In some embodiments, as shown in Figure 3, uvioresistant substrate 310 has loading end 312.Reflection configuration 320, adhering layer 330 and 340 are all arranged on the loading end 312 of uvioresistant substrate 310.Furthermore, loading end 312 has middle section 314 and two neighboring areas 316 and 318.Neighboring area 316 and 318 is positioned at the relative both sides of middle section 314.In other words, middle section 314 is between neighboring area 316 and 318.Reflection configuration 320 is arranged on middle section 314.Adhering layer 330 is arranged on neighboring area 316, and adhering layer 340 is arranged on neighboring area 318.Neighboring area 316 is positioned at the first solar cell 100 (can consult Fig. 2) below, sticks together the first shady face 104 of the first solar cell 100 in order to adhering layer 330.Neighboring area 318 is positioned at the second solar cell 200 (can consult Fig. 2) below, sticks together the second shady face 204 of the second solar cell 200 in order to adhering layer 340.The below of the clearance G of middle section 314 between the first solar cell 100 and the second solar cell 200, reflexes to the first sensitive surface 102 of the first solar cell 100 and the second sensitive surface 202 of the second solar cell 200 in order to reflection configuration 320 respectively by light L1 and L2 entering clearance G.
In known solar energy module; each adhesive tape only can stick together single to solar cell; in other words; multipair solar cell is sticked together by different adhesive tape respectively; therefore when solar energy module is in lamination process; when the material of light transmission protective layer not yet solidifies, this uncured material easily flows and causes solar cell to offset, and causes the gap between solar cell inconsistent.Therefore, one of the present invention embodiment proposes following technical scheme, with head it off.Specifically, can consult Fig. 4, this figure illustrates first solar cell 100, second solar cell 200 of foundation an embodiment of the present invention and the vertical view of adhesive tape 300.As shown in Figure 4, the quantity of the first solar cell 100 is multiple, and the quantity of the second solar cell 200 is also multiple, and adhering layer 330 can stick together these the first solar cells 100, and adhering layer 340 can stick together these the second solar cells 200.In other words, the first solar cell 100 and the paired setting of the second solar cell 200, and an adhesive tape 300 can stick together multiple to the first solar cell 100 and the second solar cell 200.Thus, even if solar energy module is in lamination process, the material of printing opacity coating layer 400 (can consult Fig. 2) is uncured and flow, adhesive tape 300 also firmly can maintain the relative position of multipair first solar cell 100 and the second solar cell 200, and prevents the first solar cell 100 and the second solar cell 200 from offseting because of the flowing of the material of printing opacity coating layer 400.
In some embodiments, as shown in Figure 4, uvioresistant substrate 310 can be list structure, and has length direction D1 and width D2.Length direction D1 and width D2 is perpendicular in fact.Length direction D1 is parallel to the direction of the longest edge of uvioresistant substrate 310.The in fact alongst D1 arrangement of multiple first solar cell 100.Multiple second solar cell 200 also in fact alongst D1 arrangement.In other words, the first solar cell 100 is identical with the orientation of the second solar cell 200, and is all parallel to the longest edge of uvioresistant substrate 310.Therefore, first solar cell 100 and the second solar cell 200 can along the length direction D1 of uvioresistant substrate 310, and be attached to relative two longest edges of uvioresistant substrate 310, thus increase the quantity of the first solar cell 100 that each adhesive tape 300 can stick together and the second solar cell 200.
In some embodiments, as shown in Figure 4, the orientation of adhering layer 330,340 and reflection configuration 320 is substantially perpendicular to length direction D1's.In other words, the orientation of adhering layer 330,340 and reflection configuration 320 is parallel to width D2, that is adhering layer 330, reflection configuration 320 can sequentially arrange along width D2 with adhering layer 340.
Should be appreciated that, it " in fact " described in this specification in order to modify any can the relation of slight variations, but this slight variations can't change its essence.For example, " multiple first solar cell 100 in fact alongst D1 arrangement " is except the orientation that comprises the first solar cell 100 embodiment completely parallel with length direction D1, as long as the first solar cell 100 is positioned at the opposition side with the second solar cell 200 on adhesive tape 300, the orientation of the first solar cell 100 and the slightly not parallel embodiment of length direction D1 also can be comprised.
Please later consult Fig. 1, in some embodiments, solar energy module also can comprise adhesive tape 600.First solar cell 100 of the sticked together two-phase separation of adhesive tape 600, or the second solar cell 200 that two-phase is separated.Adhesive tape 600 and adhesive tape 300 are list structure, and the length direction of adhesive tape 600 is parallel to the width D2 of adhesive tape 300.In other words, the length direction of adhesive tape 600 and the length direction D1 of adhesive tape 300 perpendicular, and adhesive tape 300 is also perpendicular with the orientation of adhesive tape 600.That is adhesive tape 300 laterally arranges, and adhesive tape 600 longitudinally arranges.Thus, adhesive tape 300 and adhesive tape 600 firmly can stick together the first solar cell 100 and the second solar cell 200.The concrete structure of adhesive tape 600 and material as adhesive tape 300 the 2nd and 3 figure and aforementioned relevant paragraph contained, therefore not repeated description.
Although the present invention discloses as above with embodiment; so itself and be not used to limit the present invention, any those skilled in the art person, without departing from the spirit and scope of the invention; when doing various changes and retouching, the protection domain of therefore the present invention is when being as the criterion with claims.
