Abstract
The invention discloses a novel insulating back plate for a solar photovoltaic cell, which comprises a structure enhancement layer, a bonding layer, a weather-proof layer and an E bonding layer, wherein the weather-proof layer is compounded on the surface that the bonding layer is back to one side of the structure enhancement layer; and the E bonding layer is directly bonded on the surface of the other side of the structure enhancement layer. The insulating back plate for the solar photovoltaic cell has the advantage that the E bonding layer is directly and thermally compounded with the structure enhancement layer without adhesive, and the combination is better; in a film-making process, the E bonding layer can be directly compounded with the structure enhancement layer so as to reduce cost and increase yield effectively.

Technical field
The present invention relates to the solar-energy photo-voltaic cell technical field, particularly relate to a kind of solar-energy photo-voltaic cell and use insulating back panel.
Background technology
Such as industry knowledge, the overall structure of solar-energy photo-voltaic cell roughly but definitely be not limited to and comprise: framework, be installed on solar energy photovoltaic glass on the framework, be positioned at battery sheet (also claiming silicon chip or silicon plate), hot melt adhesive layer, terminal box and the insulating back panel of solar energy photovoltaic glass below.The order of solar cell package is: photovoltaic glass, hot melt adhesive layer, battery sheet, hot melt adhesive layer and insulating back panel.
Solar-energy photo-voltaic cell is positioned at the back side of solar panel with insulating back panel (be called for short solar energy backboard), and the battery sheet is played protection and supporting role, must have reliable insulating properties, water preventing ability, resistance to ag(e)ing.
The solar energy backboard generally has three-decker, the intermediate structure enhancement layer and be compound in respectively in the middle of outer weathering layer and the internal layer weathering layer on enhancement layer two sides, between said intermediate structure enhancement layer and the weathering layer usually through the adhesive connection.Outer weathering layer need have good anti-environmental attack ability, and the intermediate structure enhancement layer need have the good insulation performance performance, and the internal layer weathering layer also need have with hot melt adhesive layer and have good adhesive property.
Present solar energy backboard is important to exist following problem: use adhesive between middle enhancement layer and the interior E adhesive layer, product cost is increased, process loaded down with trivial details.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of solar energy photovoltaic battery and uses insulating back panel, can when guaranteeing excellent properties, reduce cost, and makes simple.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: provide a kind of solar energy photovoltaic battery to use insulating back panel; Comprise: structure enhancement layer, tack coat, weathering layer and E adhesive layer; Said weathering layer heat is compound in the surface of said tack coat back to a side of structure enhancement layer, and said E adhesive layer directly is combined in the surface of the opposite side of said structure enhancement layer.
In preferred embodiment of the present invention, said structure enhancement layer and tack coat are PETG, and said weathering layer is a Kynoar, and E is bonding to be polyethylene particle coextrusion casting film layer by layer.
In preferred embodiment of the present invention, the thickness of said structure enhancement layer is 180～300 μ m.
