Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2, solar power generation assembly comprises the backboard 1 at the back side and the glass plate 2 in front, and multi-disc solar battery sheet 3 is pressed together in the middle of backboard 1 and glass plate 2 by front adhesive film 4 and back side adhesive film 5; Front adhesive film 4 is positioned between glass plate 2 and solar battery sheet 3, and back side adhesive film 5 is positioned between backboard 1 and solar battery sheet 3; For preventing each solar battery sheet 3 from contacting with each other, between each solar battery sheet 3, there is gap 6.
Solar power generation assembly configures in the solar battery sheet 3, Fig. 1 of suitable quantity according to required generated output, for clarity sake, has only drawn 4 pieces of solar battery sheets 3, in reality, may have tens solar battery sheets 3 according to the mode arrayed in Fig. 1.The material of front adhesive film 4 and back side adhesive film 5 can adopt EVA(ethylene-vinyl acetate copolymer) glued membrane, it has higher light transmission, stability and insulating properties.
In order to multi-disc solar battery sheet 3 mode as required be coupled together (serial or parallel connection), be laid with grid line 8 on the surface of solar battery sheet 3.In the side structure of Fig. 2, omit and do not draw grid line 8, it should be noted that, grid line 8 is positioned at solar battery sheet 8 surface, under front adhesive film 4.The end of grid line 8 is connected with welding 9, and welding 9 can be tin-coated welding strip, is distributed in the side of solar battery sheet 3, does not contact with solar battery sheet 3.In actual fabrication, after welding 9 is connected with grid line 8, then be crushed in the middle of front adhesive film 4 and back side adhesive film 5.
The surrounding of solar power generation assembly usually also wraps and is provided with a circle frame 10, and frame 10 plays the effect of protection solar power generation assembly side.
As can see from Figure 1, the gap 6 between solar battery sheet, and the vacant position 11 around solar battery sheet has been wasted usable floor area, these areas can not absorb solar power generation, thus affect the generating efficiency of whole solar power generation assembly.
For this reason, the gap 6 between solar battery sheet and the vacant position 11 around solar battery sheet reflective membrane can be covered; This reflective membrane front has concaveconvex structure and can laterally reflect or refracted ray, and so sunlight can be reflected, be distributed to contiguous solar battery sheet 3 surface, the lifting obtaining light efficiency with this brings the raising of generating efficiency simultaneously.See in vertical structure, reflective membrane is overleaf on adhesive film 5, under front adhesive film 4.
The concrete structure of reflective membrane as shown in Figure 3, comprise film matrix 101, the back side of film matrix 101 is adhesive faces 102, and front has the concaveconvex structure 103 with film matrix 101 one, the surface coverage of concaveconvex structure 103 has one deck reflecting coating 104, and reflecting coating 104 surface forms reflective surface 105.Film matrix 101 can adopt polycarbonate plastic, resinae plastic or other material; The material of reflecting coating 104 can select the metals such as silver, aluminium, zinc.The thickness of film matrix 101 is 0.01mm ~ 0.5mm.
Concaveconvex structure 103 comprises the depressed part 1032 between multiple continuous print isosceles triangular hill 1031 and projection; The height of isosceles triangular hill 1031 is about the 5%-50% of film matrix 101 thickness.This kind of structure can cause the repeatedly correlation of light, refraction and reflection, and sunlight is being irradiated to after on reflective membrane, and the solar battery sheet 3 having major part can be close to by horizontal directive, forms strong Light Source Compensation.The corner angle of isosceles triangular hill 1031 is preferably 30-70 degree.
After frame 10 wrapped by solar power generation assembly, can also also cover above-mentioned reflective membrane at the upper surface of frame 10, form stronger Light Source Compensation further.
