 perovskite solar cells have been successfully demonstrated at the laboratory scale but need to be adapted for industrial use. Large scale manufacturing and processing methods have been developed to enable the transition from lab scale to industrial scale production. These include printing, coating, and vacuum slash vapor deposition techniques, which can be used to produce large area cells and modules. Additionally, flexible substrate production allows for the development of roll-to-roll production, which has numerous advantages for various applications.
