Abstract
Provided is a semiconductor anode including: a metal oxide semiconductor formed on a conductive substrate; a dye formed on a surface of the metal oxide semiconductor; and a polymer self-assembled on a surface of the metal oxide semiconductor. Provided are also a dye-sensitized solar cell, a method of manufacturing the dye-sensitized solar cell, and a polymer composition used for the method of manufacturing the dye-sensitized solar cell. The dye-sensitized solar cell includes an organic material-incorporated metal oxide semiconductor. Therefore, the transfer of electrons in the semiconductor to an electrolyte can be prevented, thereby increasing photocurrent and photovoltage, resulting in enhancement in energy conversion efficiency.
