Back‐contact silicon solar cells feature high efficiencies, simpler module assembly, and improved aesthetics. The emitter wrap through (EWT) cell structure is particularly attractive for use with industrial processing (e.g., screen‐printed metallization) and common solar‐grade p‐type Si materials. We report development of a high‐efficiency EWT back‐contact cell using p‐type Cz silicon and only industrial...
