Problems solved by technology

[0008] However, in the structure disclosed in Patent Document 1, the current generated in the dye-sensitized solar cell needs to flow along the longitudinal direction of the slats in the conductive substrate included in the dye-sensitized solar cell. When the resistance value of the permanent substrate is high, and when the longitudinal dimension of the slab is long, the resistance loss of the current increases, and there is a problem that the power generation performance is lowered.
In addition, as in Patent Document 1, if the dye-sensitized solar cells are arranged on the slats in the exposed state, not only from the viewpoint of power generation performance but also from the viewpoints of durability and appearance, It is also difficult to say that it is suitable for practical use

Embodiment 1

[0152] In Example 1, a photoelectrode and a counter electrode were produced under the following conditions and procedures, a dye-sensitized solar cell was produced between these electrodes, and a pair of conductive layers were formed on one side. The base material is an embedded structure in which a dye-sensitized solar battery cell is inserted between the pair of base materials. In addition, in this example, as an example of the embedding structure of the dye-sensitized solar cell to which the present invention is applicable, a louver in which the dye-sensitized solar cell is embedded was produced.

[0153] (Production of photoelectrode)

[0154] First, as a conductive resin substrate, prepare a 15mm×214mm ITO (indium tin oxide)-PEN (polyethylene naphthalate) film material (sheet resistance: 15Ω / □), and use AD Titanium oxide particles described below were blown by the method to form a semiconductor layer. At this time, as film-forming conditions of the AD method, nitrogen w...

Embodiment 2

[0184] In Example 2, the dye-sensitized solar cell of the present invention was produced in the same procedure as in Example 1, except that aluminum was vapor-deposited as a conductive layer on one side of the pair of base materials of the slats to be a louver. An example of the embedded structure, that is, blinds, were evaluated in the same way. At this time, the film thickness of the conductive layer was adjusted so that the sheet resistance of the conductive layer was 3Ω / □.

Abstract

The present invention is an embedded structure for a dye-sensitized photovoltaic cell characterized in that: the structure possessed is such that a dye-sensitized photovoltaic cell having at least a photoelectrode and a facing electrode disposed so as to face the photoelectrode is interposed between a pair of substrates; an inner surface side of at least one of the pair of substrates is a conducting layer having conductivity; and the conducting layer is electrically connected with the photoelectrode or the facing electrode.

Description

technical field [0001] The present invention relates to an embedded structure of a dye-sensitized solar cell unit and a slat for a power-generating blind. [0002] This application claims priority based on Japanese Patent Application No. 2014-068327 for which it applied in Japan on March 28, 2014, and uses the content here. Background technique [0003] In recent years, solar cells have attracted attention as clean energy power generation devices that replace fossil fuels, and silicon-based solar cells, dye-sensitized solar cells, and organic thin-film solar cells have been developed. [0004] In particular, dye-sensitized solar cells have high photoelectric conversion efficiency and low cost, and are easy to mass-produce, so their structures and manufacturing methods are being extensively studied. In addition, the cost reduction of solar cells is actively progressing globally, and dye-sensitized solar cells are expected as next-generation solar cells. [0005] A dye-sensi...
