Background technology
Encapsulate crystalline silicon solar cell modules at present; usually adopt the monolithic solar cell; its front is obliquely installed sunward, and the front is subjected to light; also having can printing opacity double glazing crystalline silicon solar cell modules; but because of accumulated snow; ponding; sand and dust accumulation and birds infringement etc. shut out the light; influence the raising of generating efficiency; reason owing to illumination ageing; will yellowing about 2 years; light transmittance obviously descends; the solar module of this class encapsulation monolithic crystalline silicon form; also there is the mechanical protection performance; sealing; problem such as prevent to pollute and humidity resistance is relatively poor; the place is set and removes attachment and all need certain condition, its useful life; generating efficiency and reliability are a greater impact.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide and be fit to and the use that becomes one of works such as enclosure wall, wall, pillar equipment, adopt new encapsulating structure, longer service life, daylighting, the design impact of performance more fill part, improve a kind of two-sided lighted power generation vertical setting photovoltaic wall plate of solar cell generating efficiency.
The object of the present invention is achieved like this: a kind of two-sided lighted power generation vertical setting photovoltaic wall plate, it is by low iron toughened glass A1.1, EVA resin molding A1.2, monocrystalline silicon battery group sheet 1.3, EVA resin molding B1.4, low iron toughened glass B1.5 and terminal box 1.6 constitute, with monocrystalline silicon battery group sheet 1.3 in good order the putting of connecting, with EVA resin molding A1.2 and EVA resin molding B1.4 battery pack sheet two sides is folded again, the low iron toughened glass in two sides is carried out hot sealing at the skin of two EVA resin moldings, so just constitute two-sided lighted power generation vertical setting photovoltaic wall plate.
The front and back of described battery pack has adopted identical excellence design.
Described battery pack adopts the monocrystalline silicon piece of high conversion efficiency.
Described battery pack is N
+PP
+Structure, front electrode 2.2 is a negative pole, forms overleaf and positive identical shaped electrode, backplate 2.3 is anodal.Form quadrangular pyramid 2.7 structures at random at front and back, improved the light sealing effect.
Described battery pack is of a size of 125mm * 125mm, and thickness is 240 μ m, has realized the slimming of large-sized battery pack, saves resource.
Adopt the two-sided lighted power generation vertical setting photovoltaic wall plate of above-mentioned encapsulating structure; adopt unique production technology to make boron diffusion back surface field two sides battery pack technology; realized that front and back is subjected to light; can efficient power generation; surface coverage higher mechanical strength and the low iron toughened glass of the protective capability that conforms owing to just carrying on the back; make it have the good light transmittance energy; give full play to the characteristic that the front and back two sides is subjected to light and generating; realize efficient power generation; daylighting; the design performance is outstanding; weatherability is outstanding; permanent useful life; can vertically be provided with; realized being provided with the saving spatialization in place; even vertical the setting; also can be subjected to light to be obliquely installed the same degree of mode with single face generates electricity; with orientation-independent is set, the energy output in 1 year keeps necessarily not being subjected to because of accumulated snow substantially; the influence that sand and dust are piled up and birds shut out the light; compared by the light mode of being obliquely installed with single face; these attachments of easier removing, sealing; anti-mechanical damage; moisture resistance is wet; performances such as antipollution are also very high, and the present invention is with low cost; make simple and easy; be convenient to penetration and promotion, with enclosure wall; wall; works such as pillar equipment become one, and are applicable to various uses.
