Abstract
Description
The present invention relates to a dye-sensitized solar cell assembly using a conductive block, and more particularly, to an electrical coupling efficiency between unit dye-sensitized solar cell modules by using a conductive block that can be height-adjusted between unit dye-sensitized solar cell modules. And a dye-sensitized solar cell assembly that can be effectively coupled to a glass assembly.
Much research has been done in this area since the development of dye-sensitized nanoparticle titanium dioxide solar cells by Michael Gratzel of the Swiss National Lozan Institute for 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,
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.
