Description

A kind of two glass solar components
Technical field
The utility model relates to a kind of two glass solar components, belongs to technical field of solar batteries.
Background technology
Conventional fossil fuel approach exhaustion day by day, in existing sustainable energy, solar energy is undoubtedly the most clean, the most general and most potential alternative energy source of one.Device of solar generating is also called solar cell or photovoltaic cell, solar energy can be directly changed into electric energy, and its electricity generating principle is the photovoltaic effect of based semiconductor PN junction.
Along with the progress of technology, there is two glass solar components, all adopted glass plate before and after it, therefore there is better light transmission and efficiency.Along with the reduction of glass cost in industry, and for the lifting that assembly reliability requires, two glass assemblies are more and more subject to the favor in market.Because two glass assembly itself has very large resistance to mechanical load-carrying ability, consider the reason of the aspect such as cost and maintenance, often market requires that two glass assembly is the design without frame.Existing pair of glass solar components is by glass 1-EVA2(ethylene-vinyl acetate copolymer)-cell piece-EVA-glass 1 forms, shown in accompanying drawing 1 ~ 3.But experiment proves, traditional encapsulating material EVA has the needs promoted further in reliability.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of two glass solar components.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of two glass solar components, comprises the glass-POE encapsulated layer-cell piece-POE encapsulated layer-glass from bottom to top set gradually;
The surrounding of described assembly is also provided with edge-sealing rubber strip, and described edge-sealing rubber strip is butyl rubber.
Above, the up-down structure of described pair of glass solar components still continues to use prior art, just instead of traditional EVA with POE encapsulated layer.
The surrounding of described pair of glass solar components is also provided with edge-sealing rubber strip, namely carries out edge sealing by adhesive tape to assembly, thus further increases the block-water performance of assembly.
The utility model adopts the better butyl rubber of block-water performance to carry out edge sealing, thus makes assembly have better block-water performance.
Due to POE(ethylene-octene copolymer) comparatively EVA there is better reliability advantage, adopt POE encapsulating material to replace EVA.Meanwhile, in order to the water resistance at stiffener assembly edge, adopt the better butyl rubber edge sealing of block-water performance.
In technique scheme, the width of described edge-sealing rubber strip is 8 ~ 15mm.
Preferably, the width of described edge-sealing rubber strip is 8 ~ 12mm.
In technique scheme, the light transmittance of described glass is more than or equal to 92%.
In technique scheme, the reflectivity of described glass is more than or equal to 91%.
In technique scheme, the thickness of described glass is 0.85 ~ 3.2mm.
In technique scheme, described glass is high toughened glass or half tempered photovoltaic glass thoroughly.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model adopts POE encapsulated layer to replace existing EVA, adopts the better butyl rubber of block-water performance to carry out edge sealing simultaneously, not only increases the reliability of assembly, and further increase the water resistance of module edge;
2. there is sizable raising the aspects such as structure of the present utility model is split cell piece anti-hidden, anti-assembly is bending, can by under this solar components application to most of environment.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
See shown in Fig. 4 to 6, a kind of two glass solar components, comprises the glass 1-POE encapsulated layer 4-cell piece-POE encapsulated layer-glass 1 from bottom to top set gradually; Described cell piece is non-anti-PID solar cell;
The surrounding of described assembly is also provided with edge-sealing rubber strip 3, and described edge-sealing rubber strip is butyl rubber.
The width of described edge-sealing rubber strip is 10mm.
The light transmittance of described glass is more than or equal to 92%.The reflectivity of described glass is more than or equal to 91%.
The thickness of described glass is 3.2mm.Described glass is high toughened glass thoroughly.
Because edge adopts butyl rubber edge sealing, therefore the length of POE and wide cut can suitably reduce.Butyl rubber wide cut 10mm, also can reduce POE consumption simultaneously, and the every limit of POE can than original narrow 13mm, and the gap reserving 3mm is overflowed for POE during lamination.
Embodiment two:
A kind of two glass solar components, comprises the glass-POE encapsulated layer-cell piece-POE encapsulated layer-glass from bottom to top set gradually; Described cell piece is anti-PID solar cell;
