Problems solved by technology

However, after packaging, it must be thermosetting, because solar energy components need to operate under high temperature conditions, if it is thermoplastic, it will deform, and in severe cases, it will flow glue and lose its protective effect on silicon wafers.

Abstract

The invention relates to a high-effect solar cell back film which is formed by compounding the following two layers of materials: a modified high molecular weight high density polyethylene (HMWHDPE) film with the thickness of 0.08-0.10mm and a modified polyethylene terephthalate (PET) film with the thickness of 1.20-0.22mm. The high-effect solar cell back film is simple in production process and has good property, a solar cell panel packaged by the film can resist high-low temperature (-60 DEG C to 120 DEG C), can resist corrosion caused by water vapor and various corrosive gases and liquid, and dose not delaminate and chap, thereby achieving the standard of stable use for years.

Description

technical field [0001] The invention relates to a solar cell encapsulation film with high light transmittance. Background technique [0002] At present, solar cells are packaged with silicon wafers by means of two layers of polymer packaging films, and then bonded with upper and lower protective layer materials (glass and TPT film). For this reason, the encapsulation film must be transparent, and the light transmittance must be high, so as to ensure that the encapsulated solar cell module has sufficient photoelectric conversion efficiency; in addition, the adhesive force of the encapsulation film must be strong to better fix and Protect the solar cells; moreover, the packaging film must be soft and easy to change shape before curing and packaging, so that the solar cells can be packaged according to the shape of the solar cells without damaging the cells. However, after packaging, it must be thermosetting, because solar components must operate under high temperature conditi...
