摘要：
Through cooperative interactions, each of the three organic dyes utilized achieved improved sensitizing abilities on nanocrystalline TiO2 electrodes in co-sensitization over single-dye-sensitization, which led to a wide ( 400 - 700 nm) and highly efficient ( exceeding 70%) photocurrent action spectrum in triple-dye-sensitization and an overall power conversion efficiency (eta) of 6.5% (AM1.5, 80 mW cm(-2)), the highest eta to date for dye-sensitized solar cells (DSSCs) based on the co-sensitization of plural organic dyes, fully demonstrating the potential of co-sensitization in DSSC applications.
