Tin oxide, SnO2, transparent conducting oxide (TCO) films for dye-sensitized solar cells (DSSCs) was investigated. We found that an electrical conductivity is not the only parameter that governs conversion efficiency of DSSC. The conversion efficiency was strongly influenced by haze ratio that is easily tuned by controlling the surface morphology of TCO layer by spray pyrolysis deposition (SPD) technique. The conversion efficiency was enhanced as high as 7.6%, attributing to an effective incident light harvest of a working electrode in the consequence of the confinement of the incident light within the cell.
