Abstract

The invention relates to an epoxy resin-base paint for flexible or thin-film solar cells and a preparation method thereof. The paint is prepared from the following components in percentage by mass: 8-12% of epoxy resin solution (the solid content of epoxy resin is 1-10%), 0.0001-0.1% of nano aluminum powder, 0.1-1% of viscosity regulator and the balance of solvent. The product can be applied to the upper surface of the flexible or thin-film solar cell by a spray coating, silk screen printing, printing or any other technique to directly enhance the generating efficiency of the flexible or thin-film solar cell.

Description

technical field [0001] The invention relates to a coating for flexible or thin-film solar cells and a preparation method thereof. By using the coating to form a light-transmitting coating on the surface of the light-incident surface of the flexible or thin-film solar cells, the efficiency of the flexible or thin-film solar cells can be directly improved. Background technique [0002] All polymer compounds containing epoxy groups in their molecular structure are collectively referred to as epoxy resins. The cured epoxy resin has good physical and chemical properties. It has excellent bonding strength to the surface of metal and non-metal materials, good dielectric properties, small shrinkage rate, good dimensional stability and high hardness. It has good flexibility and is stable to alkali and most solvents, so it is widely used in various sectors of national defense and national economy for casting, impregnating, laminating, adhesive, coating and other purposes. As far as e...
