摘要

Polymer solar cell (PSC) is a promising photovoltaic technology for clean and renewable energy sources owing to its mechanical flexibility and large-area,low-cost manufacturing compatibility.Significant progress in device performance has been made in the recent years through the development of new materials,morphology control in photo-active layer,interface engineering in multi-layer device,and device fabrication processes.However,further improvement in efficiency exceeding 10％ in single-junction PSCs remains a daunting challenge for commercial applications owing to the compromise between optical absorption and charge transport in the active layer.
