Problems solved by technology

However, this kind of adhesive is simply added and physically mixed, and the polyolefin film is bonded to glass, battery sheet, back sheet, etc. only by Van der Waals force, so that the polyolefin film and glass, polyolefin film The peel strength between the battery sheet, polyolefin film and the back sheet is relatively small, and this kind of solar cell module is easy to cause delamination in daily light use, resulting in module failure
In addition, the polyolefin resin used in the non-crosslinked polyolefin film has a melting point between 70 and 90°C. During daily use of solar cell modules, due to sunlight, the surface temperature of the components can easily reach about 80°C. The polyolefin film will soften and deform, causing defects such as cell displacement and internal bubbles

Abstract

The invention discloses an anti-PID (potential induced degradation) polyolefin adhesive film for a solar cell module. The anti-PID adhesive film is an A / B / A three-layer film; the mass ratio of three layers A, B and A is (10-20):(60-80):(10-20); the layer B of adhesive film is a copolymer of ethylene and alpha-olefin; the DSC (differential scanning calorimetry) melting point of the layer B of adhesive film is higher than 90 DEG C. The anti-PID polyolefin adhesive film has the advantages that the permeation rate of water vapor is lower, the volume resistivity is higher, and the solar cell module has better anti-PID property; by matching with the outer layer A of the adhesive film, the crosslinking property, adhering property and flexibility of low-melting point polyolefin resin composition, and the heat-resistant property, blocking property and electric insulation property of high-melting point polyolefin resin composition are also realized.

Description

technical field [0001] The invention relates to an anti-PID polyolefin adhesive film used for solar battery modules. Background technique [0002] Solar cell modules are devices that use the photoelectric effect of materials to directly convert the light energy of sunlight into electrical energy. Solar energy is a rich renewable energy source. In today's society, environmental problems and energy conflicts are becoming more and more serious. The development of sustainable clean Energy is an inevitable trend. Countries and governments around the world have adopted a series of measures to support the photovoltaic industry in order to ensure energy supply and reduce environmental pollution. Solar power generation has become a new type of energy supply method and has been extensively and rapidly developed. [0003] The existing conventional solar cell packaging structure is as follows: the upper layer is tempered glass, the middle layer is the cell, the lower layer is the back s...
