Embodiment

[0040] Example: Preparation of the ultra-thin double-glass photovoltaic module of the present invention.

[0041](1) First, select a rectangular ultra-clear embossed tempered glass with a thickness of 2mm, a width of 990mm, and a length of 1660mm as the upper glass 1, and set the two short sides on the surface defined by the length and width of the upper glass 1 as Head 101 and afterbody 102, then a thickness is 0.6mm on the head 101 pad, and width is 50mm, and length is the head strip adhesive film 2 (POE adhesive film) of 990mm (as figure 1 shown), and then lay an upper layer of packaging film 3 (POE film) with a thickness of 0.6mm, and the upper layer of packaging film 3 covers the head strip film 2.

[0042] (2) First place an insulating backplane 4 (TPT backplane) with a thickness of 0.34mm, a width of 50mm, and a length of 150mm at the position corresponding to the center of the head 101 of the upper glass 1. The insulating backplane 4 is located at the Above the upper ...

Abstract

The invention belongs to the technical field of optoelectronic devices and relates to a preparation method of an ultra-thin double-glass photovoltaic module and a product thereof. Specifically, the method of the present invention comprises the following steps of (1) setting an upper layer glass and an upper layer packaging film and adding a head strip film between the upper layer glass and the upper layer packaging film, (2) setting an insulating back sheet, a battery string and a bus bar, (3) setting a lower layer packaging film and adding a tail block-shaped film, a tail strip-shaped film, ahead block-shaped film and a bus bar bending block-shaped film between the battery string and the lower layer packaging film, (4) setting lower layer glass and obtaining a laminated assembly, (5) laminating the laminate assembly, and (6) carrying out chamfering, installing a junction box and connecting a lead-out wire. According to the preparation method of the invention, the problems of air bubbles, delamination, lack of glue, and series and parallel extension in the production process of the ultra-thin double-glass photovoltaic module are solved, and the production efficiency and the yieldof the module are improved.

Description

technical field [0001] The invention belongs to the technical field of photoelectric devices, and relates to a preparation method of an ultra-thin double-glass photovoltaic module and a product thereof. Background technique [0002] With the development of technology, photovoltaic modules (also known as solar panels) have been widely used in solar power generation. The structure of traditional photovoltaic modules includes multiple sheets such as glass, adhesive film, battery sheet, adhesive film and back sheet. These sheets are bonded together by lamination under certain temperature, pressure and vacuum conditions, and then in the Put an aluminum frame around it, and install a junction box on the back panel, and finally get a photovoltaic module. The water vapor transmission rate of the backsheet of this type of module is high, which affects the quality of the adhesive film and the battery sheet, thereby reducing the power generation efficiency and life of the module. In ...
