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...
