Description
Technical field
The utility model relates to a kind of square thin grid line solar battery sheet.
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 need certain width, but also increased positive shading-area, such structure is unfavorable for the raising of electricity conversion simultaneously.Prior art is badly in need of a kind of little solar battery sheet of shading-area of front.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of little square thin grid line solar battery sheet of shading-area of front is provided.
For achieving the above object, the technical solution of the utility model has been to provide a kind of square thin grid line solar battery sheet, described square thin grid line solar battery sheet comprises square monocrystalline silicon piece, described monocrystalline silicon piece comprises front and back, described front is provided with the thin grid line of square negative pole of many sealings, and it is uniform that the thin grid line of described negative pole is expanding along the mediad surrounding of monocrystalline silicon piece; The described back side is provided with the negative pole main grid line arranging along monocrystalline silicon piece diagonal angle; In described monocrystalline silicon piece, be provided with a plurality of connecting holes, the thin grid line of described negative pole is connected by connecting hole with negative pole main grid line; Described negative pole main grid line both sides are also provided with positive electrode.So both can expand main grid line width and also can reduce the shading-area in 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 negative pole main grid line with the thin grid line of negative pole 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.Such design can be avoided short circuit.
As preferably, described monocrystalline silicon piece is horizontally disposed with, and the thin grid line of described negative pole is put direction projection and negative pole main grid line is staggered along perpendicular, and described connecting hole arranges along intervening portion vertical direction.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, and described negative pole main grid line linearly.Such design is the further optimization to scheme.
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 the secondary grid line in front and the back side, so both can expand main grid line width and also can reduce the shading-area in solar battery sheet front.
