报告摘要：
Solution processed bulk heterojunction polymer solar cells (PSCs) attracts more attention due to their potential applications as robust, light-weigh, flexible mobile power sources. To improve the device performance, many new polymers with preferred optoelectronic properties have been synthesized. Parallel with material development, various fabrication techniques and device structures have also been extensively explored. Impressive progress has been made in terms of power conversion efficiency (PCE) during the last decade. In this talk, following a general review of the field, our efforts to improve device efficiency will be introduced from new polymer synthesis to device optimization through controlling morphology of active layers, modifying electrodes, investigating charge generation, recombination and transport in devices.

Dr.Zhang mainly works on organic solar cells (OSCs) from optimizing new materials to exploring new device structures as well as investigation on the factors, which dominate device photovoltaic performance. In the past 12 years, more than 100 synthesized materials (polymers and soluble small molecules) were evaluated and optimized in OSCs. New device structures including ITO free, flexible, multi-folded OSCs, and vacuum free transparent inverted OSCs were explored and successfully fabricated. Most of her research has been published in high impact journals, such as Advanced Materials, Journal of the American Chemical Society and Advanced Functional Materials. She published 82 journal articles with 3601 time citation and h-index 33. Her work on modifying morphology of active layers with mix solvents (2003), using soluble interfacial layer to modifying cathode (2007) and inverted vacuum free transparent solar cells (2009) are all pioneer in the field.
