| 英文摘要 | this study investigated theoretical photoinduced charge transport in a bulk heterojunction (bhj) solar cell controlled by an external electric field. our method for visualizing charge difference density identified the excited state properties of photoinduced charge transfer, and the charge transfer excited states were distinguished from local excited states during electronic transitions. furthermore, the calculated rates for the charge transfer revealed that the charge transfer was strongly influenced by the external electric field. the external electric field accelerated the rate of charge transfer by up to one order when charge recombination was significantly restrained. our research demonstrated that photoinduced charge transport controlled by an external electric field in a bhj solar cell is efficient, and the exciton dissociation is not the limiting factor in organic solar cells. our research should aid in the rational design of a novel conjugated system of organic solar cells. |
