Abstract
The utility model discloses a kind of low shading rate solar battery sheet, described low shading rate 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 array of negative pole, the thin grid line array of described negative pole comprises multiple grid lines unit, and described grid line unit comprises a tie point and along tie point to the thin grid line of extraradial negative pole; The described back side is provided with negative pole main grid line; In described monocrystalline silicon piece, be provided with multiple connecting holes, described tie point 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 rate that main grid line width also can reduce solar battery sheet front.
Description
Technical field
The utility model relates to a kind of low shading rate solar battery sheet.
Background technology
As everyone knows, in the low shading rate solar cell blade technolgy of routine, 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 low shading rate 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 low shading rate 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 low shading rate solar battery sheet, described low shading rate 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 array of negative pole, the thin grid line array of described negative pole comprises multiple grid lines unit, and described grid line unit comprises a tie point and along tie point to the thin grid line of extraradial negative pole; The described back side is provided with negative pole main grid line; In described monocrystalline silicon piece, be provided with multiple connecting holes, described tie point 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 rate 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 tie point 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.Such design can be avoided short circuit.
As preferably, described monocrystalline silicon piece is horizontally disposed with, and described tie point is put direction projection and fallen into negative pole main grid line along perpendicular, and described connecting hole vertically arranges.Such design is convenient to tie point and is connected with negative pole main grid line.
As preferably, described tie point is circular.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 secondary front grid line and the back side, so both can expand main grid line width and also can reduce the shading rate in solar battery sheet front.
