Abstract

The invention belongs to the technical field of photovoltaic materials, and particularly relates to a photovoltaic module panel, a preparation method thereof and a photovoltaic module. The preparationmethod of the panel comprises the steps of carrying out activating treatment on a base material; coating one surface of the activated base material with a fluorine coating on, and coating the other surface of the activated base material with a polyester coating; and depositing a barrier layer on the surface of the polyester coating by adopting a film coating process. The photovoltaic module panelprovided by the invention does not comprise a bonding layer, so that the number of layers is reduced, the cost is reduced, the problems that the bonding force between functional layers is poor and the use requirements cannot be met are solved, and the heat dissipation capability of the module is improved at the same time.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic materials, and in particular relates to a photovoltaic module plate, a preparation method thereof and a photovoltaic module. Background technique [0002] Flexible solar cells are a type of thin-film solar cells, which usually include three parts, namely, the front plate of the battery, the core component of the battery, and the back plate of the battery. Flexible solar cells have the advantages of light weight, foldable, curly, and easy to carry, and can even be pasted on the surface of other objects (such as car glass, clothes, etc.), integrated on windows or roofs, external or internal walls, etc., for The field of mobile energy provides infinite possibilities, so it has been paid more and more attention by people. [0003] Thin-film solar cells, including: amorphous silicon, microcrystalline silicon, copper indium gallium selenide, cadmium telluride, dye-sensitized and organic types. No...
