Abstract

The invention discloses a preparation method of a peel strength test sample and the peel strength test sample. A glass substrate, a spacer, a first PVB plate and a metal back plate are sequentially stacked; wherein the length of the spacer is smaller than that of the glass substrate, and the length of the first PVB plate is larger than that of the spacer; and laminating and fixing, and extracting the spacer to obtain the peel strength preparation sample piece. Therefore, the second PVB plate, the metal back plate, the first PVB plate, the isolation sheet and the glass substrate are packaged, on one hand, a peeling strength test does not need to be carried out by adopting a finished photovoltaic module, the test cost can be reduced, the test period can be shortened, photovoltaic module manufacturers can conveniently adjust lamination parameters in time, and the production efficiency and the production utilization rate are improved; and on the other hand, related data of the glass strength test can be obtained without a falling ball experiment and a shotgun shot experiment of the PVB packaged photovoltaic module, and the experiment safety of the glass strength test can be improved.

Description

technical field [0001] The invention relates to the technical field of peel strength testing of photovoltaic modules, in particular to a method for preparing a peel strength test sample and the peel strength test sample. Background technique [0002] The adhesion between the packaging film of photovoltaic modules and glass is an important indicator of product performance, which directly determines the safe use and long-term performance of the product. It is generally characterized by the peel strength of the glass and packaging film by tensile testing. [0003] Due to the high elasticity of the encapsulation film after lamination, the encapsulation film has a large extension deformation during the tensile test, which leads to inaccurate test results. Therefore, for the use of EVA (ethylene-vinyl acetate copolymer) or POE ( ethylene and butene; or high polymer of ethylene and octene) as the encapsulant film for double-glass photovoltaic modules, when the encapsulant film and ...
