Embodiment 1

[0035] Such as figure 2 As shown, this embodiment provides a glass photovoltaic building material component, which is composed of a fluoroplastic film 5, a resin-based composite film 1, an ethylene-vinyl acetate copolymer layer 3, a solar cell string 4, a resin-based composite film 2, and glass 6. Laminating machine hot pressing.

[0036] The above-mentioned two-layer resin-based composite film is composed of fiber material and powder coating. The fiber material is made by weaving one or any combination of glass fiber, carbon fiber or aramid fiber, and the single filament diameter of the fiber material ranges from 3 to 23 μm. The fiber material is woven into fiber cloth, and the weight per unit area of ​​the fiber cloth is between 30 and 400 grams per square meter. The powder coating is selected from polyester powder coating, epoxy powder coating, acrylic powder coating, polyurethane powder coating and fluorocarbon powder coating.

[0037] The glass 6 is selected from one ...

Embodiment 2

[0044] This embodiment provides another glass photovoltaic building material component, which consists of a fluoroplastic film, a resin-based composite film, a first layer of ethylene-vinyl acetate copolymer layer, a solar cell string, a second layer of ethylene-vinyl acetate copolymer layer, glass It is heat-pressed by a laminator.

[0045] Compared with Embodiment 1, this embodiment differs in that the resin-based composite film material can be replaced by an ethylene-vinyl acetate copolymer layer. That is, the glass photovoltaic building material component in Example 1 has two layers of resin-based composite film and one layer of ethylene-vinyl acetate copolymer layer, while the glass photovoltaic building material component in this embodiment has one layer of resin-based composite film and two layers of ethylene-vinyl acetate copolymer. Vinyl acetate copolymer layer.

[0046]The resin-based composite film is composed of fiber material and powder coating. The fiber materi...

Embodiment 3

[0054] This embodiment provides another glass photovoltaic building material component, which consists of a fluoroplastic film, a first resin-based composite film, a first layer of ethylene-vinyl acetate copolymer, a solar cell string, and a second layer of ethylene-vinyl acetate copolymer 1. The second resin-based composite film and the glass are formed by hot pressing with a laminator.

[0055] Compared with Example 1 and Example 2, this example differs in that the glass photovoltaic building material component in this example has two layers of resin-based composite films and two layers of ethylene-vinyl acetate copolymer. While the glass photovoltaic building material member in Example 1 has two layers of resin-based composite films and one deck of ethylene-vinyl acetate copolymer layers, the glass photovoltaic building material member in Example 2 has one deck of resin-based composite films and two layers of ethylene-vinyl acetate copolymer layers. Copolymer layer.

Abstract

The invention discloses a glass photovoltaic building material component and a preparation method thereof. The glass photovoltaic building material component is formed by carrying out hot pressing ona fluorine plastic film, a first resin-based composite film material, a first EVA, a solar battery string, a second resin-based composite film material, and a piece of glass by a lamination machine. The component having characteristics of high power generation efficiency, high long-term reliability, long service life, and good safety performance not only has good glass-curtain-wall thermal insulation, sound insulation, ultraviolet-proof, and fragmented falling prevention performances but also can realize the high solar energy conversion efficiency of crystalline silicon and high-stability lighting and power generation performances. Meanwhile, the beautiful arc and the single large-dimension component are realized during the manufacturing process. The glass photovoltaic building material component is especially suitable for the complex-hook-surface-included building like a curved wall, a lighting roof, an agricultural greenhouse, a sun room, a parking shed, and a waiting hall.

Description

technical field [0001] The invention relates to a component, in particular to a glass photovoltaic building material component and a preparation method thereof, belonging to the field of photovoltaic technology. Background technique [0002] In the current society, energy conflicts and environmental problems are becoming more and more prominent, and the development of various types of clean energy is an inevitable trend. In recent years, the photovoltaic industry has developed rapidly, and technological updates have been gradually accelerated. At present, the photovoltaic industry is developing towards product diversification, and building photovoltaics is one of the most important markets in the field of photovoltaic power generation applications in the world. [0003] Ordinary crystalline silicon solar modules or thin-film solar modules often use opaque backsheet materials and low structural safety, so they cannot be directly used as building components. They can only be c...
