Abstract
A dye-sensitized solar cell includes a negative electrode, a positive electrode, a photoelectrode mounted between the negative electrode and the positive electrode, and an electrolyte located between the photoelectrode and the positive electrode. The photoelectrode is adapted to absorb a dye. The photoelectrode includes a dense layer, a scattering layer and a carrier transport layer. The dense layer, the scattering layer and the carrier transport layer are stacked one upon another. The dense layer is formed by titanium dioxide nanoparticles having a diameter of 15-20 nm. The scattering layer is formed by titanium dioxide nanospheres having a diameter of 200-500 nm. The carrier transport layer is formed by titanium dioxide nanotubes having a length of 300-800 nm. Furthermore, a photoelectrode for the dye-sensitized solar cell, as well as a method for producing the photoelectrode, are also disclosed.
