Yucheng Liu,Jiankun Sun,Zhou Yang,Dong Yang,Xiaodong Ren,Hua Xu,Zupei Yang,Shengzhong Frank Liu,Shengzhong Frank Liu +8 more
TL;DR: In this paper, an array of 153 photodetectors on a piece of thin wafer, demonstrating feasibility of mass production of integrated circuits on the perovskite wafer is designed and prepared.
Journal ArticleDOI
Solution-Processed Nb:SnO2 Electron Transport Layer for Efficient Planar Perovskite Solar Cells
Xiaodong Ren,Dong Yang,Zhou Yang,Jiangshan Feng,Xuejie Zhu,Jinzhi Niu,Yucheng Liu,Wangen Zhao,Shengzhong Frank Liu,Shengzhong Frank Liu +9 more
TL;DR: Experimental analyses reveal that the Nb:SnO2 ETL significantly enhances the electron extraction and effectively suppresses charge recombination, leading to improved solar cell performance.
Journal ArticleDOI
Thinness- and Shape-Controlled Growth for Ultrathin Single-Crystalline Perovskite Wafers for Mass Production of Superior Photoelectronic Devices.
Yucheng Liu,Yunxia Zhang,Zhou Yang,Dong Yang,Xiaodong Ren,Liuqing Pang,Shengzhong Frank Liu,Shengzhong Frank Liu +7 more
TL;DR: Thinness-controlled perovskite wafers are directly prepared using a geometry-regulated dynamic-flow reaction system and are found to be a superior material for photodetectors with a photocurrent response 350 times higher than that made of microcrystalline thin films.
