Embodiment
Collection as shown in Figure 2 has the solar module of fluorescent flat optical waveguide structure to use backboard, has concavo-convex backboard body 4, can hold battery sheet 1 in the groove 4-1 of backboard body 4, and the protruding 4-2 of backboard body 4 is provided with fluorescent flat optical waveguide 5.The design of backboard body 4 is that the conventional backboard is made that through certain calendering technology or other technologies the volume of the volume of sunk area and battery sheet 1 is suitable corresponding to the position local dent of battery sheet 1 placement, and the degree of depth is about 180～200 μ m.The purpose that backboard body 4 is made concavo-convex structure is to make the flush of lower surface and battery sheet 1 of fluorescent flat optical waveguide 5 to make the fluorescence 11 that penetrates from fluorescent flat optical waveguide 5 narrow and small sides fully to be utilized.
This backboard is applied on the solar module, and solar module has the solar panel that is formed by solar battery sheet connection in series-parallel encapsulation, and the back side of solar panel is provided with this backboard.
As shown in Figure 3, fluorescent flat optical waveguide 5 is generally rectangle, and lateral area wants specific area little a lot of usually all around, and fluorescent flat optical waveguide 5 comprises fluorescence conversion layer 6 and transparent dielectric layer 7.Wherein fluorescence conversion layer 6 is made up of residuite 6-1 and the fluorescence transformational substance 6-2 that is dispersed on the residuite 6-1; Fluorescence transformational substance 6-2 can be rare earth compounding, organic dyestuff or quantum dot etc.; Fluorescence transformational substance 6-2 proportion is advisable for not influencing visible light transmissive to greatest extent, and the mass percent with 5wt%～10wt% is dispersed among the residuite 6-1 usually.Fluorescence conversion layer 6 can be individual layer conversion film structure, multi-layer compound structure, ribbon structure or lattice structure etc.; The thickness of fluorescence conversion layer 6 is 5～20 μ m; Fluorescence transformational substance 6-2 can absorb the sunlight 10 in certain wave-length coverage, and has emission peak at the best corresponding wave band of conventional solar cell; Transparent dielectric layer 7 can have the transparency of identical performance for glass, polymethyl methacrylate or other; The thickness of transparent dielectric layer 7 is about 0.2～1.5mm, and the shape and size of transparent dielectric layer 7 decide by the shape of the assembly void area 3 that fluorescent flat optical waveguide 5 is put.
With fluorescence conversion layer 6 is that individual layer conversion film structure is an example, and the preparation process that is integrated with the fluorescent flat optical waveguide fabric backplanes is following:
One, at first selects the fluorescence transformational substance 6-2 of 5wt%～10wt% proportion,, be dispersed among the residuite 6-1 among certain density PMMA or the EVA, form fluorescence conversion layer 6, the about 10 μ m of the thickness of fluorescence conversion layer like rhodamine 6G; Utilize methods such as spin coating or printing with fluorescence conversion layer 6 be coated on definite shape, thickness is transparent dielectric layers such as glass or PE 7 tops for 0.2mm, material.As shown in Figure 3; For guaranteeing to escape from transparent dielectric layer 7 upper and lower surfaces through the fluorescence 11 that fluorescence conversion layer 6 obtains; Then selective reflecting layer 8 is set at transparent dielectric layer 7 upper surfaces; Promptly select to have the material of specific refractive index, reflective coating film 9 is set, as any one of light reflecting effect material arranged by Ag, Al, organic-inorganic diffuse-reflective material or one dimension, two dimension, multidimensional photonic crystal etc. at transparent dielectric layer 7 lower surfaces; The exiting surface 13 of the side of transparent dielectric layer 7 must guarantee smooth, to help the refraction of fluorescence 11.
Two, again the use of the fluorescent flat optical waveguide for preparing 5 through calendering in advance or combination optical lens gelatin is integrated on the protruding 4-2 of backboard body 4, promptly corresponding to assembly void area 3.
The backboard that this kind has a fluorescent flat optical waveguide 5 uses not influence in traditional components and effectively is electrically connected and effective component package.It is fixed to come by physical location for the quantity of fluorescent flat optical waveguide 5 requirements, shape, size and required exiting surface 13.The surface configuration of fluorescent flat optical waveguide 5 can be triangle, rectangle, square or other polygons.For the quantity of exiting surface 13, a position as shown in Figure 1 all has battery sheet 1 to surround around the fluorescent flat optical waveguide 5, and then the four sides all needs outgoing fluorescence 11; B as shown in Figure 1; Positions such as c and like Fig. 4 and shown in Figure 5; Wherein have only one side, two sides or N face to have battery sheet 1 to surround; Then need reflector 12 is arranged in other sides, make sunlight 10 focus on battery sheet 1 certain several times outgoing accordingly, thereby guarantee that light is made full use of by battery sheet 1.
Operation principle: when sunlight 10 from assembly top irradiation to assembly 5 last times of fluorescent flat optical waveguide; Fluorescence transformational substance 6-2 will absorb sunlight 10 and launch the fluorescence 11 of certain wave band; Fluorescence 11 incided in the transparent dielectric layer 7 and propagated this moment, because the upper surface of transparent dielectric layer 7 is provided with selective reflecting layer 8, lower surface is provided with reflective coating film 9; When the incidence angle of fluorescence 11 drops in the angle of total reflection; Fluorescence 11 will experience a series of reflections, refraction at the lower surface of selective reflecting layer 8 and the upper surface of reflective coating film 9, finally penetrate from the side of fluorescent flat optical waveguide 5, and a part of fluorescence 7 is directly incident on battery sheet 1 surface and is utilized by battery sheet 1; Another part fluorescence 7 incides the packaged glass inner surface; The welding surface, the experience diffuse reflection of surface such as aluminium shape surface is the irradiation route that battery sheet 1 utilizes again again, improves the utilance of solar cell to the sunlight of assembly void area 3; Because fluorescent flat optical waveguide 5 is sheet-form optical structures; Its lateral area specific area is little a lot; Make it can receive the light of the similar area of fluorescent flat optical waveguide 5 upper surfaces, through the conversion of fluorescence conversion layer 6 and most reflection and the refraction in transparent dielectric layer 7, side very little around finally concentrating on is penetrated; The corresponding increase of light intensity; Be equivalent to reach the effect of bigger equivalent optically focused, the multiple that light intensity increases is proportional to surface area/lateral area ratio, thus photoelectric conversion efficiency that can 1 pair of sunlight 10 of corresponding raising battery sheet.
The method that has same effect with the present invention is that suitable fluorescent flat optical waveguide 5 is mutually integrated with the lower surface of component package glass, is used to improve solar cell equally to irradiation making full use of to the sunlight 10 of assembly void area 3.
