Embodiment 1

[0068] (1) Manufacture of working electrode

[0069] After preparing the FTO glass substrate, the titanium dioxide (TiO 2 ) coating composition coated on top of the transparent conductive oxide layer of the substrate, followed by heat treatment at 520° C. for 40 minutes to achieve contact and filling between nanometer-sized metal oxides, thereby producing a thickness of about 7μm nano-oxide layer. Use 3M Scotch Magic Tape as a spacer to adjust thickness. Thereafter, the same coating composition was coated on top of the nano-oxide layer by the same method, followed by heat treatment at 520° C. for 40 minutes, thereby manufacturing a nano-oxide layer with a thickness of about 15 μm. Then, a dye solution was prepared using N-719 dye from Solaronix and ethanol, wherein the substrate formed with the nano-oxide layer thereon was immersed for 48 hours, and then the substrate was dried to allow the nano-sized metal oxide to absorb the dye, Thus, a negative electrode is produced. ...

Embodiment 2

[0084]Using the same method as in Example 1, the difference is that 100 parts by weight of bisphenol A liquid epoxy resin (YD 128 from Toto Kasei Co., Ltd.) is used instead of cresol novolac epoxy in the preparation of the polymer electrolyte resin.

Abstract

The present invention relates to a polymer electrolyte for dye-sensitized solar cells and a fabrication method of dye-sensitized solar cells using the polymer electrolyte. More specifically, the present invention relates to an excellent polymer electrolyte for dye-sensitized solar cells, which is not only capable of virtually preventing a leakage, the worst disadvantage of dye-sensitized solar cells using a conventional liquid electrolyte, but exhibiting a light conversion efficiency relatively higher than those of the conventional polymer electrolytes and being applicable to fabrication processes of large area dye-sensitized solar cells or flexible dye-sensitized solar cells; and a fabrication method of dye-sensitized solar cells using such a polymer electrolyte. To this end, the polymer electrolyte for dye-sensitized solar cells according to the present invention comprises a thermosetting epoxy resin, an imidazole-based curing accelerator and a metallic salt. The fabrication method of dye-sensitized solar cells according to the present invention makes use of said polymer electrolyte for dye-sensitized solar cells as an adhesive between a working electrode and a counterelectrode thereof, while maintaining the final junction state in the solid phase.

Description

technical field [0001] The present invention generally relates to a polymer electrolyte for a dye-sensitized solar cell and a method for manufacturing a dye-sensitized solar cell module using the same, and more particularly, the present invention relates to a Polymer electrolyte for a dye-sensitized solar cell having solar energy conversion efficiency and being suitable for a process for manufacturing a dye-sensitized solar cell or a flexible dye-sensitized solar cell having a large surface area and a method for manufacturing a dye-sensitized solar cell module using the same, The aforementioned leakage is one of the worst drawbacks in conventional dye-sensitized solar cells using liquid electrolytes. Background technique [0002] Recently, due to investments in alternative energy industries and green growth policies worldwide, the photovoltaic cell or solar cell market is rapidly growing, and thus the production of solar cell modules is expected to increase at a rate of more...
