Abstract

The invention discloses a preparation method of a photovoltaic prefabricated member. The preparation method comprises the following steps: laying a glue film on glass; then laminating the adhesive film and the glass to bond the adhesive film and the glass into a whole, and pre-crosslinking the adhesive film; and then embedding the strip-shaped conductive connecting piece into the adhesive film. According to the method, the existing layout and laying sequence of photovoltaic module raw materials is broken through, and the glass, the adhesive film and the strip-shaped conductive connecting piece are prepared into an integral prefabricated part in advance; the three steps in the manufacturing process of the photovoltaic module are separated from the production line, the manufacturing speed of the production line can be increased, and the yield is increased.

Description

technical field [0001] The invention relates to the field of photovoltaics, in particular to a preparation method of a photovoltaic preform. Background technique [0002] The current mainstream photovoltaic module structure includes sequentially stacked: glass, high-transparency EVA or POE film, cell, high-resistance film, and backplane. And it is necessary to laminate the glass, high-permeability EVA or POE film, battery sheet, high-resistance film, and backplane in sequence. The lamination and lamination efficiency of existing photovoltaic modules needs to be improved. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a preparation method of a photovoltaic preform, the photovoltaic preform includes glass, an adhesive film, and a strip-shaped conductive connector stacked in sequence; the preparation method includes the following steps: laying the adhesive film on the glass ; Then the adhesive film and the glass are laminated, so that th...
