Abstract :
Two Keggin-type polyoxometalates [K6CoIIW12O40 (denoted as {CoIIW12}) and K5CoIIIW12O40 (denoted as {CoIIIW12})] were firstly employed as the redox couple in dye-sensitized solar cells. Photocurrent density–photovoltage curves, cyclic voltammetry curves, photocurrent action spectra and UV–vis spectra demonstrated that {CoIIW12} and {CoIIIW12} displayed weak absorption in the visible light region, potential matching with dye and TiO2 conducting band, and significant conversion efficiency.
