<P>PROBLEM TO BE SOLVED: To provide a coating agent to obtain a thick and porous semiconductor electrode film having high light transmittance, a substrate with the semiconductor electrode film having high light transmittance, and a highly efficient dye-sensitized solar battery. <P>SOLUTION: This coating agent is to form a semiconductor electrode on a substrate. This coating agent has a semiconductor particulate with a particle diameter of 1-100 nm, and its viscosity is 0.5-100 Pas. This coating agent has a thickener, and the thickener is 2-20 times as much as the semiconductor particulate by weight ratio. The substrate with the semiconductor electrode film and the dye-sensitized solar battery can be obtained by using the coating agent. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
