TiO2 film decorated with highly dispersed polyoxometalate nanoparticles synthesized by micelle directed method for the efficiency enhancement of dye-sensitized solar cells

Two polyoxometalate (POM) nanoparticles with controlled shape and structure were synthesized by micelle directed method, and then composited with TiO2 via calcination to remove the surfactant to obtain TiO2 complexes with highly dispersed and small-sized polyoxometalate nanoparticles, which were firstly applied as photoanodes for dye-sensitized (N719) solar cells with enhanced photovoltaic performance.314
