Crystal recombination control by using Ce doped in mesoporous TiO₂ for efficient perovskite solar cells.

ABSTRACT: Efficient electron transport layers (ETLs) are the crucial issue for electron transport and hole blocking in organic-inorganic hybrid perovskite solar cells (PSCs). To date, most of the reported effective ETLs have comprised TiO₂, which exhibits limited electron mobility and numerous defect states and restricts the enhancement of the performance of PSCs. Hence, the investigation of effective tactics for improving the electronic properties of TiO₂ is critical for the fabrication of high-efficiency devices. In this study, a cerium doping method was adopted in mesoporous TiO₂, which was prepared via a traditional one-step hydrothermal process, to improve its electron transport properties by recombining nanocrystals and optimizing the negative flat band
