Dye-sensitized solar cells (DSC) has been considered as one of the most promising alternatives to conventional photovoltaic device due to its low cost, simple fabrication process and high conversion efficiency. Pt-loaded conducting substrate has been widely exploited as the standard counter electrode for DSC. However, Pt is expensive and rare, so it is most desirable to seek a low-cost substitute for Pt in counter electrode of DSC. Transition metal compound has been demonstrated to be one of the most promising counter electrode materials for DSCs owing to its low cost, simple fabrication, broad variety of materials and good catalytic activity. This article provides a review of transition metal compound counter electrodes for DSC and a brief outlook on the future development of transition metal compound counter electrodes.
