Embodiment 1

[0016] The present invention discloses a double-glass photovoltaic module, which includes a first glass layer 1 , a first adhesive film layer 2 , a battery sheet 3 , a second adhesive film layer 4 and a second glass layer 5 from top to bottom.

[0017] The upper surface of the first glass layer 1 is uniformly coated with TiO with a thickness of 50-150 nm 2 -SiO 2 The high anti-reflection nano film has a transmittance of more than 98.5% to sunlight, which effectively improves the transmittance of solar energy on the glass, thereby providing the necessary prerequisites for the solar cells to absorb sunlight.

[0018] The first adhesive film layer 2 is a transparent and highly transparent EVA adhesive film, which has full transparency to sunlight. The second adhesive film layer 4 is common EVA adhesive film or PVB adhesive film.

[0019] Both ends of the first adhesive film layer 2 and the second adhesive film layer 4 are sealed and connected; the battery sheets 3 are horizonta...

Abstract

The invention discloses a double-glass photovoltaic module, which sequentially comprises a first glass layer, a first adhesive film layer, battery pieces, a second adhesive film layer and a second glass layer from top to bottom, wherein the upper surface of the first glass layer is evenly coated with a high anti-reflection nano membrane; the first adhesive film layer is a transparent high-transmittance EVA adhesive film; two ends of the first adhesive film layer and the second adhesive film layer are tightly connected with each other; the battery pieces are horizontally arranged in a seal cavity comprising the first adhesive film layer and the second adhesive film layer; and an anti-projection film is laid at two ends of the seal cavity and on the upper surface of the second adhesive film. The double-glass photovoltaic module is simple in structure and reasonable in design; the structure of the double-glass module is improved from two aspects of increasing the projection ratio of sunlight and blocking emitting of the sunlight; the absorption capability of the double-glass module on the sunlight is fundamentally improved; and the photovoltaic properties of the double-glass module are improved.

Description

technical field [0001] The invention relates to the field of photovoltaic materials, in particular to a double-glass photovoltaic module. Background technique [0002] With the continuous development of photovoltaic technology, photovoltaic modules have been widely used in many industries such as construction engineering. Double-glass photovoltaic modules are a relatively common photovoltaic module. people's attention. [0003] Photovoltaic double-glass modules are devices that use panels to absorb solar energy and store electricity. Therefore, how to improve the absorption rate of solar energy by panels becomes the key to improving the photovoltaic performance of double-glass photovoltaic modules. The prior art mainly uses white film or low-reflectivity film as the film on the back plate of the battery panel, so that the solar energy directed to the double-glass module can be reused to improve the utilization rate of solar energy and the light storage performance of the ph...
