Problems solved by technology

In the prior art, the flexible solar cell packaging board mainly adopts a composite film, including ETFE film, UV barrier film, water blocking film, PET film, etc. However, the existing front plate has a single color and cannot meet the diversification of solar cells. Product demand; moreover, the existing products have poor water vapor barrier effect, are not resistant to aging, have a short service life, complex and time-consuming packaging process, and it is difficult to further improve the light transmission effect, which affects the reliability of solar cells

Abstract

The invention provides a solar cell packaging plate and a preparation method thereof, and a solar cell; the solar cell packaging plate with rich colors can be prepared through a first coating layer, and therefore the requirements of diversified products of the solar cell can be met; a fluorine film layer is bonded through a second coating layer, so that the light transmittance and the anti-aging effect of the solar cell packaging plate are improved, and meanwhile, the solar cell packaging plate is more resistant to abrasion and scratch, and has a self-cleaning function; the adhesion force of ablocking layer can be improved by arranging a third coating layer; due to the arrangement of the blocking layer, the solar cell packaging plate has relatively high water resistance; the light transmittance and the ageing resistance of the solar cell packaging plate can be further improved by arranging a packaging layer, and the solar cell packaging plate can resist aging for more than 25 years, can be stored and laminated more easily, and is safe and environment-friendly; and meanwhile, a simple packaging process, product integration, convenience in use, a time-saving and efficient subsequentpackaging process and relatively low cost are achieved.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar cell packaging plate, a preparation method thereof, and a solar cell. Background technique [0002] As a new type of solar cell, flexible thin-film solar cell has been paid more and more attention by people because of its advanced technology, excellent performance and wide application. Due to the special application environment of flexible thin-film solar modules, solar cell packaging panels are required to have certain light transmission, aging resistance, insulation, self-cleaning, flame retardancy, windability and color properties. In the prior art, the flexible solar cell packaging board mainly uses a composite film, including ETFE film, UV barrier film, water blocking film, PET film, etc. However, the existing front plate has a single color and cannot meet the diversification of solar cells. Product demand; and the existing products have poor water vapor barrie...
