Recent Progress in Coating Methods for Large‐Area Perovskite Solar Module Fabrication

The technological requirements are changing, and there is a push for more effective energy production and conversion technologies as a result of a social desire for sustainable and renewable energy sources. Solar energy conversion, particularly photovoltaic cells, offers a potentially helpful solution in this situation. Power conversion efficiency (PCE) of perovskite solar cells (PSCs) has been reported to have increased significantly from 3% to 26.1%. The transition from laboratory PSCs to their commercialization needs scalable deposition techniques, high efficiency at a scalable level, and perovskite photovoltaic with minimal loss in PCE. In this review article, the scalable fabrication processes for perovskite solar modules (PSMs) and their fabrication challenges, as well as latest developments in PSM stability, are focused on. Finally, the future prospectus and challenges for PSMs are presented. This review will give us an overall understanding of the thin film coating inside the PSM and good insight into the future direction of development.
