Ultrasonic spraying process technology for fabricating large-area perovskite solar cells

Organic-inorganic hybrid perovskite solar cells are on the verge of a breakthrough in photovoltaic technology. Roll-to-roll and large-area processing have become key challenges that must be addressed before commercialization. In this study, a scalable ultrasonic spray deposition method for high-throughput coating of perovskite photoactive layers with a large active area was realized by precisely controlling the concentration of the precursor solution and the spraying channel. Films with large crystallites and suitable thicknesses of ~350 nm can be easily developed by one-step direct ultrasonic spraying.
