Abstract
The utility model discloses a novel graphite boat. The graphite boat comprises a graphite boat substrate, a cylindrical fixing column is arranged at the bottom of the graphite boat substrate, and star-shaped clamp points are arranged at two sides of the graphite boat substrate respectively. The cylindrical fixing column is used to hold a cell panel from below to prevent the cell panel from slip downwards. The two star-shaped clamp points are used to clamp the cell panel from the two sides, and the star-shaped clamp points are corresponding to main grid lines of the cell panel. The design of the graphite boat can decrease the influence of the clamp points on the cell panel from three points in the prior art to two points, so that materials and costs are reduced. And by arranging the star-shaped clamp points in correspondence to the main grid lines, dead zones of the cell panel are fully utilized, the shielded area of the cell panel is decreased, and the solar energy conversion efficiency is improved.
Description
Technical field
The utility model relates to a kind of solar cell tool, particularly a kind of Novel graphite boat.
Background technology
At present, it is the circular stuck point of graphite boat that existing solar battery sheet is produced in the middle of PECVD what use, for blocking the silicon chip in the middle of the graphite boat sheet, in order to better energising is arranged when carrying out exoelectrical reaction, make silicon nitride be deposited on the surface of silicon chip, form the thick silicon nitride film of 80-85AM.But the part that silicon chip contacts with stuck point, owing to by stuck point, being blocked and not forming silicon nitride film, causes final battery edge that certain flaw is arranged.How making shield portions reduce, or eliminate the impact of shield portions on cell piece, is urgent problem.
Summary of the invention
Goal of the invention: the purpose of this utility model is to solve the high cost that prior art graphite boat stuck point number too much causes, and the stuck point position arranges the improper problem that causes the cell panel edge to block caused.
Technical scheme: the utility model provides following technical scheme: a kind of Novel graphite boat, comprise the graphite boat substrate, and the graphite boat base plate bottom arranges cylindrical fixed leg, and graphite boat substrate both sides arrange respectively star-like stuck point.
As optimization, the thickness of described cylindrical fixed leg is 2.5mm, and diameter is 9mm.
As optimization, the circle at described star stuck point place is to take the circle that 8mm is radius.Beneficial effect: the utility model compared with prior art: cylindrical fixed leg for from below, holding cell panel, prevents from gliding, and the star-like stuck point of both sides is for blocking the cell panel both sides, and star-like stuck point is corresponding to the main grid line on cell panel.Design of the present utility model can make stuck point just by three original points, be kept to two points to the impact of cell piece, materials have been reduced, save cost and passed through the corresponding main grid line of star-like stuck point, can take full advantage of the dead band of cell panel, reduce the shielded area of cell piece, improved the solar energy conversion efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of Novel graphite boat, comprise graphite boat substrate 1 as shown in Figure 1, and graphite boat substrate 1 bottom arranges cylindrical fixed leg 2, and graphite boat substrate 1 both sides arrange respectively star-like stuck point 3.The thickness of described cylindrical fixed leg 2 is 2.5mm, and diameter is 9mm.The circle at described star stuck point 3 places is to take the circle that 8mm is radius.
Cylindrical fixed leg of the present utility model, for from below, holding cell panel, prevents from gliding, and the star-like stuck point of both sides is for blocking the cell panel both sides, and star-like stuck point is corresponding to the main grid line on cell panel.Design of the present utility model can make stuck point just by three original points, be kept to two points to the impact of cell piece, materials have been reduced, save cost and passed through the corresponding main grid line of star-like stuck point, can take full advantage of the dead band of cell panel, reduce the shielded area of cell piece, improved the solar energy conversion efficiency.
