Research Progress on the Application of D-A-π-A Featured Sensitizer in the Dye Sensitized Solar Cells

Abstract

Guan, Junjie Abstract The donor-π bridge-acceptor (D-π-A) configuration becomes mainstream in the design of organic sensitizers due to its enhancement of the intramolecular photo-generated charge-transfer. On the basis of traditional D-π-A structure, researchers incorporate additional electron-withdrawing unites into the π bridge as internal acceptor, termed as D-A-π-A configuration, which displays better performance. This review summarizes the molecular design (since 2012) of sensitizers based on D-A-π-A configuration and their application in the dye sensitized solar cells.
