Description

A kind of photovoltaic module manufacturing process
Technical field
The invention belongs to solar module technical field, relate to a kind of photovoltaic module manufacturing process.
Background technology
Tradition solar components technology comprises the preparation of solar battery sheet, single weldering is carried out to cell piece, to singly weld cell piece marshalling carries out series welding, then splicing lamination is carried out, lamination completes laggard laminating machine and carries out lamination, carry out EL detection again, detect the component process that complete installation aluminium frame completes solar panel.
At present when producing photovoltaic module, the cell piece adopted is generally light blue or blue, and the secondary grid line edge conjunction of cell piece, form frame.Single weldering and series welding need to use welding, welding is common is argenteous tin-coated copper strip, its Problems existing is: because the color of frame and welding is not black, cell piece is light blue or blue simultaneously, its photovoltaic cell component endothermic effect is not good especially, thus causes cell piece to utilize the efficiency of also conversion solar not high.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of can produce black or close to black photovoltaic module thus improve the photovoltaic module manufacturing process of solar energy utilization ratio.
Object of the present invention realizes by following technical proposal: a kind of photovoltaic module manufacturing process, is characterized in that, comprise the following steps:
S1, preparation black or navy blue cell piece;
S2, use black or Dark grey welding carry out single weldering on cell piece main grid, and carry out series welding by after the cell piece marshalling singly welded;
S3, cell piece good for series welding is carried out lamination, make solar photovoltaic assembly.
In above-mentioned a kind of photovoltaic module manufacturing process, the secondary grid line of the cell piece in described step S1 does not connect, to guarantee that the secondary grid line of cell piece can not form frame.
In above-mentioned a kind of photovoltaic module manufacturing process, the black in described step S2 or Dark grey welding are tin-coated copper strip, and described tin-coated copper strip contains tin coating, and described tin coating is black or Dark grey Sn-containing alloy.
In above-mentioned a kind of photovoltaic module manufacturing process, the black in described step S2 or Dark grey welding are tin-coated copper strip and are pasted with black or Dark grey adhesive tape on the surface at tin-coated copper strip.
Compared with prior art, this photovoltaic module manufacturing process has following several advantage:
1, the secondary grid line of cell piece does not connect, the secondary grid line of its cell piece can not form frame, other colors such as white can not be there are in cell piece cohesive position, without the frame that can not absorb sunlight generation electric energy, the space accounting of its cell piece on whole photovoltaic module is larger, thus makes capacity efficiency in photovoltaic module unit are higher;
2, cell piece is black or navy blue, because dark optical absorption is good, improves the light energy conversion effect of overall photovoltaic module;
3, the welding welding cell piece main gate line is black or Dark grey, other colors such as white can not be there are in its welding of battery film position, because dark optical absorption is good, improve the light energy conversion effect of overall photovoltaic module, whole photovoltaic module is allowed to present black or the color close to black in conjunction with above-mentioned two structures, very attractive in appearance and conversion of solar energy is high.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention.
Embodiment
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
As shown in Figure 1, this photovoltaic module manufacturing process, comprises the following steps:
S1, preparation black cell piece;
S2, use black welding carry out single weldering, and carry out series welding by after the cell piece marshalling singly welded on cell piece main grid;
S3, cell piece good for series welding is carried out lamination, make solar photovoltaic assembly.
Further, the secondary grid line of the cell piece in step S1 does not connect, to guarantee that the secondary grid line of cell piece can not form frame.The secondary grid line of cell piece does not connect, the secondary grid line of its cell piece can not form frame, other colors such as white can not be there are in cell piece cohesive position, without the frame that can not absorb sunlight generation electric energy, the space accounting of its cell piece on whole photovoltaic module is larger, thus makes capacity efficiency in photovoltaic module unit are higher.
Further, the black welding in step S2 is tin-coated copper strip, and tin-coated copper strip contains tin coating, and tin coating is black Sn-containing alloy.The welding of welding cell piece main gate line is black, and its welding of battery film position can not exist other colors such as white, due to black light good absorbing effect, improves the light energy conversion effect of overall photovoltaic module.Welding in the present embodiment step S2 can also be the tin-coated copper strip of Dark grey, and tin-coated copper strip contains the tin coating of Dark grey Sn-containing alloy.Its black welding can also be tin-coated copper strip and be pasted with black belt on the surface at tin-coated copper strip.Welding in the present embodiment step S2 also can be Dark grey welding, and Dark grey welding is tin-coated copper strip and is pasted with Dark grey adhesive tape on the surface at tin-coated copper strip.
The color of the cell piece in the present embodiment step S1 can also be the dark colours such as navy blue.Cell piece is black or navy blue, because dark optical absorption is good, improves the light energy conversion effect of overall photovoltaic module.
Whole photovoltaic module in the present embodiment presents black color, very attractive in appearance and conversion of solar energy is high.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
