Abstract
The utility model discloses a novel photovoltaic assembly including low iron super-white tempered glass (1), an upper hot-melting film (2), a battery piece (3), a lower hot-melting film (4) and a backing plate (5), wherein the hot-melting films are PE films. The novel photovoltaic assembly provided is high in mechanical strength and good in resisting PID capacity, and greatly improves the performance of the assembly.
Description
Technical field
The utility model relates to a kind of novel photovoltaic module, belongs to photovoltaic module technical field.
Background technology
The multiplex EVA of photovoltaic module is in the market as encapsulating material, EVA is that ethene and vinyl acetate become EVA encapsulating film after polymerization, because the side chain of this film has individual fat base, between main chain, gap is larger, the tensile strength that causes EVA, specific insulation and anti-PID performance all decline to some extent, usually, Va content is in the tensile strength of 30% EVA at 20～40MPa, and the order of magnitude of specific insulation is 10
12, cannot test by PID, affected mechanical strength and the safety in utilization of assembly.
Utility model content
The problem existing for above-mentioned prior art, the utility model provides a kind of novel photovoltaic module, can improve the mechanical strength of assembly, specific insulation and anti-PID performance.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of novel photovoltaic module, and its structure is followed successively by from top to bottom: low iron ultrawhite toughened glass, upper hot melt film, solar battery sheet, lower hot melt film, backboard, described hot melt film is PE film.
Further, described PE film is high density polyethylene (HDPE) (HDPE).
Further, described PE film thickness is between 0.40～0.60mm.
Further, the order of magnitude of the specific insulation of described PE film is 10
15above.
The beneficial effects of the utility model are: the tensile strength of PE film is more than 50MPa, and the order of magnitude of specific insulation is 10
15above, and have good resistance PID ability, significantly promoted mechanical strength and the specific insulation of assembly, anti-PID performance also gets a promotion.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model novel photovoltaic module.
In figure: 1, low iron ultrawhite toughened glass, 2, upper hot melt film, 3, solar battery sheet, 4, lower hot melt film, 5, backboard.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Novel photovoltaic module, as shown in Figure 1, its structure is followed successively by from top to bottom: low iron ultrawhite toughened glass 1, upper hot melt film 2, solar battery sheet 3, lower hot melt film 4, backboard 5, described hot melt film is PE film, described PE film is high density polyethylene (HDPE) (HDPE), described PE film thickness is between 0.40～0.60mm, and the order of magnitude of the specific insulation of described PE film is 10
15above.
The tensile strength of HDPE film is generally more than 50MPa, and the order of magnitude of specific insulation can reach 10
15above, and have the potential induction of good resistance PID(to lose efficacy) ability, significantly promoted mechanical strength and the specific insulation of assembly, anti-PID performance also gets a promotion.
