Description
Technical field
The utility model designs photovoltaic module field, and in particular to a kind of imbrication component.
Background technique
Solar energy is widely used and develops as a kind of renewable energy, the extensive use of photovoltaic technology, so that photovoltaic
The demand of component is also quickly increasing, but conversion ratio and reliability are the maximum technology barriers for restricting theCourse of PV Industry.
The one kind of imbrication component as photovoltaic module refers to a piece of conventional solar cell using dicing technique (such as laser)
Piece is cut into 5 or 6 battery slices, and reusing conducting resinl, staggered superposition is bonded to form battery up and down by certain amount battery slice
String, and battery strings are connected in series or in parallel to the component being packaged by busbar.Imbrication component replaces conventional photovoltaic component to adopt
The cell piece piece spacing 2-3mm that need to retain when welding cell piece with interconnecting strip, this improves component unit area output works
Rate.
During imbrication establishment of component, interconnecting strip is first welded in the battery of the two panels end to end slice of every string battery strings, then weld
Busbar realizes all battery strings series-parallel circuit designs.Specifically, firstly, the interconnecting strip of positive battery string and battery slice are carried on the back
Face welding, interconnecting strip and battery slice the front welding of negative battery string；Then busbar bending that will be welded with interconnecting strip then,
Be sliced the back side to battery, and be encased inside between battery slice is busbar isolating bar by battery slice and busbar insulate every
From, and with electric iron spot welding busbar and isolating bar to be fixed on the positioning.
Mainly there is following problem during existing imbrication component typesetting:
(1) it when busbar bending to battery being sliced the back side, needs by certain tooling, while to the skill of operation employee
More demanding, the misoperation of energy is very easy to cause two rows of batteries slice cracks or sliver end to end, increases battery strings and reprocess into
This.
(2) isolating bar thickness is generally 0.2~0.3mm, and busbar is two rows of electric end to end in every string with a thickness of 0.1~0.2mm
Pond be sliced the back side, due to bending busbar be superimposed with isolating bar will form with a thickness of 0.3~0.5mm step, in this way in imbrication
After component lamination, two steps with obvious difference in height can be presented in module backside edge, meanwhile, in lamination process, 0.3~
0.5mm step will increase the crack and sliver of two rows of battery slices end to end, and imbrication component after lamination is caused to degrade or scrap.
(3) when using electric iron spot welding bending busbar and isolating bar, or carrying out battery slice or busbar replacement repair welding,
If electric iron cleaning is not in time or operation employee's operation technique is unfamiliar with, after spot-welded, it is very easy to residual on busbar
It stays scolding tin slag, overlap and La Xi etc. to weld residue, it is hidden to will cause two rows of battery slices end to end after these welding residue laminations
It splits and sliver, imbrication component after lamination is caused to degrade or scrap.
(4) in imbrication component typesetting, all imbrication battery strings are uniformly laid with by 3~4mm of spacing string spacing, and half is positive
Grade battery strings area, half are negative a grade battery strings area.Negative grade battery strings head battery is sliced positive edge and has (1.5~2)
Mm*156mm area is interconnected item welding and covers (i.e. battery slice front is welded with interconnecting strip, and interconnecting strip can be seen), institute
There is the positive edge of positive grade battery strings tail portion battery slice also to have (1.5~2) mm*156mm area and is interconnected item welding screening
Firmly (i.e. battery slice front is welded with interconnecting strip, and interconnecting strip can be seen), and all negative grade battery strings tail portion batteries are sliced
Interconnecting strip welding is not had with positive grade battery strings head battery slice covers battery slice (i.e. the battery slice back side and interconnecting strip
Welding, interconnecting strip can not be seen), therefore will cause component typesetting asymmetry, influence the overall beautiful performance of component.
Authorization Notice No. is that the utility model patent of CN206524340U discloses a kind of efficient imbrication component, and cell piece is in
The cell piece of row arrangement, locating column is arranged and is connected in parallel in imbricate, using the connection type of whole parallel circuits, can drop
Low internal resistance loss, lifting assembly output power；Welding busbar is provided in backboard, the welding busbar includes two
Lateral busbar and a longitudinal busbar；The cell piece first and last row institute that two lateral busbars are separately positioned on ranks arrangement is right
In the component backboard answered.The utility model proposes imbrication component use new-type typesetting, whole circuit connecting modes in parallel drops
Low component internal resistance loss, improves component output power, but there is no the imbrication component typesettings for solving to state in background technique
4 problems present in journey.
