Rear side sealing 5A is close to wiring portion 3, connecting electrode 6a, the link 9 that forms charging part.Thus, the electrical insulating property of rear side sealing 5A need to have the electrical insulating property of the degree that these charging part are not short-circuited.The preferred electrical insulating property of rear side sealing 5A with the solder resist that was used as insulating protective layer in printed base plate and/or solar module in the past for more than equal.
The preferred number range of the electrical insulating property of rear side sealing 5A is 10 according to resistivity (volume intrinsic resistance value)
13more than Ω cm.
In addition, the material using in rear side sealing 5A is preferably easy softening material when heating, for example, the storage elastic modulus E while being heated to 150 ℃ ' be preferably 10
3pa～10
7pa left and right.
As the material of rear side sealing 5A, can adopt such resin material single component with electrical insulating property or in resin material, add the composite material of the additives such as pigment, filler.As the example that is suitable for the resin material of rear side sealing 5A, can list EVAc (EVA) (resistivity: 10
13Ω cm).
In addition, as the example except EVA, for example, can list ethylene methacrylic acid copolymer (EMAA) (resistivity: 10
17Ω cm), ethylene acrylic acid co polymer (EAA), ionomer (resistivity: 10
16Ω cm), for example comprise polypropylene (resistivity: 10
16Ω cm) etc. olefine kind resin, polyvinyl butyral resin (PVB), silicones (resistivity: 10
14Ω cm) etc.
The resistivity of these resin materials is all large than EVA, and can obtain better electrical insulating property, therefore as preferred material.
In addition, these resin materials do not produce the material that acetic acid etc. may corrode wiring, therefore can improve durability thereby more preferably.
In addition, for example, compare and can obtain at an easy rate with solder resist.
Herein, about resistivity, by the numerical example of the appropriate level among each resin material being recited as with reference to obtaining.
Use in the situation of composite material as rear side sealing 5A, while using pigment as additive, can rear side sealing 5A is painted thereby preferred.
Rear side sealing 5A is owing to filling according to the mode that covers wiring portion 3, thereby rear side sealing 5A carried out to when painted, when light-transmitting substrate 7 sides are watched, cannot see wiring portion 3, and it is good that the outward appearance of solar module 50 becomes.
Kind, color about the pigment that adds, if obtain the necessary resistivity of rear side sealing 5A, be not particularly limited, and can adopt suitable kind, color.
For example, as Chinese white, preferential oxidation titanium, barium sulfate.As the addition of these Chinese whites, preferably below above 20 % by weight of 0.5 % by weight.
During Chinese white less than 0.5 % by weight, have the fully possibility of buried wirring portion 3.
When Chinese white surpasses 20 % by weight, the shared quantitative change of pigment obtains too much in side seals 5A overleaf, thereby the cementability of adherend is reduced, or component costs increases.
For example,, as preferred carbon black of black pigment etc.The addition of black pigment, thus also can be by considering that disguise with respect to wiring portion 3, electrical insulating property, cementability etc. determine suitable addition.The disguise of black pigment is more excellent than Chinese white, if thereby addition be more than 0.1 % by weight, can obtain sufficient disguise so.
Particularly use carbon black to be preferably below above 10 % by weight of 0.1 % by weight as the addition in the situation of black pigment.
During carbon black less than 0.1 % by weight, have the fully possibility of buried wirring portion 3.
When carbon black surpasses 10 % by weight, thus have conduction because of carbon black make resistivity as rear side sealing 5A become too low cannot there is sufficient electrical insulating property may.
In addition, use in the situation of composite material as rear side sealing 5A, for example, in order to improve intensity or to improve resistivity, also can add the filler except pigment.
As the filler that makes an addition to rear side sealing 5A, such as listing inorganic filler such as the resin extenders such as propylene, silica possessing electrical insulating property etc.
Such filler possesses as the function that maintains the electrical insulating property of rear side sealing 5A and the separator of thickness.The not good situation that the thickness attenuation of rear side sealing 5A when thus, can prevent by lamination sealed solar energy battery unit 6 is short-circuited.
As the size of filler, below the thickness of side seals 5A, being preferably average grain diameter is 5 μ m～150 μ m overleaf.In addition, particle diameter distributes and for example by laser diffractometry, measures.
The thickness of rear side sealing 5A is preferably below the above 450 μ m of 30 μ m.In addition, within the scope of this, the words of thin thickness can reduce the consumption of link 9, thereby more preferably.
During the thickness less than 30 μ m of rear side sealing 5A, having cannot embedding wiring side 2b and the difference of height of wiring portion 3, and produces gap or make sensitive surface side seals 5B be contacted with the possibility of wiring portion 3.
When the thickness of rear side sealing 5A surpasses 450 μ m, the consumption of rear side sealing 5A, link 9 becomes too much thereby component costs becomes large.
It is upper and stacked that sensitive surface side seals 5B is close to the sensitive surface 6b of rear side sealing 5A and solar battery cell 6, and be close to light-transmitting substrate 7, and formed by the material with transmitance.
