Abstract
The utility model discloses a metal support plate, comprising a metal support plate plate body, wherein on the plate body there are uniformly provided silicon wafer support squared holes, a group of parallel opposite surfaces inside the silicon wafer support squared holes are symmetrically provided metal hooks, another group of parallel opposite surfaces inside the silicon wafer support squared holes are symmetrically provided positioning hooks, and both sides of the bottom surface of the metal support plate are provided with metal slideway strips. The distance between the top of the metal hooks and the lower surface of the prior metal support plate is shortened, and the thickness of the prior metal hooks is reduced. The metal support plate enables the distance between the upper surface of the silicon wafer and the lower surface of the metal support plate to be shortened, the problem of the back side edge film formation of the silicon wafer to be alleviated, and the electrical parameter and conversion efficiency of the solar battery to be improved; and simultaneously, the thickness of the metal hooks is thinned, thereby reducing the area of process points, improving the appearance of the solar battery board, and increasing the product quality.
Description
Technical field
The utility model relates to manufacture of solar cells, relates in particular to a kind of metal support plate.
Background technology
Manufacture of solar cells technology generally comprises cleaning and texturing, diffusion, etching, dephosphorization silex glass, plated film, prints electrode, sintering and testing, sorting operation; Wherein in filming process; Be contained on the metal support plate during silicon chip, be placed on again and carry out plated film processing on the filming equipment; Silicon chip lies in before processing in the metal support plate, and the metal support plate carries position, silicon chip both sides of the edge through four metal hangers, and locate silicon chip with the straight hook of metal both sides in addition.Existing metal support plate lower surface is higher than metal hanger end 5mm; Metal hanger thickness is 1mm; Therefore the silicon chip upper surface has certain distance to metal support plate lower surface; Cause in the process of process cavity plasma deposition, can forming the very thin film of one deck, have a strong impact on the electrical quantity of back solar cell in the silicon chip dorsal edge; And the inherent shortcoming of four process point (not having film forming) can appear at four metal hanger places behind the silicon chip back side coating film.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of can promote solar cell electrical quantity and transformation efficiency, reduces the process point area, improves the solar cell outward appearance, the metal support plate that improves the quality of products.
Technical scheme: for solving the problems of the technologies described above, the technical scheme of the utility model sampling is:
A kind of metal support plate; Comprise metal loading plate plate body; On plate body, be distributed with silicon chip equably and carry square hole; Be provided with metal hanger symmetrically on one group of parallel opposite face in silicon chip carries square hole, on the parallel opposite face of another group of silicon chip carrying square hole, be provided with location hook symmetrically, be provided with the metal runners bar in both sides, metal loading plate bottom surface; Reduce the distance that existing metal loading plate lower surface is higher than the hook top of metal hanger; Reduce the thickness of existing metal hanger; Consider processing technology and processing cost; Preferential metal loading plate lower surface is higher than the hook top 2-2.5mm of metal hanger, and the thickness of metal hanger is 0.4-0.5mm.
Beneficial effect: the metal support plate that the utility model provides, shortened the distance of silicon chip upper surface to metal loading plate lower surface, slowed down the problem of silicon chip dorsal edge film forming, the electrical quantity of solar cell and transformation efficiency are improved; Simultaneously,, directly reduced the area of process point, improved the outward appearance of solar panel, improved product quality because the thickness of metal hanger obtains attenuate.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Be depicted as a kind of metal support plate like accompanying drawing 1; Comprise metal loading plate plate body 1; On plate body 1, be distributed with silicon chip equably and carry square hole 2; Be provided with metal hanger 3 symmetrically on one group of parallel opposite face in silicon chip carries square hole, on the parallel opposite face of another group of silicon chip carrying square hole, be provided with location hook 4 symmetrically, be provided with the metal runners bar in both sides, metal loading plate bottom surface; Said metal loading plate lower surface is higher than the hook top 2-2.5mm of metal hanger 3, and the thickness of metal hanger 3 is 0.4-0.5mm.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
