A research team led by Prof. Gang Li invented a novel stretchable Organic Photovoltaic (OPV) device with a surface-texturing substrate delivering a comparable power conversion efficiency (PCE) of 20.5% comparing 20.8% for the rigid device. The texturing stretchable substrate provides a new direction for achieving high performance and enhanced light utilization for the stretchable light-harvesting device, which is suitable for both indoor and outdoor applications. As the first author, Prof. Li’s PhD student, Jiaming Huang, has published a paper “Stretchable ITO‐Free Organic Solar Cells with Intrinsic Anti‐Reflection Substrate for High‐Efficiency Outdoor and Indoor Energy Harvesting” on the top-tier materials science journal, Advanced Functional Materials (2019 Impact Factor of 16.836) about this invention. This journal reports breakthrough research in all aspects of materials science, including nanotechnology, chemistry, physics, and biology every week. The paper can be read online at https://onlinelibrary.wiley.com/doi/full/10.1002/adfm.202010172.
