Description
Technical field
The utility model relates to a kind of crack resistence solar battery sheet.
Background technology
Tin in the process of welding and welding of battery film on welding can melt, and forms alloy with the main gate line of cell piece, and then is connected by cell piece, forms battery strings.
See Fig. 1, the main gate line of traditional solar battery sheet extends to cell piece edge, when current welding and welding of battery film, welding can be soldered to the edge of cell piece, when carrying out subsequent operation to battery strings, the situation that battery strings can occur bending and deformation, welding flexural deformation can cause cell piece to split from edge, and then causes assembly fragment rate and hidden to split rate higher.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and reduces assembly fragment rate and the hidden crack resistence solar battery sheet splitting rate.
The purpose of this utility model is achieved in that
A kind of crack resistence solar battery sheet, it comprises cell piece body, cell piece body is provided with the secondary grid line of many main gate line of vertically arranging and many transverse arrangement of turbo, it is characterized in that the two ends up and down that the two ends up and down of described main gate line extend to cell piece edge inside second to the secondary grid line place of the six roots of sensation or described main gate line extend to inside 1mm ~ 10mm place, cell piece edge, the secondary grid line place of the upper and lower outer end of main gate line disconnects, and is provided with the connecting line extended out between the right and left line at the upper and lower two ends of main gate line and first secondary grid line at cell piece edge.
Preferred as one, the large 0 ~ 5mm of gap ratio main gate line width that secondary grid line disconnects.
Preferred as one, connecting line is straight line, circular arc line or broken line.
Preferred as one, the angle of connecting line and main gate line is 0 ° ~ 60 °.
Preferred as one, the width of connecting line is 0.01mm ~ 0.5mm.
Compared with prior art, the beneficial effects of the utility model are:
The utility model crack resistence solar battery sheet avoids welding to be welded to cell piece edge from structure, and then when battery strings can be prevented to bend, the stressed generation in cell piece edge is hidden splits and fragment.Therefore this crack resistence solar battery sheet has reduction assembly fragment rate and the hidden advantage splitting rate.
