Embodiment 1

[0219] First, a laminated body formed by forming a transparent conductive film made of FTO with a thickness of 1 μm on a transparent substrate made of glass with a thickness of 1 mm was prepared. Next, if image 3 shown, using CO 2 Grooves 90 are formed in the transparent conductive film 12 using a laser (V-460 manufactured by Universal Systems Co., Ltd.), and transparent conductive films 12A to 12F are formed. At this time, the width of the groove 90 was 1 mm. In addition, each of the transparent conductive films 12A to 12C is formed to have a quadrangular main body of 4.6 cm×2.0 cm and a protrusion protruding from one side edge of the main body. In addition, the transparent conductive film 12D is formed to have a quadrangular main body of 4.6 cm×2.1 cm, and a protrusion protruding from one side edge of the main body. In addition, among the transparent conductive films 12A to 12D, the protruding portions 12c of the three transparent conductive films 12A to 12C are composed...

Embodiment 2

[0248] A DSC module was produced in the same manner as in Example 1 except that the first current collector wiring 17 was not formed.

Embodiment 3

[0250] A DSC module was produced in the same manner as in Example 1 except that the connecting portion 14 was not formed.

Abstract

This dye-sensitized solar cell element for low luminance comprises: at least one dye-sensitized solar cell; a first current drawing part for drawing an electric current from at least one dye-sensitized solar cell; and a second current drawing part for drawing an electric current from at least one dye-sensitized solar cell. Each dye-sensitized solar cell is provided with: a first electrode which has a transparent substrate and a transparent conductive film that is provided on the transparent substrate; a second electrode which faces the first electrode and has a metal substrate; an oxide semiconductor layer which is provided on the first electrode or on the second electrode; and an annular sealing part which joins the first electrode and the second electrode with each other. The first current drawing part is contained in the transparent conductive film of one dye-sensitized solar cell among the at least one dye-sensitized solar cell. The second current drawing part is electrically connected to the metal substrate of the second electrode of one dye-sensitized solar cell among the at least one dye-sensitized solar cell. The first current drawing part and the second current drawing part are arranged to be adjacent to each other.

Description

technical field [0001] The present invention relates to a dye-sensitized solar cell element for low illumination. Background technique [0002] As photoelectric conversion elements, attention has been paid to dye-sensitized solar cell elements from the viewpoint of obtaining inexpensive photoelectric conversion elements with high photoelectric conversion efficiency, and various developments have been made for dye-sensitized solar cell elements. [0003] A dye-sensitized solar cell element generally includes at least one dye-sensitized solar cell, and each dye-sensitized solar cell includes a working electrode, a counter electrode, and an annular sealing portion that connects the working electrode and the counter electrode. Also, the working electrode has a transparent substrate, a transparent conductive film formed thereon, and an oxide semiconductor layer provided on the transparent conductive film. [0004] As such a dye-sensitized solar cell element, for example, an elem...
