Abstract
The utility model discloses a photovoltaic assembly, including polylith photovoltaic cell piece and conductive strips, conductive strips weld the obverse and reverse of adjacent photovoltaic cell piece respectively to form the cascaded structure of adjacent photovoltaic cell piece, be close to the clearance department between the two adjacent photovoltaic cell pieces, edge that front or the reverse side welded of conductive strips on photovoltaic cell piece wherein plays solder joint and this photovoltaic cell piece leaves the certain distance, and reverse side or the edge that play solder joint and this photovoltaic cell piece of openly welding of conductive strips on another photovoltaic cell piece leaves the certain distance. The utility model discloses can effectively avoid beginning to crack or recessive crackle from the edge because of the thermal stress leads to the battery piece to extension photovoltaic assembly's life stops the potential safety hazard.
Description
Technical field
This utility model relates to field of photovoltaic technology, particularly relates to a kind of photovoltaic module.
Background technology
Along with the development of China's economy, living standards of the people and quality mouth benefit improve, meanwhile, energy
Also the mouth benefit of source crisis and environmental problem highlights.The extensively application of solar energy power generating embodies and can hold
The supervention exhibition energy and the theory of recycling economy, readjust the energy structure and ensure that energy security is improving and protecting field
Ball border and occupy mouth benefit consequence in guaranteeing the sustainable development of human society.China's photovoltaic
Industry has caught historical opportunity to develop, continues to optimize production technology, improves management system, improves product
Quality, oneself has a higher competitiveness to the photovoltaic products of current China in the world, but during using also
It is found that some problems, such as: crackle or latent crack easily occurs in the cell piece of photovoltaic module, so
Just shorten the service life of photovoltaic module.
There is the phenomenon of crackle or latent crack through during producing, transporting and use in cell piece, for
Appearance those skilled in the art in prevention cell piece crackle have made a lot of research and have proposed some technical sides
Case is to overcome these problems, such as: the utility model patent of Application No. 201120077268.7 discloses name
For the technical scheme of " a kind of anti-hidden split photovoltaic module ", the program by arrange aluminum alloy frame, laminate layer part with
And reinforcement as reinforcement feature thus suppresses the vibrations in transportation, and then avoid photovoltaic module in transport
During crackle occurs；The utility model patent of Application No. 201310546302.4 discloses a kind of entitled
The technical scheme of " Hidden-crack-preventdouble-glass double-glass module ", claims that can solve photovoltaic module generation in production process splits
Stricture of vagina or the problem of latent crack.
In addition to producing and in transport, photovoltaic module can crack, the crackle or hidden in use produced
Property crackle is also the most relatively conventional phenomenon.The cell piece series connection of conventional photovoltaic assembly, uses conduction at present
Adjacent cell sheet positive and negative is carried out high temperature series welding in the way of full weld by band, and this mode is due to the battery that expands with heat and contract with cold
Sheet produces thermal stress effects with conductive strips, causes cell piece to crack or latent crack, makes photovoltaic module exist
Use the middle lost of life or produce potential safety hazard.
Utility model content
For solving problem above, this utility model provides one can be prevented effectively from because thermal stress causes cell piece
The photovoltaic module cracked is started from edge.
Above-mentioned purpose of the present utility model is realized by following technical proposal:
A kind of photovoltaic module, including polylith photovoltaic cell and conductive strips；Conductive strips are welded to adjacent light
The obverse and reverse of volt cell piece, thus form the cascaded structure of adjacent photovoltaic cell sheet；
The obverse and reverse welding on adjacent two pieces of photovoltaic cells of the described conductive strips, near adjacent two light
Gap location between volt cell piece, a solder joint of the front welding on conductive strips one piece of photovoltaic cell wherein
Certain distance is left, conductive strips reverse side weldering on another block photovoltaic cell with the edge of this photovoltaic cell
The edge playing solder joint and this photovoltaic cell connect leaves certain distance.
Further, described photovoltaic cell is crystal silicon photovoltaic battery.
Further, described conductive strips are the tin plating material of cuprio.
By above technical scheme, this utility model has the advantages that and is: can be prevented effectively from because heat should
Power causes cell piece to start from edge to crack or latent crack, thus extends the service life of photovoltaic module,
Stop potential safety hazard.

Detailed description of the invention
Describe the technical solution of the utility model below in conjunction with the accompanying drawings with embodiment in detail, but protection domain is not
It is limited to this.
Embodiment: a kind of photovoltaic module, as shown in figures 1-4, including polylith photovoltaic cell 1 and conductive strips 2.
Conductive strips 2 are welded to the obverse and reverse of adjacent photovoltaic cell sheet, thus form adjacent photovoltaic cell sheet 1
Cascaded structure.
Wherein, the conductive strips 2 obverse and reverse Welding Structure on adjacent two pieces of photovoltaic cells is as follows:
At gap 3 between adjacent two photovoltaic cells, conductive strips 2 one block of photovoltaic cell (light wherein
Volt cell piece 1) on the edge playing solder joint and this photovoltaic cell that welds, front (or reverse side) leave
Certain distance, makes conductive strips 2 be formed with the surface of photovoltaic cell 1 on this segment distance and reserved does not welds
4；The conductive strips 2 reverse side (or front) welding on another block photovoltaic cell (photovoltaic cell 2 12)
The edge playing solder joint and this photovoltaic cell leave certain distance, this segment distance makes conductive strips 2 and light
The surface of volt cell piece 2 12 is formed to reserve does not welds 4, thus is prevented effectively from because thermal stress causes battery
Sheet starts from edge to crack or latent crack.
Photovoltaic cell 1 therein is crystal silicon photovoltaic battery, and conductive strips 2 are the tin plating material of cuprio.
The foregoing is only preferred embodiment of the present utility model, be not limited to utility model.To the greatest extent
Wood utility model has been described in detail by pipe with reference to previous embodiment, and the technical staff for wood field comes
Saying, the technical scheme described in foregoing embodiments still can be modified by it, or to wherein part
Technical characteristic carries out equivalent.Embodiment is only work of the present utility model is described as a example by tea packaging
Making principle, it is not limited in the packaging of Folium Camelliae sinensis.Within all spirit in utility model and principle, made
Any modification, equivalent substitution and improvement etc., within should be included in the protection domain of utility model.
