals: A Next Wave of Materials for 25% Efficiency Photovoltaics and Applications Beyond?
TL;DR: In this article, the authors present an overview of the historic evolution in understanding of carrier diffusion length in CH3NH3PbI3, the initial investigations of the synthesis of single crystalline hybrid perovskites, and the characterization of their optoelectronic properties.
Journal ArticleDOI
Reassessment of the intrinsic carrier density in crystalline silicon in view of band-gap narrowing
TL;DR: In this paper, a random-phase approximation model for band-gap narrowing was proposed to obtain the intrinsic carrier density of crystalline silicon at 300 K. This value is consistent with results obtained by Misiakos and Tsamakis, J. Appl. Phys. 74, 3293 (1993), using capacitance measurements.

Self-Template-Directed Synthesis of Porous Perovskite Nanowires at Room Temperature for High-Performance Visible-Light Photodetectors
TL;DR: The initial formation of CH3 NH3 PbBr3 perovskite layers on the surface of the precursor nanowires and the following dissolution of the organic component of the latter led to the formation of mesopores and the preservation of the 1D morphology.

TL;DR: Structural inhomogeneity on a micrometer-scale across a CH3NH3PbI3 single crystal is responsible for a local modulation of the optical band gap, which is also highly sensitive to humidity.
