As shown in Figure 2, according to the application's a preferred implementation, a kind of film solar battery module mainly comprises: cell panel 1, and attaching (for example bonding) is in supporting rail 20 and the terminal box of cell panel dorsal part.
In addition, film solar battery module can also comprise frame, and it surrounds the periphery of cell panel 1, so that the protection cell panel.
In the illustrated embodiment, cell panel 1 in the form of a substantially rectangular, thereby limit vertical (direction that is parallel to the long limit of rectangular panel) of cell panel and laterally (direction that is parallel to the minor face of rectangular panel).In addition, under real use state, described cell panel 1 has in the face of the front side of sunlight with back to the dorsal part of sunlight.Schematically illustrate the dorsal part structure of cell panel 1 in Fig. 2.
for example, according to the cell panel 1 of the application's film solar battery module along the direction to dorsal part mainly comprises from the front side: the battery cladding plate is (for example by glass, the formations such as polymer), be attached to the battery lamella (amorphous silicon type of battery cladding plate dorsal part, the microcrystal silicon type, dye-sensitized dye-type, organic type, the copper indium diselenide type, the Copper Indium Gallium Selenide type, tellurium is every film etc.), be positioned at vertical busbar 2 of back surface vertical both sides of battery lamella, the dorsal part encapsulated layer of clad battery lamella dorsal part and busbar, cover the backboard of dorsal part encapsulated layer dorsal part (for example by glass, polymer, the formations such as metal).

Supporting rail 20 can be made by suitable plastics or metal material.For example, supporting rail can be plastics or metal extrusion molding part, metallic plate punching molded part etc.Supporting rail is provided with suitable mounting structure, and for example installing hole, buckle structure etc., be used for supporting rail is fixed to bearing structure.
Be appreciated that the quantity of supporting rail and distribute and be not limited to shown in figure.For example, for large-scale film solar battery module, can attaching more (for example four) supporting rail longitudinally.In addition, as the additional of two longitudinal bracing rails shown in figure or substitute, can adopt horizontal supporting rail.
Battery lamella in cell panel 1 is comprised of a plurality of cell pieces that extend longitudinally, laterally connect.The electric current that these cell pieces produce is pooled to terminal box by the vertical busbar 2 that extends longitudinally along the edge, the left and right sides (longitudinal extension edge) of cell panel respectively.
According to execution mode shown in Figure 2, two continuous supporting rails 20 are attached to the cell panel dorsal part near the edge, the left and right sides of cell panels (namely roughly corresponding to the vertical position of busbar 2), and terminal box is formed by two the terminal box part 10-1 and the 10-2 that are combined in two supporting rails 20.
In each terminal box part 10-1 and 10-2, be provided with corresponding conducting wire, be used for being electrically connected to two vertical busbars 2 respectively.For this reason, on the position corresponding with each terminal box part, preferably on by the position of each terminal box partial coverage, offer little through hole (not shown) in the backboard of cell panel 1.The respective through hole that the lead-in wire (not shown) that is connected with two vertical busbars 2 respectively passes in dorsal part encapsulated layer and backboard extends to the backboard dorsal part, and enters in corresponding terminal box part.Described lead-in wire can be connected to the conducting wire in corresponding terminal box part, perhaps, can be made of described lead-in wire at least a portion of conducting wire.
In two terminal boxes part one for example is equipped with bypass diode 12 in the conducting wire in the left side terminal box part 10-1 shown in figure, in order to prevent that opening circuit from appearring in solar module or the situation of inverse current impulse.
It may be noted that about aerial lug 6, here so-called " outside ", refer to for the horizontal busbar that is arranged on cell panel inside in prior art, the lines between two terminal boxes part of being connected in that use in each execution mode of the application are positioned at the cell panel outside.The application does not get rid of the situation that aerial lug 6 is sealed or covered by the other parts (for example frame) of film solar battery module.
Both positive and negative polarity output cable 14 is connecting respectively the anode and cathode terminals of terminal box.Described anode and cathode terminals also is connected to the two ends of bypass diode 12.
In example shown in Figure 2, the positive terminal of terminal box is arranged on the terminal box part 10-1 of left side, the negative terminal of terminal box is arranged on the terminal box part 10-2 of right side, namely negative terminal is connected with conducting wire in the terminal box part 10-2 of right side.Like this, both positive and negative polarity output cable 14 is drawn from left side terminal box part 10-1 and right side terminal box part 10-2 respectively.
As an alternative, the anode and cathode terminals of terminal box can all be positioned on the terminal box part 10-1 of left side.Like this, two output cables 14 are all drawn by left side terminal box part 10-1.

