摘要

We quantified the donor-pi-acceptor (D-pi-A) character of a large number of dyes (116) used in dye-sensitized solar cells (DSSCs) and correlated them with the power conversion efficiency of the corresponding cell. The result indicates that there is no correlation between different measures of D-pi-A strength and efficiency; that is, the effect of the D-pi-A character is completely washed out by other effects. We propose that other design rules should be identified by statistically testing them against the now rich set of experimentally available data.
