In description of the invention, unless otherwise indicated, the meaning of " plurality " is two or more.
On the one hand, the embodiment of the present invention provides a kind of repair method of solar panel laser scoring exception, by swashing
Solar panel is divided into the monocell of multiple series connections by photoetching line along first direction, referring to Fig. 7 and Fig. 8, including：Step
The rapid scribe line position that the first short side insulated wire 51 1) is redefined according to the position of laser scoring abnormal area A；Step 2) institute
Again insulated wire is delineated at the scribe line position of the first short side insulated wire 51 redefined, obtains the second short side insulated wire 51 ', with
By laser scoring abnormal area A be isolated in the second short side insulated wire 51 ' and in addition to the first short side insulated wire 51 remaining is former absolutely
Edge line (short side insulated wire be denoted as 51 and long side insulated wire be denoted as 52) except the region that is enclosed；Wherein, the first short side is exhausted
Edge line 51 be former insulated wire (short side insulated wire be denoted as 51 and long side insulated wire be denoted as 52) in be parallel to first direction appoint
It anticipates an insulated wire.
Wherein, it should be noted that since solar panel is rectangle, usually the width side along solar panel
Solar panel is divided into the monocell 11 of multiple series connections to progress laser scoring, correspondingly, along solar energy
The insulated wire that the width direction of solar panel extends is short side insulated wire 51, and will be extended along the length direction of solar panel
Insulated wire be denoted as long side insulated wire 52.
In practical applications, usually laser scoring is observed by microscope, to obtain laser scoring abnormal area A
Position, as shown in fig. 6, be laser scoring abnormal area A microscope view.
The embodiment of the present invention provides a kind of repair method of solar panel laser scoring exception, by according to laser incising

Continue towards the direction far from the first short side insulated wire 51 at edge from laser scoring abnormal area A far from the first short side insulated wire 51
The position that translation pre-determined distance is reached.
Wherein, in plated film, usually only occur in an edge placement of substrate 1 around plating, so, near laser
The short side insulated wire of groove abnormal area A is the first short side insulated wire 51.
In embodiments of the present invention, after determining the first short side insulated wire 51, by identified first short side insulated wire
51 scribe line position is determined as the edge from laser scoring abnormal area A far from the first short side insulated wire 51 towards far from first
The direction of short side insulated wire 51 continues to translate the position that pre-determined distance is reached, can be as far as possible by laser scoring abnormal area A
Keep apart with normal region, avoids laser scoring exception bring short circuit problem.
Wherein, in actual operation, the seat to be translated can be calculated by the method for inputting pre-determined distance to computer
Mark, by being moved to solar panel, by the groove of the first short side insulated wire 51 identified on solar panel
Position, which is moved to, to be calculated at coordinate position obtained.
Preferably, pre-determined distance 2-3mm.
In another embodiment of the present invention, by laser scoring twice in the first short side insulated wire 51 redefined
Again insulated wire is delineated at scribe line position, obtains the second short side insulated wire 51 '.
It specifically includes：Referring to Fig. 9, photoelectric conversion layer 3 and back electrode conductive film layer 4 are removed by first time laser scoring,
Referring to Figure 10, electrodes conduct film layer 2 before being removed by second of laser scoring.
In process of production, when delineating insulated wire, electrodes conduct film layer 2 before first time laser scoring removes is first passed through, then
Photoelectric conversion layer 3 and back electrode conductive film layer 4 are removed by third time laser scoring, when reprocessing, and is delineated in production process
The step of insulated wire, is exactly the opposite, that is, first passes through first time laser scoring and remove photoelectric conversion layer 3 and back electrode conductive film layer 4,
Electrodes conduct film layer 2 before being removed again by second of laser scoring, to form the second short side insulated wire 51 '.
Wherein, it should be noted that when insulated wire delineates exception, can equally be reprocessed according to above step,
To delineate insulated wire again.
On the other hand, the embodiment of the present invention provides a kind of solar panel, and referring to figs. 7 and 8, solar panel is logical
It crosses laser scoring and is divided into multiple monocells 11 being sequentially connected in series along first direction, solar panel includes：Laser
