摘 要：This is a highly productive research project (13 papers in three years, on journals of Nature Photonics, Advanced Materials, Advanced Functional Materials, Angewandte Chemie International Edition, etc) aiming to (a) understand the potential of conjugated polymer based solar cell under simulated space radiation conditions, (2) develop and improving tandem polymer solar cell structures - constantly pushing the envelope of organic solar cell performance; (3) develop novel polymers for high efficiency OPV. In addition, we also conducted research in utilizing metal grating electrode to improve OPV light harvesting.
