On photovoltaic module, as a rule, the front main grid line and the back side back electrode of battery sheet are symmetrical, and the width of general front main grid line is 1.5mm～2.1mm, the back electrode width is 3mm～4mm, and back electrode mainly is that the side-play amount of considering welding designs than main grid live width.In order to improve cell and component power, the main grid line can be narrowed down, increase light-receiving area, also can the main grid line constant and widen back electrode and back side interconnecting strip welding, the area by back side interconnecting strip increases and reduces series resistance, thereby improves the assembly power output.But common welding is a plate-like, is used to after the cutting to connect up and down that the width of battery sheet is identical, if the interconnecting strip of main grid line is with narrow, the interconnecting strip of back electrode is irrealizable with wide at present conventional welding.Also can segmentation weld, but inconvenient operation.
Summary of the invention
The technical problem to be solved in the present invention is: shortcoming and deficiency in order to solve above-mentioned existence provide a kind of novel interconnecting strip and matching used battery sheet.
The technical solution adopted for the present invention to solve the technical problems is: a kind of interconnecting strip, have banded body, and an end of body is thin portion, an other end is wide portion.
Interconnecting strip is the T type, and the vertical portion of T type interconnecting strip is divided into thin portion, and horizontal component is wide portion.
Because the processing of T type welding is difficulty relatively, therefore also can change the L type into, interconnecting strip is the L type, and the vertical portion of L type interconnecting strip is divided into thin portion, and horizontal component is wide portion.
Further, the thin portion of described T type interconnecting strip is wide to be 1.0～2.5mm, and wide wide is 3～6mm.
The thin portion of described L type interconnecting strip is wide to be 1.0～2.5mm, and wide wide is 3～6mm.
Battery sheet with the supporting a kind of special back electrode of L type interconnecting strip, have battery sheet front that contains the main grid line and the cell back face that contains back electrode, back electrode offsets to one side with respect to the main grid line, guarantee that simultaneously back electrode one side and main grid line same side are on same straight line, the thin portion of L type interconnecting strip and the welding of main grid line, wide corresponding and back electrode welding.
Battery sheet with the supporting a kind of special back electrode of T type interconnecting strip, have battery sheet front that contains the main grid line and the cell back face that contains back electrode, back electrode is with respect to main grid line left-right symmetric, or back electrode is with respect to main grid line left-right symmetric and itself and back electrode one side and main grid line same side position between on same the straight line, the thin portion of T type interconnecting strip and the welding of main grid line, wide corresponding and back electrode welding.
The invention has the beneficial effects as follows, photovoltaic solar assembly of the present invention is with novel interconnecting strip and matching used battery sheet, because wide of interconnecting strip has increased area, reduce the series resistance between the battery sheet, reduced the line loss of electric current on the interconnecting strip welding, the power output that increases assembly is more than 0.5%.
