Abstract

The invention discloses a quasi solid electrolyte for a dye sensitization solar cell. The compositions by weight percentage of the electrolyte are: 5-20 percent of alpha- cyanoacrylate, 0.1-1 percent of a crosslinking agent, 10-20 percent of iodine salt, 0.5-3 percent of iodine, 1-10 percent of a modifier, 40-60 percent of a plasticizer, and 10-20 percent of an organic solvent. A preparation method comprises the following steps of: stirring and mixing the compositions evenly according to the proportion to generate homogeneous phase liquid; then dripping the homogeneous phase liquid onto a TiO2 film electrode for absorbing dye; and thermosetting and drying evaporating the organic solvent to obtain the quasi solid electrolyte for the dye sensitization solar cell. The quasi solid electrolyte is characterized by low cost, simple preparation process, a high curing rate, easy realization of industrialized production, high ionic conductivity, good thermal stability and mechanical properties, etc.

Description

technical field

[0001] The invention relates to a quasi-solid electrolyte and a preparation method thereof, in particular to a quasi-solid electrolyte for dye-sensitized solar cells and a preparation method thereof. Background technique

[0002] At present, monocrystalline silicon cells dominate the solar cell market. As the latest achievement in the development of solar cells in recent years, dye-sensitized energy cells (DSSC) show a new development direction of solar cells. 1991 Switzerland et al. using bipyridyl ruthenium complex dyes and nanoporous TiO 2 Dye-sensitized solar cells are prepared from thin films. This type of solar cells is mainly composed of transparent conductive glass, nano-TiO 2 It is composed of porous semiconductor film, dye photosensitizer, electrolyte and counter electrode. Compared with the expensive production cost and complicated preparation process of silicon solar cells that currently dominate the market, the most attractive features of thi...
