제목 Effect of w-doped TiO2 layer on the charge collection efficiency in dye-sensitized solar cells
초록 The transportation of photo-generated electron in dye sensitized solar cells (DSSCs) is one of the most important criteria to enhance their overall power conversion efficiency. The photo-generated electron is injected from the lowest unoccupied molecular orbital of photosensitizer into the conduction band level of TiO2, and then transferred to the conductive transparent electrode. In this work, W-doped TiO2 is introduced as blocking layer with various amount of tungsten dopant. The conduction band of W-doped TiO2 moves toward lower energy level with the increase in the amount of W dopant. The downshift of blocking layer conduction band can accelerate the transport rate of photo-generated electron.
