Abstract

Abstract : The Front Cover shows a novel planar inorganic CsPbI2 Br perovskite solar cell with Nb2 O5 as electron transportation layer. Expensive and unstable organic hole‐transport layers and noble‐metal electrodes can be replaced by low‐cost carbon electrode. This research also demonstrates that rubidium ion could effectively passivate the CsPbI2 Br film, which leads to increased structure stability and improved conversion efficiency due to suppressed trap states. The image also conveys the theme that inorganic CsPbI2 Br perovskite solar cells could generate electricity under a tough and high‐temperature aggressive environment. More information can be found in the Full Paper by Guo et al. onpage 983 in Issue 5, 2019 (DOI:10.1002/cssc.201802690 ).
