摘要：

Co-sensitization of nanocrystalline TiO2 with the organic dye D2 and the zinc phthalocyanine dye TT1 improves light harvesting, J(sc) and efficiency of DSC devices. However, the V-oc of the co-sensitized cell is markedly inferior (similar to 130 mV) when compared to the reference device made with D2 only. We discuss the implications of our results with regard to selection criteria for dyes for co-sensitized DSCs.
