In ambient air includes steps of forming a perovskite film on a substrate by spin-coating, the perovskite film having a turbid point when the perovskite film transitions from transparent to turbid in appearance, and dropping an antisolvent on the perovskite film during an antisolvent window having a start time five seconds before the turbid point and an end time one second before the turbid point. The method also includes the step of measuring the current relative humidity of the ambient air at the time of manufacture and adjusting the antisolvent window or optimum drop time of the antisolvent based upon the current relative humidity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for manufacturing perovskite-based devices in ambient air","description":"A method for manufacturing perovskite-based devices, such as solar cells.
