Alfa Chemistry - Acceptor Materials For Solar Energy

Acceptor Materials For Solar Energy: Acceptor materials with excellent performance generally have the following conditions: (1) strong and wide absorption in the visible light region; (2) longer exciton diffusion length, so that excitons can efficiently migrate to the donor-acceptor interface; (3) higher LUMO energy level; (4) higher electron mobility; (5) good charge transfer ability. The structurally rich acceptor materials endow OPV devices with excellent properties and expand the application fields of OPV devices.
