Embodiment

The embodiment of the utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning Same or similar element is represented to same or similar label eventually or there is same or like element.Below by ginseng The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and cannot be construed to the utility model Limitation.

The utility model provides a kind of embodiment of flexible unit solar cell, it should be noted that, the present embodiment is By taking flexible CIGS solar film as an example, certainly, the utility model can be applied to the flexibility of other materials by those skilled in the art Monomer solar cell, does not limit this utility model.

Referring to shown in Fig. 1 and Fig. 2, the present embodiment has specifically included CIGS flexible chips 1, the first busbar 2, second confluence Bar 3, transparent encapsulated layer 4 and fluid sealant 5.Wherein, the first busbar 2 is connected with the cathode of CIGS flexible chips 1, the second confluence Bar 3 is connected with the anode of CIGS flexible chips 1, and the effect of the two is that electrode is led to outside batteries, so the first busbar 2 It is the good tin plating copper bar of electric conductivity with the second busbar 3, also need to further illustrate here is that the utility model uses busbar Rather than common more narrower conducting wire band structure, thus it will be appreciated that the busbar of the utility model compared to conductor strip, its Structural strength and transmission performance are more excellent；And transparent encapsulated layer 4 can then be covered in 1 and first busbar 2 of CIGS flexible chips, The surface of second busbar 3, that is to say enable the transparent encapsulated layer 4 be coated on 1 and first busbar 2 of CIGS flexible chips, Outside second busbar 3, and fluid sealant 5 is scribbled in the edge that transparent encapsulated layer 4 and CIGS flexible chips 1 join, it is acted on It is to make the CIGS flexible chips 1 of steam and inside in extraneous air completely isolated, thus, in practical operation, transparent enclosure Layer 4, which can be selected, has high light transmittance, waterproof, uvioresistant and age inhibiting ETFE (ethylene tetrafluoroethylene) material, and fluid sealant 5 Then to consider its heat-resisting, resistance to steam, and have shock-absorbing and electrical insulation capability etc., in a preferred solution of the present embodiment, use Be the butyl rubber for having good repellence to steam.

Further illustrate, the CIGS flexible chips 1 in Fig. 1 and Fig. 2 embodiments, its anode and cathode are set respectively In the front and back of CIGS flexible chips 1, therefore, the first busbar 2, the second busbar 3 can be respectively placed in CIGS flexible cores The two sides of piece 1, it is specific in operation, the first busbar 2 can be regarded as to the two parts being connected to each other, the first contact site 21 and first Extension 22, and the second busbar 3 is then similarly, includes the second contact site 31 and the second extension 32 being connected to each other, and Embodiment in reference chart, the length of the first contact site 21 can be more than the first extension 22, and the length of the second contact site 31 can be with More than the second extension 32, specifically, the first contact site 21 and the second contact site 31 are respectively adopted and penetratingly from first to last cover Formula connection mode, with the plate-shaped positive of CIGS flexible chips 1 and all raised back-shaped needle-shaped anode completely, be closely contacted, And the first extension 22 and the second extension 32 then each extend over away, and positioned at CIGS flexible chips 1 outside, easy to External test facility is electrically connected.At the same time, transparent encapsulated layer 4 can then be covered in front and the back of the body of CIGS flexible chips 1 Face, and the edge of the transparent encapsulated layer 4 in front and back is all coated with fluid sealant 5.

It can be seen from the above, flexible CIGS monomer solar cell provided by the utility model has the following advantages that：

1) waterproof enclosure coordinated by transparent encapsulated layer 4 and fluid sealant 5 is handled, and improves the stability of battery chip, Security.

2) positive and negative anodes are drawn by busbar, facilitates the test of flexible CIGS single battery, be more convenient flexible CIGS The expansion and application of monomer solar cell；

3) the flexible CIGS monomer solar battery structure that the utility model proposes, the flexible battery with monolithic thin film form simulation The encapsulation of component, thus the utility model can replace complete assemblies to carry out light burn-in test, so as to save related resource and cost.

The structure, feature and effect of the utility model are described in detail based on the embodiments shown in the drawings, but The above is only the preferred embodiment of the present invention, it is necessary to explain, involved by above-described embodiment and its preferred embodiment Technical characteristic, those skilled in the art can not depart from, not change the mentality of designing and technique effect of the utility model On the premise of, reasonably combination collocation is into a variety of equivalents；Therefore, the utility model does not implement model to be limited shown in drawing Enclose, the change that every conception according to the utility model is made, or be revised as the equivalent embodiment of equivalent variations, still without departing from saying When bright book is with illustrating covered spirit, it should be within the protection scope of the present utility model.
