Extreme mechanical flexibility is highly desirable for the new generation of Mono-Crystalline Silicon solar cells while maintaining the high power conversion efficiency. Here, we show a novel corrugation architecture, which transforms rigid interdigitated back contact 5 ×5 inch c-Si solar wafers into an ultra-flexible (140 m bending radius) version while retaining its original efficiency of 17%. We also investigated using both fluorine-based plasma and Ytterbium fiber laser for forming the corrugation architecture.
