Description
Technical field
The utility model relates to a kind of bending 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 thin grid line solar battery sheet of bending of shading-area of front is provided.
For achieving the above object, the technical solution of the utility model has been to provide the thin grid line solar battery sheet of a kind of bending, the thin grid line solar battery sheet of described bending comprises square monocrystalline silicon piece, described monocrystalline silicon piece comprises front and back, described front is provided with many thin grid lines of bending negative pole, the thin grid line of described negative pole is uniform to another side on one side along monocrystalline silicon piece, between the thin grid line of negative pole, is provided with connecting line; The described back side is provided with negative pole main grid line; In described monocrystalline silicon piece, be provided with multiple connecting holes, described connecting line 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, are provided with insulation film, between described negative pole main grid line and the monocrystalline silicon piece back side, are provided with insulation film.Such design prevents short circuit.
As preferably, described monocrystalline silicon piece is horizontally disposed with, and described connecting line 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 convenient to connecting line and is connected with negative pole main grid line.
As preferably, described connecting line and connecting hole junction are provided with circular tie point, and described negative pole main grid line is flexure type; The thin grid line of described negative pole is provided with Duo Tiao branch.Being designed with like this helps improve the thin grid line enrichment of negative pole electric charge ability.
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.
