Description

Eliminate anti-dazzle subassembly of mole line

Technical Field

The utility model relates to the technical field of photovoltaic modules, in particular to an anti-glare module capable of eliminating moire fringes.

Background

The existing anti-dazzle component is easy to generate the moire phenomenon, due to the fact that the pattern structures are regularly arranged on the surface of glass on the front face of the anti-dazzle component, when the arrangement of glass pattern arrays is close to that of a metal grid line array structure of a battery piece, after the two close arrays are overlapped, when visible light sequentially passes through the glass pattern arrays and the metal grid line arrays of the battery piece, overlapped stripes (namely the moire phenomenon) of different stripes can be generated visually when people observe the anti-dazzle component, and the stripes can influence the visual effect.

At present, the way to solve the moire phenomenon is: the design of adjusting the pattern structure and the pattern distribution on the front glass surface of the anti-glare assembly can weaken the generation of the moire phenomenon to a certain extent, but cannot completely avoid the moire phenomenon.

But care should be taken to ensure the haze value requirements of this particular encapsulating film.

Further, in the Moire-reduced antiglare assembly: the front side packaging adhesive film is also included; the front glass, the anti-friction grain film, the front packaging adhesive film, the crystalline silicon battery sheet layer, the back packaging adhesive film and the back glass are sequentially stacked from top to bottom.

Further, in the Moire-reduced antiglare assembly: the anti-moire film is arranged on the light-emitting surface of the front glass through a printing or magnetron sputtering process; the anti-moire film is a high-light-transmittance haze film, and the haze value is 15-30%.

Further, in the Moire-reduced antiglare assembly: the anti-moire film is made of PET (polyethylene terephthalate), PP (polypropylene), PVC (polyvinyl chloride), EVA (ethylene-vinyl acetate copolymer), PO (polyethylene terephthalate) or TPU (thermoplastic polyurethane elastomer) and can bear the temperature of not less than 150 ℃.

Further, in the Moire-reduced antiglare assembly: and a layer of irregular patterns for eliminating moire interference is impressed on the anti-moire film, so that the haze value of the anti-moire film is 5-10%. Specifically, the pattern of the anti-moire film can be randomly arranged and irregularly distributed, such as a frosted pattern or other patterns with similar structures.

Further, in the Moire-reduced antiglare assembly: the anti-dazzle patterns are of prismatic structures.
