Improved Dye-Sensitized Solar Cell (DSSC) for Higher Energy Conversion Efficiency
A dye-sensitized solar cell (DSSC) is provided. The DSSC anode includes a first electron-collecting layer deposited on a substrate and a first electron-transporting layer deposited on the first electron-collecting layer, the first electron-transporting layer containing light-absorbing dye. The DSSC anode also includes a second nanoporous electron-collecting layer deposited on the first electron-transporting layer; and a second electron-transporting layer deposited on the second porous electron-collecting layer, the second electron-transporting layer containing light-absorbing dye. Methods of fabricating the DSSC anode are also provided.
