Dual-glass photovoltaic module

Abstract

The invention relates to the technical field of a photovoltaic material, particularly to a dual-glass photovoltaic module. A packaging layer is arranged on the edges of a first glass layer and a second glass layer; an upper hot melting adhesive layer is arranged between the first glass layer and a first adhesive film layer; a lower hot melting adhesive layer is arranged between a second adhesive film layer and the second glass layer; one side, towards a battery piece, of the second glass layer is coated with a reflective coating layer, wherein the reflective coating layer is white organic polymer coating layer; and the reflective coating layer adopts a flat panel network-shaped. The dual-glass photovoltaic module disclosed by the invention is simple in structure and reasonable in design; and meanwhile, the structure of the dual-glass module is improved from the two aspects of increasing sunlight projection rate and preventing sunlight emission, so that the sunlight absorption performance of the dual-glass module is improved fundamentally, and the photovoltaic characteristic of the dual-glass module is improved.

Description

technical field [0001] The invention relates to the technical 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] In order to improve the insulation and water resistance performance of the double-glass photovoltaic module, a certain width of hot melt adhesive can be coated around the photovoltaic module, and the coating of hot melt adhesive requires special equipment to be heated, and it is easy to cause dirt during the coating process. Pollution and other problems, low process feasibility: At the same time, after the coating is completed, the hot melt adhesive will flow unevenly during the lamination process, resulting in uneven inner edges of the hot...

[0003] In order to improve the insulation and water resistance performance of the double-glass photovoltaic module, a certain width of hot melt adhesive can be coated around the photovoltaic module, and the coating of hot melt adhesive requires special equipment to be heated, and it is easy to cause dirt during the coating process. Contamination and other problems, low process feasibility: At the same time, after the coating is completed, the hot melt adhesive will flow unevenly during the lamination process, resulting in uneven inner edges of the hot melt adhesive and poor appearance, which will affect the appearance of the entire component
