Abstract
Conference Title: 2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC) Conference Start Date: 2018, June 10 Conference End Date: 2018, June 15 Conference Location: Waikoloa Village, HI, USA 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 $\times$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.
