Abstract

The invention provides a solar cell back panel base material, a method for preparing the same and a solar cell back panel. The solar cell back panel base material comprises a core material layer. Thecore material layer comprises, by weight, 60-85 parts of polyolefin, 1-30 parts of heat-resistant reinforcing resin, 1-5 parts of toughening agents, 1-5 parts of compatibilizers, 0-20 parts of inorganic fillers and 0-3 parts of auxiliaries. The solar cell back panel base material, the method and the solar cell back panel have the advantages that the method is simple, the solar cell back panel basematerial prepared by the aid of the method is good in water vapor barrier ability and excellent in heat stability and mechanical property and can be widely used for processing solar cell piece back panels; the solar cell back panel is easy to form and good in water vapor barrier property, can be recycled and is excellent in packaging film adhesion, cell pieces can be prevented from being oxidized, the power generation efficiency of the cell pieces can be improved, and the service lives of solar cell assemblies can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of solar battery backplanes, and relates to a solar battery backplane base material, a preparation method and a solar battery backplane. Background technique [0002] In the field of solar power generation, the backsheet of the solar module is located on the outermost layer on the back of the module, which protects and supports the cells. The backsheet should have reliable electrical insulation, water vapor barrier and good aging resistance. In order to keep solar cells in the best working condition and maintain a 25-year service life, the backsheet should have excellent water vapor barrier and hydrolysis resistance, which is one of the important indicators to measure the performance of the backsheet. If the water vapor barrier of the solar backsheet is poor, water vapor will penetrate into the packaging system through the backsheet, which will affect the adhesion of the packaging film, cause delamination b...
