Glass, so weight is big, carries inconvenient.Simultaneously because can not solve due to power loss caused by light leak between cell piece, so
Never form large-scale volume production.With the continuous progress of technology, double glass photovoltaic modulies are increasingly popularized, solar double-glass assemblies warp
Gone to finally after platform before platform after breeding for many years.
The structure of solar double-glass assemblies is to be followed successively by protecgulum glass sheet-upper strata encapsulating material-cell piece-lower floor encapsulation from top to bottom
Material-bonnet glass sheet and terminal box.Bypass diode being configured with terminal box, being sent out during for preventing that cell piece is blocked by shadow
Give birth to hot spot effect and wreck.General double glass photovoltaic modulies are installed on solar energy smart window, solar energy wayside pavilion and glass architecture
Ceiling, and glass curtain wall etc., larger terminal box is installed on the back side of component, is an impediment to the attractive in appearance of component, and influence
The light transmittance of component.Terminal box is arranged on module backside, and its poor heat-sinking capability causes tray interior to have higher temperature,
This can directly influence the cell piece in this region, cause the mismatch between cell piece, reduce the power output of component.Although wiring
Bypass diode in box can protect cell piece when blocking generation, but due to bypass diode Limited Number, in such case
Lower component still has larger power loss.
The content of the invention
For problem above, the purpose of this utility model is to provide a kind of double glass photovoltaic modulies of built in bypass diode,
By setting groove on glass, more bypass diode is built in component internal, optimal protection is provided component
Function, while ensureing that component still has larger power output when occurring shadow occlusion, saves the terminal box of module backside in addition,
Reduce the cost of component.
The utility model is so achieved, a kind of double glass photovoltaic modulies of built in bypass diode, including preposition
Glass, preposition EVA adhesive film, solar battery sheet, rearmounted EVA adhesive film, rearmounted glass, it is characterised in that：Described rearmounted glass
Front is provided with several grooves, each groove and is provided with a bypass diode, and described rearmounted glass back is provided with electricity
Cable and connector.
Described solar battery sheet is composed in series multiple solar cell strings using welding, in the upper and lower part of component
Each solar cell string is connected using some convergent belts respectively.
Described each bypass diode respectively with corresponding solar cell connection in series-parallel connect, bypass diode positive pole and
Negative pole connects the negative pole and positive pole of correspondence solar cell string respectively.
Described bypass diode is arranged on non-solar cell batteries panel region.
Described bypass diode is paster Schottky diode.
Described rearmounted glass is provided with two through holes, and convergent belt leads to rearmounted glass back and and cable from this through hole
Connection.
The beneficial effects of the utility model are as follows：The groove of bypass diode is placed by being set in rearmounted glass front,
The bypass diode in terminal box that general components can be used is introduced to component internal, on the one hand can be set in component internal
More bypass diodes are put, optimal defencive function is provided solar battery sheet, at utmost reduction blocks defeated to component
The influence gone out, ensures the peak power output of component as far as possible；On the other hand the terminal box of module backside, lifting group can be saved
The cosmetic look of part, reduces the cost of component；Further, since solar double-glass assemblies have good heat-sinking capability, can in time by
The heat that component internal bypass diode is produced is conducted to external environment condition, reduces the junction temperature of bypass diode, it is ensured that bypass two
The reliability of pole pipe and life-span, reduce the incidence of failure.
Brief description of the drawings
Fig. 1 is diagrammatic cross-section of the present utility model.
Fig. 2 is schematic rear view of the present utility model.
In figure, 1 is front glass, and 2 be preposition EVA adhesive film, and 3 be solar battery sheet, and 4 be rearmounted EVA adhesive film, after 5 are
Glass is put, 6 be groove, and 7 be bypass diode, and 8 be cable, and 9 be connector, and 10 be welding, and 11 be solar cell string, and 12 are

Embodiment
To further appreciate that technical characteristic of the present utility model and content, illustrate below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, double glass photovoltaic modulies of a kind of built in bypass diode, including front glass 1, preposition EVA
Glued membrane 2, solar battery sheet 3, rearmounted EVA adhesive film 4, rearmounted glass 5, described rearmounted glass front are provided with several grooves 6,
A bypass diode 7 is provided with each groove, described rearmounted glass back is provided with cable 8 and connector 9.
Described solar battery sheet is composed in series multiple solar cell strings 11 using welding 10, on the top of component and
Each solar cell string is connected using some convergent belts 12 respectively bottom.It is arranged on each side in rearmounted glass groove
Road diode is connected with corresponding solar cell connection in series-parallel respectively, and the negative pole of bypass diode positive pole and solar cell string connects
Connect, bypass diode negative pole is connected with the positive pole of solar cell string, so bypass two when solar battery sheet normal work
Pole pipe is in reverse-biased；And work as part solar battery sheet in the solar cell string in parallel with bypass diode and be blocked
When, in order to prevent these cell pieces from cause thermal damage occurred because of hot spot effect, bypass diode now in parallel will forward conduction,
The electric current for flowing through the cell piece that is blocked originally is set to be bypassed diode shunting.The bypass diode is preferably the pole of paster Schottky two
Pipe.Described rearmounted glass is provided with two through holes 13, and two convergent belts after each solar cell string series connection draw from this through hole
Go out to rearmounted glass back and be connected with external cable.
The utility model places the groove of bypass diode by being set in rearmounted glass front, can be by bypass diode
Component internal is embedded in, and the quantity of bypass diode and position can arbitrarily be set according to actual needs, therefore can be by
The solar battery sheet that total quantity is fixed is divided into more solar cell strings, even if the solar battery sheet in component is by shade
Block, but it is this block the influence very little brought, so component still has very big power output in this case.Due to component
Inside is provided with bypass diode, and bypass diode is arranged on non-battery panel region, therefore can remove the general components back of the body
The terminal box that face is used, reduces the cost of component to a certain extent, while the heat that terminal box is produced causes cell piece mismatch
This influence has not been existed yet, and the power output of component is improved indirectly.Other solar double-glass assemblies make by good heat-sinking capability
Obtaining bypass diode has lower junction temperature, it is ensured that the reliability of bypass diode and life-span, reduce the incidence of failure,
Improve the reliability of component.
Person skilled in the art is it should be appreciated that the embodiment of the above is intended merely to illustrate that this practicality is new
The purpose of type, and be not used as limiting of the present utility model, as long as in essential scope of the present utility model, to described above
Change, the modification of embodiment will all fall in the range of claim of the present utility model.
