The current methods to improve the above problems are mainly by changing the color of the front plate, changing the color of the adhesive film, or scribing the photovoltaic chip with laser. However, the change of the color of the front plate and the adhesive film can sacrifice part of light transmittance in different degrees, and the power generation efficiency is influenced; and the power generation amount is lost by scribing the photovoltaic chip by using the laser.

Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.
Example one
Fig. 1 shows a flow chart of a 3-layer front panel manufacturing method according to an embodiment of the present application.
The following will describe and explain in detail the method for manufacturing the 3-layer front sheet provided in the present application by way of specific examples.
As shown in fig. 1, the 3-layer front plate is prepared as follows:
and S101, providing a base material layer of the front plate of the thin-film solar module.
The substrate layer of the front plate of the thin-film solar module is a flexible polymer film, and the flexible polymer film comprises at least one of the following components: transparent fluorine-based resin, polyethylene terephthalate, polyethylene naphthalate, polycarbonate, and polymethyl methacrylate.
The fluorine-based resin includes at least one of: polychlorotrifluoroethylene, an ethylene-tetrafluoroethylene copolymer, an ethylene-chlorotrifluoroethylene copolymer, a chlorotrifluoroethylene-tetrafluoroethylene copolymer, a tetrafluoroethylene-hexafluoropropylene copolymer, a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, polyvinylidene fluoride, a tetrafluoroethylene-hexafluoropropylene ethylene copolymer.
In this example, a transparent ethylene-tetrafluoroethylene copolymer (ETFE) fluororesin having good weather resistance was selected as the base material layer of the front sheet of the thin film solar module. The thickness of the ETFE membrane material is usually less than 0.20mm, and the ETFE membrane material is an excellent transparent membrane material. ETFE has the following advantages: the flame retardant is extremely suitable for water, fuel, oil and acid-base environments and has high flame retardance; and the mechanical property is better: the high-strength high-toughness high-strength high. ETFE is also a good dielectric material: high dielectric strength, high resistivity, low dissipation factor (typically dissipation factor of only 0.003), low dielectric constant and substantially constant over variations in frequency and temperature.
Step S102, providing an adhesive layer of a front plate of the thin film solar module.
The bonding layer of the front plate of the thin film solar module comprises at least one of the following components: polyvinyl butyral, polyurethane, thermoplastic polyolefin, ethylene-vinyl acetate copolymer, high polymer of ethylene-butylene, and organosilicon.
In this embodiment, since the substrate layer of the front plate of the thin-film solar module is a polymer film, a high polymer of ethylene-butene (POE) with a low softening point is selected as the bonding layer of the front plate of the thin-film solar module. POE has light weight, high transparency, good toughness, good flexibility and other excellent performances.
Step S103, providing a color three-dimensional pattern layer of the front plate of the thin film solar module.
The color three-dimensional pattern layer of the front plate of the thin-film solar module is a polymer film processed by a laser process, and comprises at least one of the following components: a biaxial stretching polypropylene laser film, a polyvinyl chloride laser film and a polyethylene terephthalate laser film.
The colorful three-dimensional pattern layer arranged in the front plate of the thin-film solar module adopts an easily purchased and cheaper laser film, the laser film is colorful and has patterns which can be designed, and better three-dimensional effects can be presented at different angles. In order to ensure good light transmittance, the color three-dimensional pattern layer in this embodiment is made of a polyethylene terephthalate laser film (PET-based laser transparent film). The PET-based laser transparent film is a polymer film processed by a laser process, the laser process is to utilize a laser light source to record light wave amplitude information and corresponding information simultaneously in a very short time, each mass point forming an image is reflected by utilizing the interference principle of light to manufacture a colored three-dimensional pattern, the specific technology is to adopt design technologies such as a computer dot matrix photoetching technology, a 3D color holographic technology, a multiple and dynamic imaging technology and the like, the designed pattern is gorgeous, three-dimensional patterns with different colors are presented at different observation angles, and the pattern can be designed according to own favor. It should be noted that, in addition to the laser transparent film, the laser film may also be a laser dielectric film, a laser aluminum-plated film, a laser aluminum-washed film, a laser rainbow film, or a laser transfer film. Above-mentioned when setting up the polymer laser film that will have colored stereoeffect in the front bezel, whole decorative effect is good to can keep the good light transmissivity of front bezel. Meanwhile, the production process of the polymer laser film is relatively mature, the cost of the polymer laser film is low, and the polymer laser film has a wide application prospect in photovoltaic modules.
And S104, sequentially placing the base material layer of the front plate of the thin-film solar module, the bonding layer of the front plate of the thin-film solar module and the colorful three-dimensional pattern layer of the front plate of the thin-film solar module to form a laminated structure and bonding.