As the material of sensitive surface side seals 5B, can adopt the suitable resin material with transmitance.Particularly, can all adopt in the past the known encapsulant for sealed solar energy battery unit.
As the example that is applicable to the resin material of sensitive surface side seals 5B, can list the EVA that is in the past mostly used as the encapsulant of solar battery cell.
In addition, as the example except EVA, such as can list EMAA, EAA, ionomer, such as the olefine kind resin that comprises polypropylene etc., PVB, silicones etc.
In present embodiment, that be contacted with the charging part such as wiring portion 3 is rear side sealing 5A, and sensitive surface side seals 5B is not contacted with the charging part such as wiring portion 3.
Thus, even if use to produce the EVA of acetic acid in sensitive surface side seals 5B, by using the material that does not produce acetic acid etc. as rear side sealing 5A, also can positively prevent that corrosion because of wiring from causing deteriorated.According to such structure, can improve the durability of solar module 50.
In addition, sensitive surface side seals 5B may not need the such electrical insulating property of rear side sealing 5A, thereby can adopt resistivity than the little material of rear side sealing 5A.
Therefore, the material of the sensitive surface side seals 5B that use amount is more than rear side sealing 5A can adopt with rear side sealing 5A compares cheap material, thereby can reduce the component costs as sealing 5 integral body.
About the resin material using in sensitive surface side seals 5B, if can obtain essential transmitance, also can be identical with the resin material using in rear side sealing 5A.In the case, also can see the situation of wiring portion 3 from light-transmitting substrate 7 sides, can be also the structure of not adding pigment etc. in side seals 5A overleaf.
As the thickness of sensitive surface side seals 5B, be preferably below the above 1000 μ m of 100 μ m.
During the thickness less than 100 μ m of sensitive surface side seals 5B, intensity becomes insufficient, thereby for example in the situation that having applied external force, has the possibility that solar battery cell 6 breaks.
When the thickness of sensitive surface side seals 5B surpasses 1000 μ m, the consumption of sensitive surface side seals 5B becomes too much thereby increases component costs.
About light-transmitting substrate 7, sensitive surface 6b for solar battery cell 6 that the incident light from outside is led, because of but the plate-shaped member that formed by the material with transmitance in the scope that covers sensitive surface 6b and wiring sheet material 4, arrange, and be closely set in sensitive surface side seals 5B.
In addition, light-transmitting substrate 7 becomes the parts of the outer surface that to form with protective layer 1 side be opposition side in solar module 50.

At the thickness direction of solar module 50, protective layer 1 forms the outer surface on single composition side with light-transmitting substrate 7, thereby forms the sheet parts that suppress to invade such as moisture and/or oxygen etc. solar module 50 inside.The back side 2a of wiring sheet material 4 is close to and is incorporated into protective layer 1.
As the preferred material of protective layer 1, can list to the suitable resin material of the barrier excellence of moisture and/or oxygen, at the surperficial evaporation aluminium oxide of resin film, silica etc. and composite laminate film of the evaporated film obtaining, aluminium foil and suitable resin etc.
As the example of the structure of the resin material using in protective layer 1, such as can list by fluororesin, PET resin, fluororesin sequentially stacked the and laminate film that obtains, by hydrolysis PET resin, PET resin, the laminate film that obtains according to this sequential cascade for the prime cement layer (anchor coat layer) improving with the bonding force of sheet substrate 2 etc.
In addition, in the situation that obtain essential barrier by wiring sheet material 4, also can omit protective layer 1.
Below, an example of the manufacture method of the solar module 50 of such structure is described.Fig. 2 (a), Fig. 2 (b) are the specification figure that the manufacturing process of the wiring sheet material using in the solar module of embodiments of the present invention is described.Fig. 3 is the specification figure of manufacturing process of the solar module of explanation embodiments of the present invention.Fig. 4 is the specification figure of manufacturing process of solar module that is connected in the explanation embodiments of the present invention of Fig. 3.
In order to manufacture solar module 50, as shown in Fig. 2 (a), use conductive sheet 30 sequentially stacked protective layer 1, sheet substrate 2, wiring.Now, at interlayer, arrange and omit illustrated bonding agent.Herein, wiring is the sheet member that formed by the material identical with wiring portion 3 with conductive sheet 30.
Below, such as by dry lamination method etc., this duplexer being fitted.
Then,, as shown in Fig. 2 (b), the wiring in the duplexer after laminating is carried out to patterning and formed wiring portion 3 with conductive sheet 30.
As patterning method, such as with conductive sheet 30 metallic foil sheets such as be Copper Foil in the situation that, adopting etching method in wiring.; in wiring, with after painting erosion resistant agent on conductive sheet 30, according to the mode of the wiring pattern corresponding to wiring portion 3, resist is carried out to patterning, and by chemical solution etching; the wiring not covered by resist is removed with conductive sheet 30, thereby form wiring portion 3.Resist wiring portion 3 in removed thereafter.
By such operation, form the duplexer of protective layer 1 and wiring sheet material 4.
In addition, such duplexer also can, after forming wiring sheet material 4, form at the back side of sheet substrate 2 2a splice protection layer 1.
