Electron lifetimes in dye-sensitized solar cells employing a porphyrin dye, an organic dye, a 1:1 mixture of the two dyes and a di-chromophoric dye design consisting of the two dyes using a non-conjugated linker were measured, suggesting that the dispersion force of the organic dyes has a significant detrimental effect on the electron lifetime and that the di-chromophoric design can be utilized to control the effect of the dispersion force.
