Abstract

We demonstrated that TiO ₂ compact layers (c-TiO ₂) can modulate optical transmittance of transparent conducting oxide (TCO) substrates and improve spectral response of a dye-sensitized solar cell (DSSC). The transmittance spectra of TCO substrates were controlled with the thickness of c-TiO ₂ 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-TiO ₂ layer was increased by 16% compared to the DSSC with a 40 nm-thick c-TiO ₂ layer, due to the higher optical transmittance of the TCO substrate.
