Enhanced Electron Diffusion Length and Correcting efficiency in the photo anode containing Mo-doped TiO2 blocking Layers in DSSCs |
| 초록 |
The power conversion efficiency of dye-sensitized solar cells has been limited because electron transport is not fully achieved, and the injected electrons always recombine with the acceptor species before the electrode can collect them. The concept of introducing metal-doped TiO2 blocking layer into the mesoporous TiO2 network of dye-sensitized solar cells is proposed to enhance the power conversion efficiency. DSSCs based on Mo-TiO2 blocking layer show an advantage in increasing he charge transport. The charge transfer resistance in DSSC is significantly suppressed by the Mo-doping. As a result of the downward shifted conduction band and increased charge transport, the photocurrent density of the device is improved remarkably with an almost unchanged photovoltage. The highest power conversion efficiency (η = 8.03%) is obtained at 4% Mo-doping, which shows increases by 13% in Jsc and by 7% in η, as compared with the undoped DSSC. |
