preparation example Construction

[0044] The present invention also provides a method for preparing the above-described photovoltaic film, see figure 2 , Including the following steps:

[0045] Step S210: Dissolving the Easy Sub-Material Material in the preset dispersant, forming a slurry, the sublimation temperature of the elastnics material is less than the maximum temperature of the lamination;

[0046] Specifically, the Yi Limited material is one or more of the nap, trichloride or anthracene, by providing a surface of the cell sheet 5 of naphthalene, aluminum chloride and the silica material, conductive silver paste (Al, Ag), The material such as a tin copper strap (Sn, Pb) is difficult to react, and after lamination of laminated flow, naphthalene or trichloride, it can effectively avoid the effect of residual substance to effectively affect the performance of the photovoltaic assembly. Correspondingly, the preset dispersant comprises a N-methylpyrrolidone solvent (NMP solvent) of polyvinylidene fluoride (PVDF)...

Embodiment 1

[0056] (1) Preparation of anti-skid slurry:

[0057] 10 g naphthalene (naphthalene 25 ° C at room temperature, the sublimation phenomenon) N-methylpyrrolidone solvent (NMP solvent), thoroughly stirred, mixed, mixed uniform, forming a slurry;

[0058] (2) Preparation of anti-skid pattern photovoltaic film:

[0059] The pulp film is attached to the hollow film in the preset shape, and the slurry is added at the hollow film of the hollow film. After the slurry is cured, the hollow film is removed. A non-slip structure 2 is formed on the film body 1, wherein the preset shape is a wave shape.

Embodiment 2

[0061] (1) Preparation of anti-skid slurry:

[0062] 10 g of trichloride (sublimation temperature 178 ° C) was dissolved in 20 ml of polyvinylidene fluoride (PVDF) N-methylpyrrolidone solvent (NMP solvent), thoroughly stirred, mixed uniform, mixed, forming a slurry;

[0063] (2) Preparation of anti-skid pattern photovoltaic film:

[0064] In the film body 1 (PoE), it is attached to the hollow film in the preset shape, in which the hollow position is disposed at intervals of adjacent two semiconductor sheets, and the pulp is added to the hollow film. When the slurry is cured, the hollow film is removed to form a non-slip structure 2 on the glue film body 1, wherein the preset shape is a wave shape.

Abstract

The invention provides a photovoltaic module, a photovoltaic adhesive film and a preparation method thereof. The photovoltaic adhesive film includes an adhesive film body and an anti-skid structure, the adhesive film body has a first surface, and the anti-skid structure is provided on the first surface. The sublimation temperature of the non-slip structure is less than the maximum temperature during lamination.

Description

Technical field [0001] Embodiments of the present invention relates to photovoltaic technologies, and particularly, to a photovoltaic module, the photovoltaic film and its preparation method. Background technique [0002] With the green concept is growing in popularity, the photovoltaic industry is flourishing. PV modules mainly by the panel, a first film, solar cells, a second film, and the back plate and other components. Wherein the first adhesive material is an adhesive film between the cell sheet and the panel, a second film adhesive material between the battery plate and the back plate. [0003] A first prior art film, a second non-adhesive film, capable of crosslinking at a cure temperature at room temperature, using the method of extrusion can be effective to form a stable, reliable film layer, connected to the battery and functions function of the glass and backsheet. [0004] However, during the preparation of the photovoltaic module, the first film and the second film ...
