Dye-sensitized solar cell employing photoelectric transformation electrode and a method of manufacturing thereof

Abstract

A dye-sensitized solar cell with a photoelectric conversion electrode. The solar cell includes a semiconductor electrode, a counter electrode disposed opposite to the semiconductor electrode, an oxide semiconductor layer disposed between the semiconductor electrode and the counter electrode and having a dye adsorbed thereon, an electrolyte disposed between the semiconductor electrode and the counter electrode A solution, a spacer dividing a space defined between the semiconductor electrode and the counter electrode to form at least one unit cell, and a metal wire patterned at least partially between the at least one unit cell.

Description

[0001] priority statement [0002] This application claims priority to Korean Patent Application No. 10-2004-0049728 filed with the Korean Intellectual Property Office on Jun. 29, 2004, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to solar cells, and more particularly to dye-sensitized solar cells comprising transition metal oxide nanoparticle semiconductor electrodes. Specifically, the present invention relates to a dye-sensitized solar cell including a transition metal oxide nanoparticle semiconductor electrode, in which metal wires are provided in spaces between unit cells constituting a module, which increases the transfer of excited electrons into the semiconductor electrode. Transfer rate, and significantly reduce the reduction in photoelectric conversion efficiency that may be caused during the fabrication of large-scale modules, thereby increasing the photocurrent. Background technique [0004] Cur...
