摘要

•The properties of amorphous-SnO2 treated with intense-pulsed-light (IPL) process are discussed.•IPL irradiation eliminates surface −OH and enables the growth of a low-stress perovskite film.•A PCE of 17.68% was achieved from a PSC based on the IPL-treated amorphous-SnO2.•Ultrafast processing time and undamaged obtained films brighten the future of IPL technology.
