Abstract

Disclosed is a dye-sensitized solar cell module and a method of manufacturing the same. More specifically a counter electrode has connection parts formed within the side surfaces of the transparent conductive substrates. Edges of the working electrode and the counter electrode are bonded with each other by a sealant along the outer peripheral except for at one or more portions of the edges to form an electrolyte injection port. An electrolyte is then injected through the electrolyte injection hole into a space between the working electrode and the counter electrode. The electrolyte injection hole is then sealed by a sealant.

First claim

What is claimed is:

1. A dye-sensitized solar cell module, the dye-sensitized solar cell module comprising:
a working electrode including a first collector and a photo-electrode to which a dye is adsorbed on a first transparent conductive substrate;
a counter electrode including a second collector and a catalytic electrode on a second transparent conductive substrate;
an electrolyte injected into a space between the working electrode and the counter electrode;
wherein the first collector includes a first collector part disposed on a first surface of the first transparent conductive substrate, the first surface of the first transparent conductive substrate facing the second transparent conductive substrate and a first connection part extending from the first collector part, the first connection part extending along a side surface of the first transparent conductive substrate,
wherein the second collector includes a second collector part disposed on a first surface of the second transparent conductive substrate, the first surface of the second transparent conductive substrate facing the first transparent conductive substrate and a second connection part extending from the second collector part, the second connection part extending along a side surface of the second transparent conductive substrate,
wherein the length of the first connection part extending along the side surface of the first transparent conductive substrate is about 50% to 80% of a thickness of the side surface of the first transparent conductive substrate and the length of the second connection part extending along the side surface of the second transparent conductive substrate is about 50% to 80% of a thickness of the side surface of the second transparent conductive substrate,
wherein a first electrolyte injection port is formed at a corner of one side of the dye-sensitized solar cell module and a second electrolyte injection port is formed at a corner of an opposite side of the dye-sensitized solar cell, wherein the first electrolyte injection port and the second electrolyte injection port are arranged in diagonally opposite positions and
wherein a first sealant is formed along outer edges of the working electrode and the counter electrode except for at the first electrolyte injection port and the second electrolyte injection port, and a second sealant is formed at the first electrolyte injection port and second electrolyte injection port.

2. A dye-sensitized solar cell panel comprising a plurality of the dye-sensitized solar cell modules of claim 1
wherein the plurality of the dye-sensitized solar cell modules are arranged on a plane and the first and second connection parts of adjacent dye-sensitized solar cell modules of the plurality of dye-sensitized solar cell modules are connected to each other.
