In order to improve the power conversion efficiency(PCE)of a dye sensitized solar cells(DSSCs),it is important to adsorb the dye molecule uniformly within the whole negative electrode material,such as titanium dioxide(TiO2)thin films.Although generally,dye molecules are adsorbed by soaking a TiO2 thin film in the dye solution,the optimal adsorption time is extremely long.On the other hand,the adsorption time to adsorb a specified amount of the dye was drastically shortened by using electrophoresis(EP).
