Abstract

Amorphous tin-indium-oxide (TIO) thin films as an electron transport layer (ETL) for perovskite solar cells (PSCs), were grown under controlled oxygen partial pressure (PO₂). The effect of PO₂ during TIO deposition on the photovoltaic response of TIO-ETL-based PSC was evaluated. A device of TiCl₄ treated TIO-77 at.% deposited under lower PO₂ shows improved shunt resistance and exhibited the best power conversion efficiency of 15%, which is greater than the devices deposited at high PO₂. This work deciphers the importance of deposition atmosphere in fabricating ETLs for PSCs.
