Greatly enhanced photovoltaic performance by introducing hydroxyl or benzene ring into D-pi-A dye framework: Dye sensitized solar cells based on rhodanine dyes
The introduction of hydroxyl group into aniline moiety (electron donor, D) or benzene ring into the conjugation chain (pi bridge) of D-pi-A dye framework with rhodanine-3-acetic acid as electron acceptor (A) improved remarkably the monochromatic incident photon-to-current conversion efficiencies (IPCEs) and overall power conversion efficiencies (eta), fully demonstrating the potential of molecular design in developing efficient D-pi-A dyes for dye-sensitized solar cell applications.
