Fig. 2 is the structural representation of battery component in Fig. 1;
Fig. 3 is the plan structure schematic diagram of Fig. 2;
Fig. 4 is the plan structure schematic diagram of Fig. 1.
Embodiment
Below in conjunction with embodiment, the utility model is further described, but protection range of the present utility model is not only confined to embodiment.
As shown in Figure 1 and Figure 2, a kind of photovoltaic module taking into account synergy and welding effect, comprises the battery component be cascaded, two pieces of cell pieces 2 that each battery component comprises welding 1 and is welded on welding 1.Cell piece 2 is welded on the both sides of welding 1 respectively, represent in fig. 1 and 2 be welded on welding 1 respectively downside and upper side on.Two pieces of cell pieces 2 shift to install and on the length direction along welding 1, have spacing each other, and namely have spacing between left and right in Fig. 2, the length direction of welding 1 also refers to left and right directions.Shown in composition graphs 3 and Fig. 4, from the in-plane perpendicular to battery component, battery component defines welding 1 reverberation micro-structure region 11 upwards and cell piece 2 gray area 21 upwards, and on whole photovoltaic module, reverberation micro-structure region 11 and gray area 21 are alternately distributed.In corresponding diagram 1, reverberation micro-structure region 11 refers to the region of welding 1 under upper, cell piece 2 are welded on, also the front of battery is equivalent in use, and the surface of welding 1 in described reverberation micro-structure region 11 is irregular structure, the irregular shape of such as tool, be conducive to reflected sunlight like this, can photoelectric conversion efficiency be improved; Gray area 21 refer to welding 1 in Fig. 1 under, the region that is welded on of cell piece 2, be equivalent to the reverse side of battery in use, and the surface of welding 1 in described gray area 21 is smooth plane, flat surface can be determined to weld between welding 1 with cell piece 2 well.
Connected by cell piece 2 between battery component, each Battery pack component string be linked togather, the welding 1 between battery component has spacing, is unconnected between welding 1 and welding 1.
Reverberation micro-structure region 11 can be identical or different with the length of gray area 21, preferably identical.And the twice of reverberation micro-structure region 11 length, equals the sum that two pieces of cell piece 2 total lengths add spacing between two pieces of cell pieces 2.And in same battery component, spacing between two pieces of cell pieces 2 is 2% ~ 5% of cell piece 2 length, therefore the spacing between cell piece 2 is very little, so reverberation micro-structure region 11 is also roughly identical with the length of cell piece 2 with the length of gray area 21.
Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model, therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
