英文摘要	We simulated the performance of recently developed highly efficient bulk heterojunction photovoltaic cells with poly [N-9 ''-hepta-decanyl-2,7-carbazole-alt-5,5-(4',7'-di-2-thienyl-2',1',3'-benzothiadiazole)] as the donor and [6,6]-phenyl C(70)-butyric acid methyl ester as the acceptor, using a device model. The simulated current-voltage curve is in excellent agreement with the experiment. This enables us to analyze how microscopic processes of excitons and charges govern the device performance. The influence of dissociation rate and decay rate of photoinduced electron-hole pairs on the open-circuit voltage V(OC) is investigated. It is shown that a high dissociation rate relative to decay rate will lead to enhanced V(OC). (C) 2010 American Institute of Physics. [doi:10.1063/1.3494527]
