Embodiment

[0019] Example: such as figure 1 Shown, a kind of lamination process of novel solar energy flexible component, described process method comprises: S1: prepare required material: solar TPT back plate, solar cell sheet, EVA adhesive film (ethylene-vinyl acetate copolymer), ETFE ( Ethylene-tetrafluoroethylene copolymer);

[0020] S2: Lamination, from the bottom to the top, the solar TPT backplane, EVA film, solar cell, and EVA film are laminated sequentially;

[0021] In this embodiment, the solar TPT backplane has a thickness of 2-3 mm, the EVA adhesive film has a thickness of 0.3-0.8 mm, and the solar cell is a crystalline silicon cell.

[0022] S3: EL test before lamination, through the EL detector to detect whether the solar module is damaged during the lamination process;

[0023] S4: Lamination, put the solar modules that have passed the EL test on the loading table of the laminator, and package the components in an environment of 142 degrees Celsius. It should be noted t...

Abstract

The invention relates to a novel solar flexible module film laminating process. The key points of the technical scheme are as follows: S1, required materials are prepared, including a solar TPT backplane, a solar cell, EVA adhesive films and ETFE; S2, stacking is carried out: the solar TPT backplane, one EVA adhesive film, the solar cell and the other EVA adhesive film are stacked in turn from bottom to top; S3, El test is carried out before laminating; S4, laminating is carried out: a solar module is packaged at 142 DEG C; S5, ETFE melting is carried out: ETFE is put into heating equipment, and ETFE is heated to 275 DEG C to melt into liquid; S6, coating is carried out: the melted liquid ETFE is conveyed to the working head of coating equipment through a hydraulic or liquid electric pumpdevice, and the working head enters a set working starting point to start coating after the solar module enters the coating equipment; S7, El test is carried out after the coating is cooled; S8, lasercutting is carried out; and S9, the preparation of the module is completed. Abnormalities such as wrinkles and displacement caused by the ETFE film are avoided, and the life of solar modules is increased.

Description

technical field [0001] The invention relates to the technical field of solar component manufacturing, in particular to a film coating process of a novel solar flexible component. Background technique [0002] With the development of social economy and the improvement of people's living standards, people's desire to use clean energy to replace fossil energy is becoming stronger and stronger. Solar energy, as the most widely used new energy, has attracted more and more attention. Popularity, solar cell modules have played an increasingly important role in people's lives. [0003] The flexible solar photovoltaic modules that have been disclosed are all made of 0.05mm thick ETFE film or transparent 0.3mm TPT lamination. Because the weather resistance of transparent TPT film is worse than that of ETFE film, and ETFE film is very thin and cannot be laminated. During the process, it is easy to produce wrinkles, displacement and poor adhesion with EVA. [0004] Therefore, it is ne...
