在染料敏化太阳能电池(DSCs)替代光阳极材料的研究中，关于WO(3)的报道很少，这可能是因为WO(3)的表面酸性，与TiO(2)和ZnO相比，其导带边缘位置更正(Vs NHE)。首次成功地制备了基于多孔WO(3)纳米颗粒薄膜的染料敏化太阳能电池，效率高达0.75%。用拉曼光谱和X射线衍射仪分析了WO(3)的多晶结构。结果表明，用TiCl4处理WO(3)纳米颗粒薄膜能显著提高其性能，TiCl4处理的WO(3)DSCs的效率可达1.46%。
In research on alternative photoanode materials for dye-sensitized solar cells (DSCs), there is rarely any report on WO(3), probably due to its acidic surface and more positive (vs NHE) conduction band edge position compared to TiO(2) and ZnO. For the first time, dye-sensitized solar cells based on porous WO(3) nanoparticle films were successfully fabricated with efficiency of up to 0.75%. The multicrystalline structure of WO(3) was examined by Raman spectroscopy and X-ray diffraction analysis. It was found that significant performance enhancement can be obtained from treating the WO(3) nanoparticle film with TiCl(4); the TiCl(4)-treated WO(3) DSCs were recorded with efficiency reaching 1.46%.
