Problems solved by technology

[0005] However, when aliphatic diamines or polyamines are used as adhesion promoters for high-temperature lamination, the fluoropolymer layer will cause yellowing phenomenon (yellowing phenomenon), which in turn makes the fluoropolymer layer easy to peel off.

[0037] Please refer to Table 1, take the adhesion-promoting layer of Examples 1-5 in Table 1, dissolve the material of the adhesion-promoting layer in methanol, and prepare methanol solutions of various concentrations, and then apply the solution on a surface of 10cm×10cm with a scraper. On the fluoropolymer substrate (the production of the fluoropolymer substrate is to coat a layer of 20 μm fluorosilicone polymer / TiO on a 188 μm PET substrate 2 layer). (Represents fluorosiloxane polymer material mixed with 15wt% TiO 2 Inorganic materials, fluorosilicone polymers have a weight average molecular weight of about 10,000 g / mol).

[0038] Afterwards, place the substrate in an oven at 40°C for 30 minutes to remove the solvent, then place EVA (400-600 μm, model RC02B (product of Mitsui Chemicals)) on the above-mentioned substrate, and conduct a high-temperature process at 150°C and a pressure of 100Kpa. Pressing for 30 minutes or 1 hour, release the pressure after completion and wa...

Abstract

The disclosure provides a multilayer composition containing fluoropolymer and method for fabricating the same, and a solar cell module. The multilayer composition includes: a fluoropolymer layer; a non-fluorinated polymer layer; and an adhesion promoter layer formed between the fluoropolymer layer and the non-fluorinated polymer layer, wherein the adhesion promoter layer includes aromatic diamines or aromatic polyamines.

Description

【Technical field】 [0001] The present invention relates to a multilayer composition, and in particular to a multilayer composition of fluoropolymers. 【Background technique】 [0002] In recent years, due to the impact of global climate change, environmental pollution and resource shortage, the rising awareness of environmental protection and the warning of energy crisis have stimulated the vigorous development of the photovoltaic industry. [0003] The solar cell module includes a front sheet, a solar cell, an encapsulation material and a back sheet. The backsheet is generally composed of multiple layers of materials, such as polyethylene terephthalate (PET) as the base material, and then coated with a fluoropolymer layer. Afterwards, the fluoropolymer layer is bonded to an encapsulation material such as ethylene vinyl acetate copolymer (EVA). However, the adhesion between the fluoropolymer and the EVA material is poor. [0004] US 6074719 provides a multi-layer composition ...
