Transparent dielectric paste

Abstract

The invention discloses a transparent dielectric paste, comprising an organic carrier and inorganic glass powder dispersed in the organic carrier, wherein the mass ratio of the inorganic glass powder to the organic carrier is 60:40-90:10; the inorganic glass powder comprises PbO, B2O and SiO2 based on the mass ratio of 60-80:6-15:10-30; and the organic carrier comprises an organic solvent with the boiling point of 150-300 DEG C and a resin with the decomposition temperature of 200-350 DEG C, and the mass ratio of the organic solvent to the resin is 85:15-97:3. The transparent dielectric paste provided by the invention is formed by evenly dispersing the inorganic glass powder with insulating performance in an organic medium. The transparent dielectric paste can form a transparent dielectric layer which has high transmittance and surface flatness, proper thermal transition temperature and thermal expansion coefficient matched with substrate glass.

Description

technical field

[0001] The invention belongs to the technical field of dye-sensitized solar cells, in particular to a transparent medium paste for dye-sensitized solar cells. Background technique

[0002] Generally, solar cells are photovoltaic elements used to convert sunlight into electricity. Unlike other energy sources, solar cells can be used without limitation, are environmentally friendly, and thus are expected to gradually become an increasingly important energy source. In particular, it is expected that solar cells can not only be charged using sunlight, but also be mounted on various portable information devices such as portable computers, mobile phones, personal portable terminals, and the like.

[0003] Dye-sensitized nanocrystalline solar cells are a new generation of solar cells. In 1991, Gratzel M. published an article about dye-sensitized nanocrystal solar cells (Dye Sensitized SolarCells, referred to as DSSCs) in "Nature", which obtained a photoelectric co...
