Metallic flexible dye-sensitized solar cell and manufacturing method thereof

Abstract

The present invention relates to a dye-sensitized solar cell, and in particular to a metal flexible dye-sensitized solar cell. In the cell, silver is coated or deposited on the front side of a polymer plastic substrate, patterned using laser or thermal embossing, and coated on it. Or after depositing the protective film, a barrier layer coated with a carbon film or Al2O3 is coated on the back of the polymer plastic substrate to produce an upper electrode substrate; a stainless steel film is coated on the front of the polymer plastic substrate and then coated on it. Coating the metal layer, so that after applying the flexible metal substrate in a manner that it can be applied in the form of a flexible film, the metal layer is coated with titanium dioxide, SiO2 or a transparent carbon film, and a TiO2 nanoparticle layer is coated on it, Then, colored organic dyes and colored inorganic dyes are used to make the lower electrode substrate; after injecting electrolyte between the upper electrode substrate and the lower electrode substrate, double sealing is performed with a sealing material, and then sealed with ethylene / vinyl acetate copolymer.

AI Technical Summary

Problems solved by technology

[0014] Recently, an inorganic oxide layer that can be sintered at a low temperature (approximately less than 150°C) has been developed, and a commercially available conductive plastic substrate can be used, but in this case, it is necessary to accept a decrease in photoelectric conversion efficiency

In addition, additional efficiency reduction can be expected due to the lower transmittance and conductivity characteristics of the transparent upper electrode substrate compared to the ITO substrate

Therefore, it is quite difficult to realize flexible dye-sensitized solar cells with high efficiency

[0015] In addition, although such a conventional flexible dye-sensitized solar cell is injected with a liquid electrolyte, etc., there are problems such as unstable service life due to electrolyte leakage phenomenon in which the injected liquid electrolyte leaks over time.
