Method for manufacturing dye-sensitized solar cell

Abstract

The present invention relates to a method of manufacturing a dye-sensitized solar cell having a new structure and, more particularly, to a method of manufacturing a dye-sensitized solar cell using an intermediate having an opening structure of a form in which a specific position between a transparent electrode and a counter electrode laminated is not sealed so that an internal space, formed by the two electrodes and a sealant, communicates with an outside. According to the present invention, there can be provided the method of manufacturing a dye-sensitized solar cell, which has advantages in that a process of manufacturing a solar cell can be shortened and the production cost can be reduced because holes for injecting an electrolyte needs not to be processed in manufacturing the dye-sensitized solar cell and the percent defective due to hole processing can be reduced in manufacturing the solar cell. Furthermore, according to the present invention, the dye-sensitized solar cell having a uniform thickness and surface can be manufactured because there is no change in the thickness of the solar cell which is generated when holes are closed after an electrolyte is injected.

Description

technical field [0001] The invention relates to a method for manufacturing a dye-sensitized solar cell, which can shorten the manufacturing process of the dye-sensitized solar cell, save production costs, and improve productivity. Background technique [0002] The depletion of fossil fuels, skyrocketing prices and dramatic changes in the Earth's climate require sustainable energy harvesting technologies. Among them, solar energy is inexhaustible and safe, so it has attracted much attention. [0003] In the past, silicon solar cells have been extensively studied and industrially applied, but there are problems of high unit price and low economic efficiency. Recently, as a new generation of solar cells, dye-sensitized solar cells (DSSC: Dye-Sensitized Solar Cell) have energy conversion efficiency second only to silicon solar cells and low production costs, and their research is in full swing. [0004] Generally speaking, DSSC consists of a semiconductor electrode (hereinafte...

Problems solved by technology

[0007] However, this electrolyte injection method adds a process for processing the injection hole. Therefore, there is not only a problem of an increase in the production unit price, but also, if figure 1 As shown, due to the injection of hole sealing material (17), the thickness of the solar cell itself increases, and the electrode surface is not uniform
