Energetically Graded Band structure of Metal doped TiO2 Photo-electrode Enhances the Electron Correcting Efficiency and Reduces the Recombination rate constants in DSSCs |
초록 |
The novel concept of introducing cascade structure into the photo-anode network with Metal-doped photo-electrode in dye-sensitized solar cells (DSSCs) such as W and Mo is proposed to increase the power conversion efficiency. An improvement in the device performance was obtained when layered metal-doped TiO2 films graded band structure were applied as the photo-anode of DSSCs. DSSCs containing the graded band structure engineered photo-electrode exhibited the significant enhanced photocurrent density and photovoltaic performance without decreasing the VOC, which is 50 % higher than basic DSSCs without a blocking layer. These findings suggest an innovative route toward the harvesting solar energy by enhancing the carrier charge transfer rate. |
