文摘

Environment-friendly non-halogenated solvents were used to spray-coat the active layers. Both drying kinetics and charge decay dynamic of spray-processed films were systematically investigated. Substrate temperatures have a great effect on the spray-coated film morphology. Spray-processed films with randomly textured surface provide a simple and efficient route to increase light absorption. Spray-coated ITO-free inverted solar cells processed from non-halogenated solvents were fabricated for the first time.