According to the execution mode shown in Fig. 2, two terminal boxes partly are combined on left and right sides supporting rail 20.When bonding to two supporting rails on cell panel 1, also terminal box is bonded on cell panel 1 simultaneously.Like this, needn't respectively terminal box and supporting rail be bonded on cell panel as prior art, so the assembly operation of film solar battery module is simplified.
In addition, owing to offering respectively two little through holes in the backboard of cell panel, the cross-sectional area sum of these two through holes is still less than one that offers in prior art shared large otch.Therefore, the backboard loss of strength that causes of these two through holes is less than prior art.
According to the application, both positive and negative polarity output cable 14 can be connected to a terminal box part, also can be connected respectively to two terminal box parts.Like this, can according to the arrangement of film solar battery module, and other film solar battery module between connected mode etc. select the mode of connection of both positive and negative polarity output cable, thereby the flexibility that has improved the film solar battery module mode of connection.
According to the application's preferred implementation, each terminal box part can form with corresponding supporting rail.For example, can form simultaneously terminal box part and supporting rail by injection-moulding plastic etc.In this case, the material of terminal box part can be identical or different with supporting rail.
Perhaps, each terminal box part can be separated formation with supporting rail, and is assembled into together.For example, supporting rail is the metal extrusion profile, and terminal box is working of plastics, terminal box by bonding, chimeric, by means of securing member etc. and be combined in supporting rail, or when injection moulding terminal box part with its straight forming and be fixed on supporting rail.
The material of terminal box is preferably the plastics of insulation, for example is selected from least a in following one group: polyester (as PETG, polybutylene terephthalate or PTT), polycaprolactam, polyamide (as polyamide 66, polyamide 46 or Nomex), Merlon, the acrylonitrile/butadiene/styrene copolymer, polyurethane, polyphenylene oxide, polymeric liquid crystal copolymer, Polyetherimide, polyvinyl chloride, or its blend etc.
The material of supporting rail is preferably aluminium, aluminium alloy, stainless steel, plastics etc.For the supporting rail of shape form, can adopt aluminum or aluminum alloy to make by extrusion molding, perhaps adopt other sheet metal to make by punching press, the mode such as rolling.Certainly, the supporting rail of other form also can adopt.
Because terminal box and supporting rail are combined, so this bonding strength on cell panel of terminal box also improved, even long-term the use also is not easy to break away from from cell panel.
In execution mode shown in Figure 2, each terminal box partly is combined in a corresponding supporting rail.Yet, according to the application's basic principle, can only have a terminal box to be partially integrated in corresponding supporting rail.
In execution mode shown in Figure 2, each supporting rail is located in a lateral direction partly overlapping with corresponding vertical busbar position.Yet supporting rail also can be fully overlapping with corresponding vertical busbar in a lateral direction, or fully not overlapping with busbar.
According to the application's a execution mode, supporting rail is made of the part of the frame of cell panel.Like this, by frame being assembled on the cell panel edge, also just supporting rail and terminal box have been fixed on cell panel simultaneously, thereby have further simplified structure and the assembling process of film solar battery module.
In execution mode shown in Figure 2, each terminal box partly lays respectively at the roughly vertically central of respective support rail.Yet, terminal box partly can be combined in any position of supporting rail.For example, consider the convenience of wiring, terminal box part can near or be positioned at vertical end (especially lower end) of supporting rail.
Two terminal box parts location optimization in the vertical is substantially the same.Certainly, the application does not get rid of two terminal box parts different situation in position in the vertical.
For example, in another execution mode of film solar battery module of the application shown in Figure 3, consist of each terminal box part 10-1 of terminal box and the vertical end (especially lower end) that 10-2 was combined in or consisted of respective support rail 20.Compare with the execution mode in Fig. 2, this execution mode in Fig. 3 can shorten the length of both positive and negative polarity output cable 14, and is convenient to the wiring operation on the terminal box part of both positive and negative polarity output cable 14 and aerial lug 6.
The other side of film solar battery module execution mode shown in Figure 3 and shown in Figure 2 similar is not described in detail here.
Other execution mode that has shown the application's film solar battery module in Fig. 4-6.Not show both positive and negative polarity output cable in order simplifying in these figure, but to be appreciated that both positive and negative polarity output cable can be connected in one or two terminal box parts for Fig. 2,3 modes of describing in the front.
Shown in the execution mode of the film solar battery module that Fig. 4 shows and Fig. 2,3, the maximum difference of execution mode is, each supporting rail 20 is segmented.In illustrated example, each supporting rail 20 comprises two sections that vertically align, and the outer lateral boundaries edge of every section supporting rail is concordant with the edge, the left and right sides of cell panel 1 respectively, thereby along laterally fully overlapping with corresponding vertical busbar.
