Abstract

Although tin oxide (SnO2) has been employed recently as an efficient electron-transporting layer (ETL) to realize highly efficient perovskite solar cells (PVSCs), it is still quite challenging to apply it through facile solution-based synthesis at low enough temperature to be compatible with the roll-to-roll printing on polymer substrates. In this work, a combustion method has been successfully adapted to modulate the exothermic characteristics and processing temperature (150 °C) of SnO₂ to achieve homogeneous and crystalline thin film as efficient ETL for PVSCs. The combustion SNO₂ ETL shows high electric conductivity, and matched energy level, which leads to a good power conversion efficiency of 13.76%. This newly developed combustion SnO₂ has the high potential to provide a facile pathway to fabricate the low temperature processing, roll-to-roll, and high performance PVSCs.
