Title: Method of making a photovoltaic device on a substrate at high speed with perovskite solution

Abstract

A continuous inline method for production of photovoltaic devices at high speed includes: providing a substrate; depositing a first carrier transport solution layer with a first carrier transport deposition device to form a first carrier transport layer on the substrate; depositing a Perovskite solution comprising solvent and perovskite precursor materials with a Perovskite solution deposition device on the first carrier transport layer; drying the deposited Perovskite solution to form a Perovskite absorber layer; and depositing a second carrier transport solution with a second carrier transport deposition device to form a second carrier transport layer on the Perovskite absorber layer, wherein the deposited Perovskite solution is dried at least partially with a fast drying device which causes a conversion reaction and the Perovskite solution to change in optical density by at least a factor of 2 in less than 0.5 seconds after the fast drying device first acts on the Perovskite solution.