Yet, be appreciated that the support requirement according to cell panel, any multistage that supporting rail can be included in the optional position, distribute along various directions.
For this segmented supporting rail, each terminal box partly is arranged in corresponding one section supporting rail.
Adopt the benefit of segmented supporting rail to be, the position that can support at the needs of cell panel arranges arbitrarily the supporting rail section, and all the same Fig. 2 of total length, 3 illustrated embodiment of supporting rail section are compared even and may be shortened.Therefore, the execution mode in Fig. 4 can improve supporting rail to the support strength of cell panel, and reduces the material usage of supporting rail.
In addition, for execution mode shown in Figure 4, there is such possibility, namely do not need the backboard of cell panel is punched.Particularly, the lead-in wire that is connected with two vertical busbars 2 can be drawn by the edge, the left and right sides of cell panel 1 (the dorsal part encapsulated layer that for example passes cell panel), and is connected to the conducting wire in corresponding terminal box part 10-1 and 10-2 or consists of at least a portion of this conducting wire.In this case, owing to need to not punching on backboard, therefore, the intensity of backboard can not reduce, and does not need to carry out the seal operation relevant to through hole.The lead-in wire that is connected with two vertical busbars 2 can seal with respect to cell panel by the dorsal part encapsulated layer of cell panel itself.Therefore, execution mode shown in Figure 4 can further be simplified structure and the assembly operation of film solar battery module.
Similar shown in the other side of film solar battery module execution mode shown in Figure 4 and Fig. 2,3 is not described in detail here.
Fig. 5 has shown another execution mode of the application's film solar battery module, and this film solar battery module mainly comprises: cell panel 1, and attaching (for example bonding) is in supporting rail 20 and the terminal box of cell panel dorsal part.
Terminal box is made of terminal box part 10-1 and 10-2.These two terminal boxes partly are arranged at a transversely-extending edges (especially lower limb) of cell panel 1 and locate, and are positioned at and the longitudinal end of two vertical busbars 2 of cell panel 1 corresponding position roughly.Aerial lug 6 is together in series the conducting wire of two terminal box part 10-1 and 10-2.
In addition, the supporting rail 20 of segmented is arranged on by corresponding vertical busbar 2 laterally inwardly on the position at interval.Execution mode in same Fig. 2-4 is compared, due to the horizontal inboard skew of the supporting rail 20 in this example towards cell panel 1, and needn't be close or overlapping with vertical busbar 2 at least in part, therefore can improve supporting rail to the supporting role of cell panel 1, and improve the distribution flexibility of supporting rail.
Two terminal box parts that show in Fig. 5 all are positioned at the outside of the lower limb of cell panel 1 at least in part, and for example, two terminal boxes partly are attached on the lower limb of cell panel 1.As a kind of optional execution mode, two terminal boxes part can attaching on the frame of the lower edge of cell panel 1.
Perhaps, two terminal boxes part can be positioned at the inboard of the lower limb of cell panel 1, for example is attached to fully on the backboard back side of cell panel.
In order to realize being electrically connected between two vertical busbars 2 and two terminal box part 10-1 and 10-2, the lead-in wire that is connected with two vertical busbars 2 can be drawn by the lower limb of cell panel 1 (the dorsal part encapsulated layer that for example passes cell panel), and is connected to the conducting wire in corresponding terminal box part 10-1 and 10-2 or consists of at least a portion of this conducting wire.Described lead-in wire can seal with respect to cell panel by the dorsal part encapsulated layer of cell panel.
Perhaps, vertical lower end of two vertical busbars 2 is extended to outside the lower limb of cell panel 1, thereby form the prolongation of vertical busbar, described prolongation is directly connected to the conducting wire in corresponding terminal box part or consists of at least a portion of this conducting wire.Vertically the prolongation of busbar 2 can seal with respect to cell panel by the dorsal part encapsulated layer of cell panel.
Therefore, pass the lead-in wire of cell panel lower limb or vertically the busbar prolongation consisted of the conductive part that realization is electrically connected between vertical busbar and terminal box part.
In both cases, need to not punch on backboard, therefore, the intensity of backboard can not reduce, and does not need to carry out the seal operation relevant to through hole.Like this, same Fig. 2,3 illustrated embodiment are compared, and execution mode shown in Figure 5 can further be simplified structure and the assembly operation of film solar battery module.
In execution mode shown in Figure 5, two terminal boxes partly are arranged at a transversely-extending edges place of cell panel.Yet, according to the application's basic principle, can only have a terminal box partly to be arranged at a transversely-extending edges place of cell panel.
