文摘
- •
A nonuniform electric field in polymer-based D/A photovoltaic system is supposed.
- •
Under such an electric field, migration of an exciton along a polymer chain is presented.
- •
The exciton migration mechanism is clarified by introducing a driving force.
- •
Factors affecting the exciton migration speed are also discussed.
