title: Organic dyes with remarkably high absorptivity; all solid-state dye sensitized solar cell and role of fluorine substitution.
abstract: A series of new organic D-pi-A dyes, A1, A2-H and A2-F, possessing a remarkably high absorption extinction coefficient of epsilon > 5.0 x 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 optimized parameters of eta = 4.86%, J(SC) = 7.52 mA cm(-2), V(OC) = 0.91 V, and FF = 0.71.
