Fig. 2 is the profile of second kind of execution mode of double-sided solar battery assembly of the present invention;
Wherein, 1, toughened glass, the 21, the one EVA layer, the 22, the 2nd EVA layer, the 23, the 3rd EVA layer, the 24, the 4th EVA layer, 3, the upper strata solar battery sheet, 4, the intermediate layer, 41, vee-cut, 5, lower floor's solar battery sheet, 6, transparent underlayer.
Embodiment:
For further understanding the technical characterictic and the content of patent of the present invention, combine accompanying drawing that the detailed technology of this patent is described below at present:
As shown in Figure 1; A kind of double-sided solar battery assembly comprises low iron toughened glass 1 of ultrawhite and transparent underlayer 6, is provided with four layers of EVA layer between said toughened glass 1 and the transparent underlayer 6; Wherein, Being provided with between the one EVA layer 21 and the 2nd EVA layer 22 between series welding upper strata solar battery sheet 3, the three EVA layers 23 and the 4th EVA layer 24 together and being provided with series welding lower floor's solar battery sheet 5 together, is intermediate layer 4 between said the 2nd EVA layer 22 and the 3rd EVA layer 23.
The toughened glass 1 of its mesexine has high transmission rate and plays the effect of protection solar battery sheet; The EVA material has the effect of sealing and bonding; Intermediate layer 4 has isolation and the insulation effect of two-layer solar battery sheet up and down; Bottom adopts the material of high transmission rate, like toughened glass, transparent TPT, PET etc.Wherein the TPT material also has ageing-resistant, corrosion-resistant, as to stop water vapor permeable ability and good insulation performance performance except having the function of printing opacity.
The upper strata battery sheet of described double-sided solar battery assembly all adopts the connected mode of connecting with lower floor battery sheet, and the last output of this two-layer battery sheet is separate; Upper strata battery sheet and lower floor's battery sheet can adopt identical or different arrangement mode.
Described intermediate layer is generally opaque material; It has very big reflectivity to incident light in two surfaces up and down; The incident light that wherein upper surface can reflecting & transmitting glass, this part reverberation are absorbed by upper strata battery sheet again, thereby increase the power output of upper strata battery sheet; The lower surface in intermediate layer is the incident light of reflecting & transmitting bottom then, and this part reverberation is absorbed by lower floor's battery sheet more then, has equally also increased the power output of lower floor's battery sheet.
Material transparent also can be adopted in described intermediate layer, makes the double-sided solar battery assembly also have the function of printing opacity simultaneously, is similar to a kind of transparent solar cell assembly.
As first kind of execution mode, the shape on the upper and lower surface in said intermediate layer 4 is preferably the plane.
Fig. 2 is another embodiment of the present invention, and different with first kind of execution mode is: the upper and lower surface in intermediate layer 4 be shaped as regularly arranged V-groove, this structure has very high reflectivity with respect to first kind of execution mode.When solar irradiation was mapped on this double-sided solar battery assembly, its tow sides all can absorb sunlight.For the upper strata solar battery sheet; See through the light of toughened glass except normal absorption; Absorb the secondary reflection light of a part from lower glass surface in addition, because the intermediate layer upper surface has high reflectance and is provided with V-groove, the interior angle of said vee-cut (41) is 120 degree～138 degree.The refractive index of toughened glass is about 1.5; When light when glass (optically denser medium) enters into air (optically thinner medium); Critical angle is 42 degree; V-groove makes angle when this surperficial reverberation incides the toughened glass lower surface once more greater than critical angle, absorbed by the upper strata solar battery sheet thereby total reflection takes place, so upper strata solar battery sheet power output increases.For lower floor's solar battery sheet, same phenomenon is also arranged, bigger power output is promptly also arranged.Than the single face solar module of same area, can see significantly that the double-sided solar battery assembly has higher power output, promptly the output of latter's unit are is higher.
The solar module that is 1580mm * 808mm with a specification is an example; Conventional single face assembly power output is 180W; The average power of the double-sided solar battery assembly of same specification then can reach about 250W; The energy output that is to say the one of which sky is 1.4 times of single face assembly, this shows, the energy output of double-sided solar battery assembly unit are has significant increase.
The manufacture method of double-sided solar battery assembly, making step is following:
(1) the positive welding of battery sheet: the welding that will soak scaling powder is welded on the positive main grid line of battery sheet, and the temperature of welding is at 300～360 degree;
(2) cell back face series welding: be serially connected according to the battery sheet arrangement mode of assembly battery sheet with some;
(3) lay: the order of laying is from top to bottom successively: ultrawhite is hanged down iron toughened glass, an EVA layer, upper strata solar battery sheet, the 2nd EVA layer, intermediate layer, the 3rd EVA layer, lower floor's solar battery sheet, the 4th EVA layer, transparent underlayer;
(4) lamination: the assembly that will lay is put into laminating machine, and assembly each several part material is bonded together into as a whole laminate under the vacuum high-temperature condition, then it is carried out deburring and handles;
(5) frame up: the component layer casting die is installed aluminum alloy frame, and the part that laminate contacts with frame is used silica gel sealing, and the installation connection box at the assembly back side cleans it at last then;
(6) test: the assembly that under standard test condition, the cleaning that frames up is finished carries out final electric performance test, confirms each item unit for electrical property parameters of assembly.
When in the system of reality, using this double-sided solar battery assembly; Although the up and down two-layer battery sheet of assembly all can absorbing light and produce power output; But because the solar irradiation intensity of two-layer battery sheet is different up and down; Then their output parameter such as peak power output voltage, peak power output electric current etc. also can be variant; Therefore in system design, the output of the upper strata solar battery sheet of all component is connected, lower floor's solar battery sheet output of all component carries out other connection, utilizes the DC/DC transducer that the upper strata solar battery sheet is equated with the output end voltage of lower floor solar battery sheet; Be connected in parallel at last, will reduce the power loss that mismatch is brought like this.
Technology of the present invention is simple; Realized the function that the solar module tow sides all can generate electricity; Indirect increase the assembly gross output; The energy output that is the unit are assembly has increased, and therefore uses this double-sided solar battery assembly for the limited place of those installing spaces, will obtain than the bigger income of conventional single face solar module.
