Description
Technical field:
The utility model relates to solar cell, especially a kind of high euphotic solar energy battery.
Background technology:
Existing solar battery sheet comprises silver grid line of 70 to 100 transverse directions being printed on front side of silicon wafer and the silver main gate line of 2 longitudinal directions.But use silver grid line (comprising main gate line and time grid line) to expend too much noble silver, add production cost, simultaneously because the light transmission of silver is poor, blocked a part of light, decreased the power stage of cell piece.
Therefore, the utility model proposes a kind of high euphotic solar energy battery of one of improvement at this.
Utility model content:
For the defect existed in prior art, the purpose of this utility model is just to provide a kind of solar cell that can improve the light transmission of solar battery sheet.
The utility model solves the technical scheme that its technical problem adopts: a kind of high euphotic solar energy battery, the auxiliary grid line comprising cell piece body and be arranged on cell piece body and main gate line, it is characterized in that: described supplementary gate line parallel arrangement, described main gate line is perpendicular to auxiliary grid line and linked together by described auxiliary grid line, described auxiliary grid line is be printed on multiple silicon point of described cell piece body surface and the light transmitting electro-conductive line being connected each silicon point, and described light transmitting electro-conductive line is Graphene slurry.
By adopting above technical scheme, by have employed Graphene slurry light transmitting electro-conductive line light transmitting electro-conductive slurry, decreasing silver grid line blocking light, the series resistance of cell piece is declined, fill factor, curve factor rises, and improves the light transmission of cell piece.
Accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model close-up schematic view.
Figure grade illustrates: 1-cell piece body, 1-assists grid line, 3-main gate line, 4-silicon point, 5-light transmitting electro-conductive line.
