We studied the effectiveness of various non-noble metals used as current-collecting grids on fluorine-doped SnO2 (FTO) for dye-sensitized solar cells (DSCs). Non-noble metal grids were deposited by dc magnetron sputtering, and the mechanical adhesion of non-noble metals was improved by a 300 nm thick Cr interlayer between FTO and a grid. The metals were evaluated on the basis of photocurrent-voltage characteristics and impedance spectra. An analysis using an equivalent circuit model showed that such metal grids affect the internal ohmic resistance, which is inversely related to the fill factor. A 1 mu m thick NiCr grid affords a fill factor of 0.639, as much as that of Ag, but with a slightly lower efficiency of 6.4%, which supports the feasibility of using stable non-noble metal grids in DSCs, albeit with a 5% reduction in photovoltaic efficiency.
