High-temperature cloth, photovoltaic module and preparation method thereof

Abstract

The invention discloses high-temperature cloth, a photovoltaic module and a preparation method of the photovoltaic module, which relate to the technical field of photovoltaic power generation. The surface of the photovoltaic module is provided with concave textures; and the concave textures are linear. Convex textures are arranged on the surface of the high-temperature cloth; and the convex textures are matched with the concave textures of the photovoltaic module in shape. The photovoltaic module disclosed by the invention has the beneficial effects that the concave texture on the surface of the photovoltaic module is linear, and the linear concave texture enables the thickness of the adhesive film between the upper surface layer and the internal structure layer of the photovoltaic moduleto be relatively uniform, so that the adhesive force is relatively uniform, and the problem of delaminating of an area with weak adhesive force caused by aging of the adhesive film is avoided.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a high-temperature cloth, a photovoltaic module and a preparation method thereof. Background technique [0002] In the prior art, the upper surface layer of photovoltaic modules such as charging paper is generally provided with a concave-convex texture. [0003] The concave-convex texture in the prior art is generally in the shape of pits formed by a plurality of circular depressions. [0004] The contriver finds in the process of implementing the present invention, because the adhesive film at the peak and valley place of circular depression is extremely thin, so at this position, the bonding strength of surface material and internal structure layer is low, when to this kind of pitted texture After the aging test or long-term exposure of photovoltaic modules, the surface material and the internal structure layer are prone to delamination at the peaks and v...
