Electrode of dye-sensitized solar cell and method for manufacturing the same

Abstract

Disclosed is a method for manufacturing an electrode for a dye-sensitized solar cell, the method comprising: (a) forming a precursor layer on a conductive substrate using a first suspension in which TTIP (Titanium Tetra-IsoPropoxide) is dispersed; and (b) forming a metal oxide layer on the precursor layer using electrophoretic deposition, wherein the (b) includes: preparing a second suspension in which titanium dioxide (TiO2) is dispersed; and immersing a first electrode as the conductive substrate and a second electrode as a counter electrode to the first electrode into the second suspension, and applying power to the first and second electrodes, wherein the second suspension contains a polyethylenimine (PEI) solution to increase electrical conductivity via a mutual reaction between the titanium dioxide (TiO2) and the precursor layer. Therefore, a highly efficient electrode may be manufactured in a low temperature process of 100° C. or lower via a combination of the precursor layer and the PEI.
