Abstract
The invention discloses a pentagonal photovoltaic cell whose edges are fillets. The pentagonal photovoltaic cell is characterized in that a cell piece provided by the invention is in the shape of a regular pentagon, and edges of one side of the regular pentagonal cell piece are ground into arc edges. The apex angles of the cell piece are ground into arc angles. The thickness of the cell piece is 1.5mm to 2mm. The radii of the arc edges and the arc angles are the same as that of the cell piece. According to the pentagonal photovoltaic cell provided by the invention, the periphery of crystal silicon on the cell piece is ground into round corners, and the radii of the round corners are consistent with the thickness of the cell piece. The stress concentration of a crystal silicon cell is reduced, the strength and the superficial area of the crystal silicon cell are increased, the power generation efficiency is improved, and the rejection rate is reduced.
Description
Technical field
The present invention relates to photovoltaic industry field, particularly a kind of pentagon edge is fillet photovoltaic cell.
Background technology
At present, cell production companies, in order to reduce costs, subtracts the thickness of book crystal silicon battery one after another.But crystal-silicon battery slice is fragile material, there is problem of stress concentration in the silicon chip edge position after section, easily causes fragment problems.Therefore, the rate of finished products of silicon chip will be affected after reducing thickness.
Summary of the invention
For the problems referred to above, the present invention is intended to a kind of arc chord angle structure eliminating edge stress, and for achieving the above object, providing a kind of pentagon edge is fillet photovoltaic cell.
Technical solution of the present invention is such:
A kind of pentagon edge is fillet photovoltaic cell, it is characterized in that: cell piece of the present invention is regular pentagon, the edge of described regular pentagon cell piece one side is ground to arc-shaped edges, the drift angle of cell piece is ground to arc chord angle, cell piece thickness is 1.5 ~ 2.2mm, and the radius of arc edge arc chord angle is identical with the thickness of cell piece.
Advantage of the present invention:
The periphery of crystal silicon is established by this cell piece and is ground to fillet, the radius of this fillet and the consistency of thickness of cell piece.Thus the stress decreasing crystal silicon battery is concentrated, add intensity and the surface area of crystal silicon battery, improve generating efficiency, reduce percent defective.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further explained.
A kind of pentagon edge is fillet photovoltaic cell, it is characterized in that: cell piece 1 of the present invention is regular pentagon, and the edge of described regular pentagon cell piece one side is ground to arc-shaped edges 3.
Further preferred version is, the drift angle of described cell piece is ground to arc chord angle 2, and cell piece thickness is 1.5 ~ 2.2mm.
Further preferred version is, the radius of described arc edge arc chord angle is identical with the thickness of cell piece.
Foregoing, is only preferred embodiment of the present invention, and not for limiting embodiment of the present invention, those skilled in the art are according to design of the present invention, and done appropriate adaptation or amendment, all should within protection scope of the present invention.
