METHOD OF MANUFACTURING DYE-SENSITIZED SOLAR CELL HAVING LIGHT ABSORPTION INCREASE MEANS AND THE SOLAR CELL

摘要

A dye-sensitized solar cell is provided. The solar cell includes a transparent substrate; a conductive transparent electrode formed on a surface of the transparent substrate; a metal oxide particle electrode layer in which a photosensitive dye capable of absorbing light is adsorbed; a counter electrode, and an electrolyte injected between the metal oxide particle electrode layer and the counter electrode. The metal oxide particle electrode layer comprises a first electrode layer comprising metal oxide particles and having a predetermined pattern formed thereon and a second electrode layer comprising metal oxide particles and formed on the first electrode layer. Refractive indexes of the first and second electrode layers are different from each other.

1. A method of manufacturing a dye-sensitized solar cell, comprising steps of:
providing a transparent substrate; forming a conductive transparent electrode on a surface of the transparent substrate; forming an electrode layer capable of adsorbing a photosensitive dye, wherein a first electrode layer comprising metal oxide particles is formed on the transparent electrode and is imprinted using a mold having a predetermined pattern to thus form a pattern corresponding to the pattern of the mold on the first electrode layer, and a second electrode layer comprising metal oxide particles is formed on the first electrode layer having the pattern to thus form the electrode layer comprising the first electrode layer and the second electrode layer, refractive indexes of the first electrode layer and the second electrode layer being made to be different; dipping the substrate into a solution comprising a photosensitive dye capable of absorbing light, thereby adsorbing the dye in the electrode layer, and injecting a liquid electrolyte between the electrode layer and a counter electrode.
