Large‐Area Blade‐Coated Solar Cells: Advances and Perspectives

Abstract High‐efficiency perovskite solar cells (PSCs) and organic solar cells (OSCs) are promising alternatives for silicon‐based solar cells. At present, the key point for commercialization of PSCs and OSCs is realizing large‐scale production while maintaining the same high efficiency as small‐area ones. In this review, the blade‐coating method for preparing large‐area films is introduced first and the recent advances of blade‐coated OSCs and PSCs are summarized. Then, the effects of blading parameters on the crystal growth and film formation of the light‐harvesting materials are discussed. Moreover, the limitations and advantages of making high‐quality films via blade‐coating are discussed. Finally, some strategies for the up‐scaling of solar cells via blade‐coating are proposed.
