Description

Window screen using solar cell {Window screen frame using solar cell}

The present invention relates to an insect screen window using a solar cell, and more particularly to an insect screen window using a solar cell provided with a frame on which the dye-sensitized solar cell can be effectively installed on the front of the window is installed.

Solar cells are devices that turn solar energy into electrical energy, including silicon, dye-sensitized solar cells, and thin-film solar cells. A double dye-sensitized solar cell has been studied in the field since the development of a dye-sensitized nanoparticle titanium dioxide solar cell by Michael Gratzel of the Swiss National Institute of Advanced Industrial Science and Technology (EPFL) in 1991. Dye-sensitized solar cells have the potential to replace existing amorphous silicon solar cells because they have a significantly lower manufacturing cost than conventional silicon solar cells. Unlike silicon solar cells, dye-sensitized solar cells absorb visible light, - a dye molecule capable of forming a hole pair, and a transition metal oxide that transfers generated electrons as main constituent materials.

The unit cell structure of a general dye-sensitized solar cell is based on a conductive transparent electrode composed of an upper and a lower transparent substrate (generally glass) and a transparent conductive oxide (TCO) formed on the surface of the transparent substrate, On the other side of the conductive transparent electrode corresponding to the second electrode (catalytic electrode), a porous metal oxide layer having a dye adsorbed on the surface thereof is formed, and on the other conductive transparent electrode corresponding to the second electrode Pt), and the transition metal oxide, for example, TiO 2, and the porous electrode and the catalyst thin film electrode are filled with an electrolyte. That is, the dye-sensitized solar cell is an electrolyte that supplies electrons to an oxidized dye between a working electrode substrate coated with a working electrode (TiO2) material coated with a dye, which generates light by receiving light, and a catalytic electrode substrate supplying electrons .

For the practical use of such a dye-sensitized solar cell, it is necessary to realize a module having no reduction in efficiency even in a large area. For this purpose, there is a method of transporting electrons through a metal grid made of metal such as silver.

That is, in the case of a large-area submodule, an electron movement distance in a substrate having a relatively large resistance value is increased due to an increase in the cell area, resulting in reduction in efficiency due to long-distance movement of electrons. In order to maximize the power generation efficiency by optimizing the working electrode substrate and the catalyst electrode substrate through the introduction of these collecting grid electrodes, the collecting grid is disposed inside the cell to reduce the moving distance in the substrate by reducing the resistance, And the introduction of such a collecting grid electrode is simple in the process, and is easy to be applied to the large-scale application.

Referring to FIG. 17, a conductive adhesive 621 is applied to the inside of the groove 620 of the cassette 610, and the dye-sensitized solar cell 630 is fixed by using the conductive adhesive 621. In one embodiment of the present invention, the conductive adhesive 620 may include polyimide or conductive epoxy, but the scope of the present invention is not limited thereto. The conductive adhesive 621 electrically connects both sides of the line-shaped conductive member 622 and the substrate having the long width among the dye-sensitized solar cell substrate.

Another embodiment of the present invention mechanically secures the dye-sensitized solar cell to the cassette by using a rotating member provided outside the groove of the cassette support instead of the conductive adhesive.

18 and 19 are cross-sectional views and plan views illustrating a dye-sensitized solar cell fixing method according to another embodiment of the present invention.

Referring to FIG. 18, a rotatable member 730 having a predetermined depth may be rotatable outside the groove 720 of the second frame 710. The rotating member 730 exposes the entire groove according to the rotation angle, the exposed groove 720 has a substrate having a long width as shown in Figure 3, asymmetric substrate type dye-sensitized solar cell 740 ) Is inserted (see solid line). Thereafter, the bar-shaped rotating member 730 rotates, and the rotated rotating member 730 prevents the inserted dye-sensitized solar cell 740 from being detached from the groove (see dotted line).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Modification is possible. Accordingly, the spirit of the present invention should be understood only in accordance with the following claims, and all of the equivalent or equivalent variations will fall within the scope of the present invention.
