Abstract
The utility model discloses a multiple-reflection high-efficiency solar photovoltaic assembly which comprises an assembly lamination layer. An aluminum alloy frame is installed on the periphery of the assembly lamination layer. The assembly lamination layer structurally comprises front plate glass, a first ethylene vinyl-acetate copolymer (EVA) packaging layer, a crystalline silicon battery, a second EVA packaging layer and a rear plate glass layer from top to bottom, wherein an antireflective film layer is coated on the upper surface of the front plate glass. The rear plate glass layer comprises a rear plate glass matrix, a mercury coating is arranged on the back of the rear plate glass matrix, and a primer coating is arranged on the back of the mercury coating. Due to the fact that light-facing surface glass is provided with the antireflective film layer, incident light can be increased, and accordingly generating power of the assembly is improved. Light projected to the surface of back plate glass undergoes diffuse reflection and is projected to a solar battery piece, secondary utilization of reflected light through the battery piece is reinforced, and generating power of the assembly is improved.
Description
Technical field
The utility model relates to a kind of multipath reflection high-efficiency solar photovoltaic module, is the architecture advances to current conventional Crystalline Silicon PV Module, belongs to the photovoltaic technology field.
Background technology
Photovoltaic module is the core of photovoltaic generating system.No matter the photovoltaic module of suitability for industrialized production is conventional crystal silicon cell photovoltaic module or thin-film cell photovoltaic assembly both at home and abroad at present, the back-panel glass adopted or backboard are all without bulge-structure or matte, 2 secondary reflections of light have so just been reduced, also just mean and reduced the 2 secondary response amounts of cell piece for light, reduced the generated output of assembly.In addition no matter be conventional crystal silicon cell photovoltaic module or thin-film cell photovoltaic assembly, back-panel glass (to the assembly exterior face) is the function of areflexia sunray all, before and after making, adjacent component can not repeatedly receive sunray, has reduced the light amount of incident, has reduced the generated output of assembly.
The utility model content
The utility model purpose is to provide a kind of have multipath reflection, high efficiency multipath reflection high-efficiency solar photovoltaic module.
Technical solution of the present utility model is:
A kind of multipath reflection high-efficiency solar photovoltaic module, comprise the assembly lamination, assembly lamination periphery is equipped with aluminum alloy frame, and it is characterized in that: component stack is followed successively by from top to bottom: upper surface is coated with front glass sheet, an EVA encapsulated layer, crystal silicon cell, the 2nd EVA encapsulated layer, the rear glass sheet layer of antireflection film layer; Wherein, the glass sheet layer comprises rear glass sheet matrix, and the rear glass sheet matrix back side arranges mercury coating, and the mercury coating back side arranges primer coating.
The primer coating of described rear glass sheet has bulge-structure or matte.
The phototropic face glass of this multipath reflection high-efficiency solar photovoltaic module, because antireflection film layer is arranged, can increase incident ray, and be conducive to cell piece and receive more light, thus the generated output of raising assembly; The rear glass sheet of this assembly scribbles primer coating and mercury coating in addition, wherein primer coating has bulge-structure or matte, for the light generation diffuse reflection that projects the back-panel glass surface, project on solar cell piece, strengthen the secondary utilization of cell piece to reflection ray, improve the generated output of assembly; In addition, rear glass sheet forms mirror after the processing through primer coating+mercury coating.When this assembly is arranged in system, except considering that mounting means, angle, regional shade etc. affect assembly and arrange the factor of distance, also to consider the existence of assembly back side mirror, when spacing is suitable between the two, the light reflection that can form, thereby increase the inlet of assembly incident ray, improved the generated output of assembly.
The phototropic face glass of the utility model solar photovoltaic assembly, because antireflection film layer is arranged, can increase incident ray, and be conducive to cell piece and receive more light, thus the generated output of raising assembly; The rear glass sheet of this assembly scribbles primer coating and mercury coating in addition, wherein primer coating has bulge-structure or matte, for the light generation diffuse reflection that projects the back-panel glass surface, project on solar cell piece, strengthen the secondary utilization of cell piece to reflection ray, improve the generated output of assembly; In addition, rear glass sheet forms mirror after the processing through primer coating+mercury coating.When this assembly is arranged in system, except considering that mounting means, angle, regional shade etc. affect assembly and arrange the factor of distance, also to consider the existence of assembly back side mirror, when spacing is suitable between the two, the light reflection that can form, thereby increase the inlet of assembly incident ray, improved the generated output of assembly.
The utility model assembly is when work, sunlight is entering component internal through antireflection layer, the bulge-structure of back-panel glass or matte, make the reflection ray on back-panel glass surface form diffuse reflection, finally make reflection ray project uniformly on solar cell, increase the amount of incident of solar battery surface sunray, thereby promote the power output of photovoltaic module.When sunray is radiated at rear row's assembly header board glass surface in addition, light reflection occurs, be projected on front-seat assembly back-panel glass minute surface, light reflection occurs again, thereby the light of a part enters in rear row's assembly again, increase the amount of incident of cell piece to sunray, thereby also promoted the power output of photovoltaic module.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the utility model photovoltaic module structure figure.
