Abstract
(EN)
The present invention relates to a photoelectrode for dye-sensitized solar cell, a preparing method of the same, and a dye-sensitized solar cell having the same. The method includes: manufacturing of colloidal solution through the self-assembly; forming a layer of a porous transition metal oxide by measures such as a heat treatment, after forming a synthetic colloidal crystal on a transparent conductive substrate and injecting a transition metal oxide precursor solution; and forming a structure of the porous transition metal oxide and adsorbing photosensitive dye by post-processing with precursor solution which includes transition metal oxide. According to the present invention, controlling the size of pores and the thickness of the photoelectrode is possible and, in particular, with the post treatment, electrons can be moved easily, by enlarging a specific surface area and increasing the thickness, thereby improving the efficiency of the dye-sensitized solar cell using the photoelectrode.
