Abstract

We report the performance of perovskite solar cells (PSCs) with an electron transport layer (ETL) consisting of a SnO₂ thin film obtained by electrochemical deposition. The surface morphology and thickness of the electrodeposited SnO₂ films were closely related to electrochemical process conditions, i.e., the applied voltage, bath temperature, and deposition time. We investigated the performance of PSCs based on the SnO₂ films. Remarkably, the experimental factors that are closely associated with the photovoltaic performance were strongly affected by the SnO₂ ETLs. Finally, to enhance the photovoltaic performance, the surfaces of the SnO₂ films were modified slightly by TiCl₄ hydrolysis. This process improves charge extraction and suppresses charge recombination.
