New vapor deposition tech could accelerate commercialization of perovskite solar cells

A U. S. -based team developed a vapor deposition technique to fabricate outperforming all-inorganic perovskite thin films in under 5 minutes in a continuous process. The adoption of the proposed approach may also result in higher perovskite solar cell power conversion efficiencies. Researchers in the United States developed a novel vapor deposition method for all-inorganic perovskite absorbers using continuous flash sublimation (CFS). They described the new technique as a non-batch process that solves two problems associated with the use of established vapor processing in perovskite material manufacturing ...
