Description
Technical field
The utility model relates to a kind of main grid line and is arranged on the solar battery sheet at the back side.
Background technology
As everyone knows, in conventional solar cell blade technolgy, main grid line is positioned at cell piece front, in order to reduce final series resistance, therefore needs certain width, but has also increased positive shading-area simultaneously, is unfavorable for the raising of electricity conversion.Prior art is badly in need of a kind of solar battery sheet that is conducive to reduce positive shading-area.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, provides a kind of main grid line that is conducive to reduce positive shading-area to be arranged on the solar battery sheet at the back side.
For achieving the above object, the technical solution of the utility model has been to provide a kind of main grid line and has been arranged on the solar battery sheet at the back side, the solar battery sheet that described main grid line is arranged on the back side comprises square monocrystalline silicon piece, described monocrystalline silicon piece comprises front and back, there are many thin grid lines of linearity negative pole in the equal portion in described front, and an opposite side of the thin grid line of described negative pole and monocrystalline silicon piece be arranged in parallel; The described back side is provided with two linearity negative pole main grid lines, and an other opposite side of described negative pole main grid line and monocrystalline silicon piece be arranged in parallel; In described monocrystalline silicon piece, be provided with multiple connecting holes, the thin grid line of described negative pole is connected by connecting hole with negative pole main grid line; The described back side is also provided with positive electrode.So both can expand the shading-area that main grid line width also can reduce solar battery sheet front.
As preferably, in described connecting hole, be filled with conductive silver paste, described conductive silver paste two ends are connected with the thin grid line of negative pole and negative pole main grid line respectively; Between described conductive silver paste and connecting hole inwall, be provided with insulation film, between described negative pole main grid line and the monocrystalline silicon piece back side, be provided with insulation film.Avoid like this short circuit.
As preferably, described monocrystalline silicon piece is horizontally disposed with, and to put direction projection staggered along perpendicular for the thin grid line of described negative pole and negative pole main grid line.Such design is the further optimization to scheme.
As preferably, the thin grid line of described negative pole and connecting hole junction are provided with circular tie point.The thin grid line of negative pole and being connected that silver is starched are convenient in such design.
Advantage of the present utility model and beneficial effect are: in order to increase to greatest extent light-receiving area, we move on to main grid line at the back side of cell piece, by punching on cell piece, the mode that slurry is inserted in hole couples together the main grid at secondary front grid line and the back side, so both can expand main grid line width and also can reduce the shading-area in solar battery sheet front.