Then, as shown in Figure 3, on the duplexer of protective layer 1 and wiring sheet material 4, overlap rear side diaphragm seal 35A.
Rear side diaphragm seal 35A is owing to forming rear side sealing 5A, because of but the sheet member that formed by the material identical with rear side sealing 5A.In side seal sheet 35A, the setting position of the connecting electrode 6a of solar battery cell 6, is formed with the through hole 5a connecting at thickness direction relatively overleaf.Through hole 5a has the shape that can hold connecting electrode 6a, and has the size of following degree, and described degree is the degree overlapping the state that this connecting electrode 6a can not overflowed from the wiring portion 3 of connected position.
Thus, each through hole 5a is formed with the concavity portion that utilizes wiring portion 3 to stop up below.
Then, in the wiring portion 3 in through hole 5a, link 9 is set.For example,, in the situation that link 9 is soldering paste and/or silver paste, by be coated with necessary amounts setting in through hole 5a.
Then, be provided with in this wise on the duplexer of rear side diaphragm seal 35A mounting solar battery cell 6.Now, about each solar battery cell 6, with each connecting electrode 6a, be inserted into the state setting in through hole 5a.
Then, according to and rear side diaphragm seal 35A between the mode of solar battery cell 6 clamping is loaded to sensitive surface side seal sheet 35B, and further on sensitive surface side seal sheet 35B, load light-transmitting substrate 7 (with reference to Fig. 4).
Herein, sensitive surface side seal sheet 35B is owing to forming sensitive surface side seals 5B, because of but the sheet member that formed by the material identical with sensitive surface side seals 5B.
By such operation, form by protective layer 1, wiring sheet material 4, rear side diaphragm seal 35A, solar battery cell 6, sensitive surface side seal sheet 35B and light-transmitting substrate 7 are stacked gradually to the duplexer 50A obtaining.
Then, use laminating machine, while heat duplexer 50A, in stacked direction pressurization, carry out lamination.
Heating-up temperature is now to make rear side diaphragm seal 35A, sensitive surface side seal sheet 35B occur softening and be out of shape, and can be close to the surface of adjacent parts and bonding temperature respectively, and is to make link 9 be incorporated into the temperature of wiring portion 3 and connecting electrode 6a.
Such heating-up temperature is also relevant with the material of rear side diaphragm seal 35A, sensitive surface side seal sheet 35B, link 9, but can be for example the temperature of 125 ℃～160 ℃ of left and right.
Therefore, compare with need the structure of the insulating barrier that comprises solder resist of the heating-up temperature of 120 ℃～160 ℃ of left and right in order to carry out heat cross-linking after printing, the heating when it does not need to carry out except lamination, so heat load can be seldom.Easily prevent thus not good phenomenon as follows: it is deteriorated that the raw material (material) that form solar module carry out heat, or cause dimensional stability variation because of thermal contraction.
Utilize such heating, give as security to press, the inside of the through hole 5a of side seal sheet 35A overleaf, and be held under the state of wiring portion 3 and connecting electrode 6a, each link 9 is given as security and pressed at stacked direction, thereby be close to wiring portion 3 and connecting electrode 6a.Thus, rear side diaphragm seal 35A is bringing into play that the connecting electrode 6a that has prevented from softening moves and the function that is attached to the position except wiring portion 3.
In addition, rear side diaphragm seal 35A and sensitive surface side seal sheet 35B are softening under flowable state respectively, thereby are close to the surface of adjacent parts respectively.Thus, rear side diaphragm seal 35A and sensitive surface side seal sheet 35B become be filled between wiring sheet material 4 and solar battery cell 6, between solar battery cell 6 and light-transmitting substrate 7, the state between each wiring portion 3, between each connecting electrode 6a, and form respectively rear side sealing 5A, sensitive surface side seals 5B.
By such operation, when heating finishes,, solidifying under the state of each layers cementing of duplexer 50A, form solar module 50 as shown in Figure 1.
According to the solar module 50 of present embodiment, by forming the rear side sealing 5A of a part for sealing 5, shielded the outer surface of wiring portion 3, connecting electrode 6a and link 9, thus positively with spaced other charging part electric insulation.In addition, link 9 during by wiring portion 3 and connecting electrode 6a conducting, can be fixed on link 9 scope of the through hole 5a of rear side sealing 5A, thereby can suppress the movement of link 9.
Thus, for example, with except arranging the encapsulant of solar module 50 sealing, the insulating barrier being formed by solder resist is also set and realize the electric insulation of wiring portion 3, the structure that prevents from being attached to the position that does not need scolder is compared, and can be made into simple structure.
In addition, because solder resist has Thermocurable, thereby need to be before carrying out operation solar battery cell 6 being sealed by lamination, the operation that setting is cured, but the rear side sealing 5A of present embodiment be take thermoplastic resin as main component, thereby can together pass through lamination and sealed solar energy battery unit 6 with sensitive surface side seals 5B, can moulding simultaneously when the electrical connection of carrying out based on link 9.
