Problems solved by technology

However, liquid electrolytes have problems such as low boiling point, easy volatility, high fluidity, easy leakage, and poor stability.
Solid electrolytes can avoid these disadvantages, but they also have disadvantages such as low electrical conductivity resulting in relatively low photoconversion efficiency and poor interfacial wettability between the electrolyte and the electrode.

Abstract

The invention discloses a preparation method of a dye-sensitized solar photovoltaic panel. Firstly, ethylene carbonate, propylene carbonate and N-methylpyrrolidone are mixed with a mass ratio of 2 to 6:1 to 5:1 to 3, and stirred. After uniformity as a solvent, add iodine compound and iodine simple substance, and continue to stir; then add a gel agent with a mass fraction of 8% to 15%, and stir at 80°C for 2 to 5 hours until a uniform solution is formed to obtain a gel polymer electrolyte; finally, the The gel polymer electrolyte is coated on the titanium dioxide photoanode film sensitized in the dye solution, and then the platinum counter electrode is covered on the surface of the gel polymer electrolyte to obtain a dye-sensitized solar photovoltaic panel. The solar photoelectric panel prepared by the invention has high photoelectric conversion efficiency, good mechanical strength and photoelectric stability, long service life, simple preparation process and low cost, and is beneficial to industrialized production.

Description

technical field [0001] The invention relates to the field of photoelectric conversion and new energy, in particular to a preparation method of a dye-sensitized solar photovoltaic panel. Background technique [0002] At present, the development and utilization of new energy is a major issue that countries must first solve. Among many new energy sources, solar energy has attracted widespread attention due to its abundant reserves, clean and pollution-free, and small geographical restrictions. Solar photovoltaic panels can use the photovoltaic effect to directly convert the sun's light into electrical energy for use. Solar photovoltaic panels are mainly based on semiconductor materials. According to the different materials used, they can be divided into silicon-based, multi-component compound films, organic and fuel-sensitized types. Among them, dye-sensitized solar photovoltaic panels have become a hotspot in the research of the new generation of Tianyang solar photovoltaic ...
