文摘

In research on alternative photoanode materials for dye-sensitized solar cells (DSCs), there is rarely any report on WO₃, probably due to its acidic surface and more positive (vs NHE) conduction band edge position compared to TiO₂ and ZnO. For the first time, dye-sensitized solar cells based on porous WO₃ nanoparticle films were successfully fabricated with efficiency of up to 0.75%. The multicrystalline structure of WO₃ was examined by Raman spectroscopy and X-ray diffraction analysis. It was found that significant performance enhancement can be obtained from treating the WO₃ nanoparticle film with TiCl₄; the TiCl₄-treated WO₃ DSCs were recorded with efficiency reaching 1.46%.
