Description
The present invention relates to a dye-sensitized solar cell, and more particularly, to a dye-sensitized solar cell, in which a grid electrode is composed of a plurality of unit grid electrodes and an encapsulant is provided around each unit grid electrode, And more particularly to a dye-sensitized solar cell capable of improving the cohesion strength between the upper transparent substrate and the lower transparent substrate by reducing the possibility and increasing the sealing area.
A dye-sensitized solar cell is a device that applies the principle of photosynthesis of a plant. It is a case where a dye having a function of absorbing light energy from a chloroplast is combined with a polymer and applied to a solar cell. The dye-sensitized solar cell is based on a dye polymer for solar absorption, a semiconductor oxide serving as an n-type semiconductor, an electrolyte acting as a p-type semiconductor, a counter electrode for a catalyst, and a transparent electrode for solar transmission.
The dye-sensitized solar cell basically has a structure in which two transparent substrates are coalesced (Korean Unexamined Patent Publication No. 1437578). A counter electrode for electrolyte reduction is provided on each of the transparent substrates, and an electrolyte is filled between the two transparent substrates.
In the case of the dye-sensitized solar cell of the tandem type, as shown in FIG. 1, a plurality of unit cell regions are provided, a
In the conventional tandem dye-sensitized solar cell, if the state of the transparent substrate is locally defective, the electrolyte inside each unit cell flows to the area where the grid electrode is provided, and the grid electrode is corroded This problem is caused by the adhesion strength of the transparent substrate.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems as described above, and it is an object of the present invention to provide a plasma display panel in which grid electrodes are composed of a plurality of unit grid electrodes and sealing material is provided around each unit grid electrode, And to improve the adhesion strength between the upper transparent substrate and the lower transparent substrate by increasing the area of the encapsulation material and the dye-sensitized solar cell.
According to an aspect of the present invention, there is provided a dye-sensitized solar cell including an upper transparent substrate and a lower transparent substrate, the upper transparent substrate and the lower transparent substrate being bonded together via an encapsulant, And a counter electrode is provided in each unit cell region of the lower transparent substrate, and each of the upper transparent substrate and the lower transparent substrate is divided into a cell region, A grid electrode is provided in the cell region, a grid electrode provided in each cell region is composed of a plurality of unit grid electrodes, and each unit grid electrode is spatially separated by an encapsulating material.
An encapsulant is provided around each of the unit grid electrodes.
The dye-sensitized solar cell according to the present invention has the following effects.
The grid electrodes are subdivided into a plurality of unit grid electrodes and each unit grid electrode is surrounded by an encapsulating material, thereby minimizing the deterioration of electrical characteristics of the grid electrode due to electrolyte penetration. At the same time, the adhesion strength of the solar cell can be improved by increasing the contact area of the sealing material.
