Development along with solar battery technology, thin-film solar cells based on non-crystalline silicon series has appearred, it is a kind of non-crystalline silicon flexible thin-film solar cell assembly that utilizes non-crystalline silicon to process in conjunction with the PIN photodiode technology, one of maximum difference of it and traditional crystal silicon solar energy battery can utilize the material of light weight softnesses such as corrosion resistant plate or various polymer as substrate exactly, make it to have softness, frivolous, durable advantage, and manufacturing process is simple relatively, thereby cost is lower; The choice of substrate is big, suitable large tracts of land suitability for industrialized production.The more existing crystal silicon solar energy battery of photovoltaic output characteristics of this non-crystalline silicon flexible thin-film solar cell assembly will be got well, and not only can utilize the generating of solar energy direct irradiation, can also utilize surround lighting to realize low light level generating; Its surface seals to prevent that water and oxygen from entering with diaphragm as thin as a wafer, and the generating life-span reached more than 20 years.The present inventor just is being based on this novel solar cell, develop a kind of simple in structure, suitable for mass production, novel building roofing easy to utilize with watt, satisfy the needs in market.
The utility model content
The technical problems to be solved in the utility model is at the deficiencies in the prior art, and a kind of simple in structure, low cost of manufacture, solar energy power generating easy to install watt are provided.
The technical solution of the utility model is: a kind of solar photovoltaic power generation roofing watt, comprise base material, wherein, described base material external surface posts non-crystalline silicon flexible thin-film solar cell component layer, be provided with electric energy at the base material inwall and draw junction box, junction box is connected with non-crystalline silicon flexible thin-film solar cell component layer circuit.
In the above-mentioned solar photovoltaic power generation roofing watt, described base material is one of them of metal Roof watt or cement roof watt or composite roof watt.
In the above-mentioned solar photovoltaic power generation roofing watt, also be provided with adhesive layer between described base material and the non-crystalline silicon flexible thin-film solar cell component layer.
Said structure roof tile of the present utility model, be that direct applying of non-crystalline silicon flexible thin-film solar cell assembly or hot pressing are formed at traditional roof tile external surface, thereby can utilize existing multiple roof tile material and technology, directly processing and manufacturing BIPV (Building Integrated PV) building roof watt or roof board material, do not need the specific matrix structure member of design in addition, reduce its manufacturing cost greatly; And the BIPV (Building Integrated PV) building roof of processing and manufacturing thus, its mounting method and traditional construction material are basic identical, help applying of solar energy more, utilize solar electrical energy generation significant to building roofing.

The specific embodiment
Embodiment 1
Consult shown in Figure 1, solar photovoltaic power generation roofing of the present utility model watt, comprise backing material plate 1, backing material plate 1 is a color profiling steel plate watt, post non-crystalline silicon flexible thin-film solar cell component layer 2 at base material 1 external surface, paste formation integral body by hot pressing between base material 1 and the non-crystalline silicon flexible thin-film solar cell component layer 2; Be provided with electric energy at base material 1 inwall and draw junction box 3, junction box 3 is connected with non-crystalline silicon flexible thin-film solar cell component layer 2 circuit.
Embodiment 2
Consult shown in Figure 2, solar photovoltaic power generation roofing of the present utility model watt, comprise backing material plate 1, backing material plate 1 is cement composite material watt goods, post non-crystalline silicon flexible thin-film solar cell component layer 2 at base material 1 external surface, between base material 1 and non-crystalline silicon flexible thin-film solar cell component layer 2, paste by adhesive layer 4; Be provided with electric energy at base material 1 inwall and draw junction box 3, junction box 3 is connected with non-crystalline silicon flexible thin-film solar cell component layer 2 circuit.
Embodiment 3
Consult shown in Figure 3, solar photovoltaic power generation roofing of the present utility model watt, comprise backing material plate 1, base material 1 is clay tile or potlery tile, post non-crystalline silicon flexible thin-film solar cell component layer 2 at base material 1 external surface, paste by adhesive layer 4 between base material 1 and the non-crystalline silicon flexible thin-film solar cell component layer 2; Be provided with electric energy at base material 1 inwall and draw junction box 3, junction box 3 is connected with non-crystalline silicon flexible thin-film solar cell component layer 2 circuit.
Embodiment 4
Consult shown in Figure 4, solar photovoltaic power generation roofing of the present utility model watt, comprise backing material plate 1, base material 1 is for adding the thermoplastic composite engineering plastics section bar roof panel that the space structure forms with makrolon material, post non-crystalline silicon flexible thin-film solar cell component layer 2 at base material 1 external surface, paste by adhesive layer 4 between base material 1 and the non-crystalline silicon flexible thin-film solar cell component layer 2; Be provided with electric energy at base material 1 inwall and draw junction box 3, junction box 3 is connected with non-crystalline silicon flexible thin-film solar cell component layer 2 circuit.
When the utility model specifically uses, because base material 1 is directly to utilize traditional roof tile or moulding roof panel system, can directly be installed in the roof as the roofing materials of building, its mounting method and traditional Roof system are basic identical, just need when mounted the junction box 3 of every block of base material 1 inwall to be carried out circuit and connect combination (string or parallel circuit connect), then circuit is connected to inverter and changes direct current into alternating current, the switchbox in being installed in building is served electrical network (use of being incorporated into the power networks) or is directly offered building load electricity consumption.
