The transmittance spectra of TCO substrates were controlled with the thickness of c-TiO2 layers, which in turn, influenced the incident photon-to-current conversion efficiency of DSSCs. The overall energy conversion efficiency of the DSSC with a 210 nm-thick c-TiO2 layer was increased by 16% compared to the DSSC with a 40 nm-thick c-TiO2 layer, due to the higher optical transmittance of the TCO substrate.
