Organic dyes with remarkably high absorptivity; all solid-state dye sensitized solar cell and role of fluorine substitutionElectronic supplementary information (ESI) available: Experimental details. See DOI: 10.1039/c0cc00808g
A series of new organic D-π-A dyes, A1, A2-H and A2-F, possessing a remarkably high absorption extinction coefficient of > 5.0 × 10 4 M −1 cm −1 at peak wavelength were synthesized, among which, A2-F having a key fluorine substitution attains excellent all solid-state DSSC performance, with optim...
