Problems solved by technology

The use of tempered glass can meet the strength requirements of the building structure, but the anti-radiation effect of ultra-clear tempered glass is relatively poor, and unblocked sunlight will cause certain harm to people living indoors, and only two layers of glass are used as roofs or walls The insulation effect of buildings is very limited, especially in the north, where the indoor heat is dissipated too quickly in winter, resulting in a drop in indoor temperature, making it difficult for people to live, resulting in a large number of vacant houses

Embodiment Construction

[0015] like figure 1 The heat-preservation type solar cell assembly provided with a multi-layer protective film includes a cover glass 1 and a back glass 3 for fixing solar cells 2, and a heat-insulating glass 4 is arranged parallel to the bottom of the back glass 3, and the heat-insulation The glass 4 and the edge of the back glass 3 are fixed and sealed with a structural glue 5 to form a cavity 6; the cavity 6 is evacuated to enhance the thermal insulation effect of the solar cell module when used as a building structure. Wherein, the two sides of the insulating glass 4 are respectively coated with protective films 41 and 42 .

[0016] still as figure 1 As shown, the protective film 41 is a nano-metal film coated on the surface of the hollow layer of the insulating glass 4, and the nano-metal film is coated with 6 layers. Ensure that the transmittance of visible light is not less than 75%, while completely blocking ultraviolet rays and other radiation from entering the hou...

Abstract

The invention discloses a thermal insulation type solar battery pack provided with multiple layers of protective films. The solar battery pack comprises back plate glass used for fixing a solar battery plate, wherein thermal insulation glass is arranged below the back plate glass in parallel and fixedly sealed with the edge of the back plate glass via structural adhesive, and a hollow cavity is formed among the thermal insulation glass, the back plate glass and the structural adhesive. The protective films are respectively plated at two sides of the thermal insulation glass. According to the thermal insulation type solar battery pack, the thermal insulation effect of the solar battery pack used as the building structure is greatly enhanced; radiations such as ultraviolet rays are fully isolated from the house while the transmittance of visible lights is not less than 75%, thereby ensuring that people in the house cannot be sunburnt by ultraviolet rays and the like; and the heat loss speed of the house in winter is slowed down so that the house is suitable for people to live in cold winter.

Description

technical field [0001] The invention relates to a photovoltaic module, in particular to a thermal insulation solar cell module provided with a multi-layer protective film. Background technique [0002] With the acceleration of the pace of my country's industrialization process, the problem of energy in short supply has gradually emerged, which is mainly manifested in electricity. In recent years, in response to the problem of insufficient electric energy, the state has vigorously supported the technical research and popularization and application of renewable energy. Double-glass solar cell modules have been widely used as roofs, walls and windows of houses. The double-glass solar cell module is to use two layers of glass to sandwich several groups of solar cells in the middle, and each group of cells leads to the junction box. The white tempered glass has good light transmission performance and increases the conversion rate of the solar panel. The use of tempered glass ca...
