Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The present embodiment provides a kind of novel photovoltaic module, and it comprises the laminated construction that is followed successively by from top to bottom toughened glass, EVA glued membrane, multiple row solar cell string, EVA glued membrane and backboard.
The material of backboard is preferably toughened glass, like this photovoltaic module printing opacity and be conducive to improve the generating efficiency of photovoltaic module the installation that can omit frame because the back side is subject to light.
As Figure 1-3, the solar cell string is welded by welding 2 by a plurality of N-type solar battery sheets 11 and a plurality of P type solar battery sheet 12, and N-type solar battery sheet 11 and the 12 interval discharges of P type solar battery sheet.
The present embodiment also provides a kind of manufacture method of novel photovoltaic module, and the method mainly comprises the steps:
Step 1: the N-type solar battery sheet 11 of a plurality of intervals discharge and 12 use welding 2 welding of P type solar battery sheet are obtained to the solar cell string.
As shown in Figure 1, a plurality of N-type solar battery sheets 11 and a plurality of P type solar battery sheet 12 spaces are arranged into to row, and adjacent N-type solar battery sheet and P type solar battery sheet between gap be preferably 0.1mm-2mm.
Utilize welding 2 to adopt the connected mode of both positive and negative polarity to be connected two adjacent cell pieces (N-type solar battery sheet 11 and P type solar battery sheet 12),, welding 2 is welded on the electrode 3 of cell piece, the positive pole of N-type solar battery sheet 11 is connected with the negative pole of P type solar battery sheet 12, or the negative pole of N-type solar battery sheet 11 is connected with the positive pole of P type solar battery sheet 12.Because the electrode of the sensitive surface of N-type solar cell 11 and P type solar cell 12 is just in time contrary, therefore and can direct-connectedly not need to carry out the curved design of S in welding 2 connection procedures, Gu arrange can be tightr for cell piece.
As shown in Figure 2, as shown in Figure 3, wherein, the face bonding of the cell piece at solar cell string two ends is connected to welding lead end 21 at the back side in the front of the solar cell string that the cell piece discharged in Fig. 1 is obtained by welding 2 welding.
Step 2: by the solar cell string auto arrangement in multiple row step 1 good (arrangement mode as shown in Figure 4), by convergent belt 4, multiple row solar cell series winding is connected together afterwards with laying machine;
Particularly, the welding lead end 21 of multiple row solar cell string connects by one or more convergent belt 4, and as shown in Figure 5, the back side as shown in Figure 6 for the front after multiple row solar cell series winding connects.
Step 3: toughened glass, EVA glued membrane, the described solar cell string of multiple row, EVA glued membrane and the backboard that connect are arranged in order from top to bottom, for lamination is prepared;
Step 4: lamination, the toughened glass that is arranged in order up and down in step 3, EVA glued membrane, the described battery strings of multiple row, the backboard that connect are vacuumized successively, heated and pressurizeed, it is sticked together.
When the material of backboard is not selected toughened glass, also comprise step 5: frame up, by the assembly frame for installing obtained after lamination in step 4.
Due to this body structure of toughened glass, its corner part only need be subject to very little shock and will break, and the rim frame is the corner of the toughened glass in order to protect the photovoltaic module the superiors.The assembling process of frame is mainly to frame injection viscose, the framework of frame is combined, carried out some finishing process, afterwards the frame after finishing is arranged on the photovoltaic module obtained through step 4, load onto terminal box, finally adopt silica gel that it is solidified and gets final product.
To sum up, the present invention is by discharging N-type solar battery sheet and P type solar battery sheet interval, because the electrode of the sensitive surface of P type solar battery sheet and N-type solar battery sheet is just in time contrary, therefore can use direct-connected two the adjacent cell pieces of welding in the cascade process of cell piece, and do not need to carry out the curved design of S of welding, reduce the gap of two adjacent cell pieces, thereby effectively increased the generated output in unit are, the use that can also save welding and frame.
The foregoing is only preferred embodiment of the present invention, not be used for limiting practical range of the present invention; If do not break away from the spirit and scope of the present invention, the present invention is modified or is equal to replacement, all should be encompassed in the middle of the protection range of the claims in the present invention.
