Example Embodiment

[0024] Example one, such as figure 2 As shown, the surface of the transparent PET film 1 is marked with openings, and the positive electrode lead 8 and the negative electrode lead 9 are drawn from the opening on the surface of the transparent PET film 1 to the outside of the thin solar photovoltaic module.

Example Embodiment

[0025] Example two, such as image 3 As shown, the surface of the waterproof cloth 7 is marked with openings, and the positive electrode lead 8 and the negative electrode lead 9 are drawn from the opening on the surface of the waterproof cloth 7 to the outside of the thin solar photovoltaic module.

Example Embodiment

[0026] Example three, such as Figure 4 As shown, the positive electrode lead 8 and the negative electrode lead 9 are drawn from the side along the plane of the solar cell string 3 to the outside of the light and thin solar photovoltaic module.

[0027] The production method of thin and light solar photovoltaic modules has the following steps:

[0028] a. Laminate: Take a piece of ultra-white tempered glass and place it on the workbench. Lay transparent PET film 1, upper layer EVA2, welded solar cell string 3, middle layer EVA4, epoxy on the ultra-white tempered glass from bottom to top. Resin board 5, lower EVA6 and waterproof cloth 7, use transparent tape to fix the uppermost layer of waterproof cloth 7 on the ultra-white tempered glass, and finally lay high temperature cloth on the waterproof cloth 7;

[0029] b. Laminating: Put the laminated photovoltaic modules into a laminator for laminating. After the lamination is completed, remove the ultra-white tempered glass and high tem...

Abstract

The invention provides a light and thin type solar photovoltaic component and a producing method thereof. The light and thin type solar photovoltaic component comprises a transparent polyethylene terephthalate (PET) thin film, an upper layer ethylene vinyl acetate (EVA), a solar battery string, a middle layer EVA, an epoxy resin plate, a lower layer EVA and a waterproof cloth which are sequentially stacked, a layer of waterproof cloth is pressed on the rear side of the epoxy resin plate of an existing PET solar photovoltaic component, the contact of the EVA and the air can be reduced, and the aging of the EVA can be relieved. Battery slices and the epoxy resin plate are clamped in the middle by the transparent PET thin film on the top layer and the waterproof cloth on the bottom layer, the delaminating probability of the transparent PET thin film from the epoxy resin plate is greatly reduced, and simultaneously the attractiveness of a whole product can be improved by various appearances of the waterproof cloth.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a light and thin solar photovoltaic module and a production method thereof. Background technique [0002] With the use of solar power generation technology in small applications, such as solar outdoor chargers, solar cell modules with light weight, good appearance and thin body have become a new demand. The Chinese patent application number is 200610038976.3, and the publication date is August 30, 2006. A method of encapsulating solar modules by glue-dropping has been announced. Light, but the disadvantage is that due to the fluidity of the glue, it is difficult to make the glue evenly cover the solar panel when making solar panels above 5W, and if excessive glue is added to allow the glue to fully cover, then It is easy to form overflow glue around the substrate when heating, and it is difficult to remove the overflow glue after cooling, resulting in poor appearance...
