High-power high-reliability solar module

Abstract

The invention relates to a high-power high-reliability solar module, in particular to a solar module which is light, thin, high in efficiency and long in service life. The high-power high-reliability solar module solves the ageing problem of a traditional back plate structure and solves the problem that figured glass is too thin or too thick and causes low efficacy of solar modules. The high-power high-reliability solar module comprises a lower layer of tempered glass, a lower adhesion layer, a solar cell, an upper adhesion layer, a glass sphere layer and an upper layer of tempered glass, or the high-power high-reliability solar module comprises the lower layer of tempered glass, the lower adhesion layer, the solar cell, the upper adhesion layer and the upper layer of tempered glass, wherein the upper adhesion layer or the lower adhesion layer or the two adhesion layers are mixed with refraction particles. The efficiency of the high-power high-reliability solar module can be effectively improved.

Description

technical field [0001] This application relates to a high-power and high-reliability solar module, especially a light, thin, high-efficiency and long-life solar module. Background technique [0002] Solar energy is currently the most popular environmentally friendly energy source. In general, the photovoltaic effect of a solar cell converts solar energy into electricity. [0003] The solar cell module is usually a multi-layer structure composed of patterned glass / adhesive layer / photoelectric component / adhesive layer / solar back sheet with a thickness of about 3.2 mm, plus aluminum, galvanized steel, wood or synthetic materials (such as polyester) ethylene, polypropylene, ethylene propylene rubber, etc.), a junction box, wires, batteries and other peripheral components. [0004] The glass used in the solar cell module needs to be tempered to increase strength and durability, and the glass embossing can make the incident sunlight produce light scattering, which is used to inc...

AI Technical Summary

Problems solved by technology

[0005] However, the traditional backplane structure has aging problems, which makes it difficult for the solar module to meet the basic requirement of a service life of 20 years; if the original traditional backplane structure is replaced by embossed glass with a thickness of about 3.2 mm, it may cause solar modules. Too thick; however, if only 2 mm toughened glass is used, the glass thickness is too thin, and there is no embossing technology for such thin glass, which will cause the efficiency of the solar module to be low
