Upscaling Solution‐Processed Perovskite Photovoltaics

The performance of hybrid organic–inorganic perovskite solar cells has reached a certified efficiency 25.5% over the past decade, which attracted significant attention as promising candidate for photovoltaic (PV) applications. However, most efficient were produced by technique spin coating, is extremely limited in terms upscaling production commercialization technology. Furthermore, efficiencies large-area modules are still significantly lower than those lab size cells. Thus, there some challenges that need to be overcome bridge gap between small-area and devices. first challenge lies preparing high-quality layers low-cost scalable techniques with high reproducibility. Second, selecting depositing charge extraction well bottom top electrodes essential tasks. In this review, recent progress technologies solution-based coating printing PVs summarized analyzed. Based on analysis, strategies opportunities proposed promote development stable PV toward commercialization.
