A solar cell includes a pair of electrodes, an electrolyte and a titanium dioxide layer. The electrolyte is positioned between the electrodes. The titanium dioxide layer is positioned between one of the electrodes and the electrolyte. Furthermore, the titanium dioxide layer has a rough surface opposite the electrolyte, and a range of ratios of oxygen ions to titanium ions is about 2~1.9 in the titanium dioxide layer.
