Embodiment 1

[0038] The preparation of embodiment 1 precursor

[0039] The preparation method of ultraviolet curing electrolyte precursor A is: the following raw materials are calculated by mass parts, 160 parts of 2-phenoxymethyl oxirane, 36 parts of acrylic acid, 5 parts of 12-(dimethylamino) ethyl acrylate 1. Heat 1 part of hydroquinone monomethyl ether at 100° C. for 5 hours, and then add 2% benzoin butyl ether based on the total amount of the above-mentioned raw materials to obtain a UV-curable electrolyte precursor.

Embodiment 2

[0041] 1) Preparation of dye sensitizer solution: weigh 40 mg of compound N719 (cis-bis(isothiocyanato)bis(2,2-bipyridyl-4,4-dicarboxylato)-ruthenium(II)bis-tetrabutylammonium, Provided by Solaronix), add solvent ethanol to the mark;

[0042] 2) Cleaning of the substrate: The conductive substrate is ultrasonically cleaned with detergent, secondary water, acetone and ethanol in sequence, dried under hot air flow, and set aside.

Abstract

The present invention discloses a preparation method for a UV-curable electrolyte and an application thereof in a solar cell, and belongs to the technical field of solar cells. The preparation method of the electrolyte is as follows: adding iodine, lithium iodide, urea and 4-tert-butylpyridine (TBP) into a precursor of the UV-curable electrolyte, and stirring the mixture uniformly in the dark. The electrolyte can be cured and encapsulated with the only need for illumination of an UV lamp, and a step of hot pressing is omitted, so that the step of preparation of a dye sensitized solar cell is simpler and the condition of the same is more moderate, thereby not only saving energy but also avoiding evaporation and leakage of liquid electrolytes and greatly improving stability of photoelectric devices.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and relates to a method for preparing an ultraviolet light curing electrolyte. Background technique [0002] With the depletion of mineral resources such as coal, oil and natural gas, energy crisis and environmental pollution have become serious problems that need to be solved urgently. How to effectively use renewable energy technology has become a major topic all over the world. Dye-sensitized solar cells (B.O'Regan, M. Nature, 1991, 353, 737-740), because of its simple manufacturing process, low cost, high photoelectric conversion efficiency and other advantages, it has potential practical value. [0003] Dye-sensitized solar cells (DSSCs) are usually composed of semiconductor oxide nanoporous membranes, dye sensitizers, redox electrolytes, and Pt electrodes. However, the traditional liquid redox electrolyte is volatile, easy to leak, and corrodes the counter electrode. For this reason...
