Double-glass photovoltaic module

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...
