Abstract

The utility model provides a BIPV solar cell module which comprises a glass back plate and outer layer glass. A plurality of solar cells which are connected through interconnection bars are arranged between the glass back plate and the outer layer glass. The glass back plate is sintered and fastened with a grid-like silver-contained conducting wire layer. The solar cells are welded on the silver-contained conducting wire layer. Aluminum strips are arranged between the periphery of the glass back plate and the periphery of the outer layer glass and are coated with sealing glue. The BIPV solar cell module has the advantages that: (1) compared with a traditional module, an EVA or PVB film is reduced, the cost is reduced, and the transparency is increased; (2) the production process is simple, and the production efficiency is raised; (3) the silver-contained conducting wire layer is difficult to be oxidized and is difficult to fall off, and the service life of the module is prolonged.

Description

The BIPV solar module

Technical field

The utility model belongs to photoelectricity and building materials field, relates in particular to a kind of BIPV solar module.

Background technology

At present, along with the development of society, solar energy also more and more is subjected to people's attention as clean energy resource.BIPV (Building Integrated PV) is called for short BIPV, is exactly with the part of photovoltaic module as building, brings into play its electricity generate function simultaneously.Because photovoltaic generating module and building combination be outer ground and the space of occupying volume not, is the best mounting means of photovoltaic generating system extensive use in the city.And the BIPV solar module is exactly as a kind of construction material, can integratedly be applied in curtain wall, daylighting roof, the building structure of bicycle shed ceiling light, has generating, sound insulation, Wind-Pressure Resistance, characteristic such as high temperature resistant.In application, the light transmission of BIPV solar module also is very important.

Comparatively common BIPV solar module generally adopts glass as backboard now, lays one deck EVA or PVB glued membrane then, puts the battery sheet, lays one deck EVA or PVB glued membrane again, covers glass at last, heated lamination.Light can see through at the interval between the battery sheet, but because the existence of EVA glued membrane or PVB glued membrane, has influenced the light transmittance of assembly, influence the interior light of building.

Summary of the invention

For solving above technical deficiency, the utility model provides a kind of BIPV solar module method, and its production process is simple, and production efficiency is expensive low, the light transmission height.

The utility model is realized by following measure:

A kind of BIPV solar module of the present utility model comprises glass back plate and glass outer, institute

State and be provided with some solar battery sheets that connect by interconnector between glass back plate and the glass outer, sintering is fastened with latticed argentiferous conductor layer on the described glass back plate, described solar battery sheet is welded on the argentiferous conductor layer, is provided with the aluminium parting bead between glass back plate and the glass outer edge and is wiped with fluid sealant.

Cavity between above-mentioned glass back plate and the glass outer is the nitrogen chamber.

Above-mentioned argentiferous conductor layer is the mixture of silver slurry and glass dust.

Above-mentioned argentiferous conductor layer width is 3mm, and thickness is 0.1 ~ 0.3mm.

Above-mentioned aluminium parting bead adopts and fills molecular sieve and antioxidant in the aluminium frame

The beneficial effects of the utility model are: 1. compare with traditional assembly, reduced EVA or PVB glued membrane, it is low to have reduced cost, has increased light transmission; 2. manufacture craft is simple, has improved production efficiency; 3.

The argentiferous conductor layer is difficult for oxidized, and difficult drop-off, has prolonged the useful life of assembly.

Description of drawings

Fig. 1 is the structural representation of invention.

Wherein: 1 glass outer, 2 nitrogen chambeies, 3 aluminium parting beads, 4 fluid sealants, 5 argentiferous conductor layers, 6 glass back plate, 7 solar battery sheets, 8 interconnectors.

Embodiment

As shown in Figure 1, a kind of BIPV solar module of the present utility model, comprise glass back plate 6 and glass outer 1, sintering is fastened with latticed argentiferous conductor layer 5 on the glass back plate 6, the solar battery sheet 7 that connects by interconnector 8 is arranged on the glass back plate 6, and solar battery sheet 7 is welded on the argentiferous conductor layer 5, covers glass outer 1.Be provided with aluminium parting bead 3 and be wiped with fluid sealant 4 between glass back plate 6 and glass outer 1 edge.Cavity between glass back plate 6 and the glass outer 1 is nitrogen chamber 2.Argentiferous conductor layer 5 is the mixture of silver slurry and glass dust.Argentiferous conductor layer 5 width are 3mm, and thickness is 0.1 ~ 0.3mm.

Concrete making step is as follows:

A. with plate glass cutting, edging, cleaning, drying, standby as glass back plate 6 and glass outer 1;

B. use to contain silver paste, utilize the argentiferous conductor layer 5 of screen printing forme method print grid shape on glass back plate 6, wherein contain silver paste and be the mixture of silver slurry and glass dust; Silk screen in the screen printing forme adopts 270 ~ 300 orders.

C. the glass back plate 6 that is printed with argentiferous conductor layer 5 among the step b is dried and heat treatment, argentiferous conductor layer 5 sintering are fastened on the glass back plate 6, wherein glass back plate 6 adopts horizontal annealing furnace to heat-treat, and temperature is 480 ℃ ~ 520 ℃, and heat treatment time is 20 ~ 30 seconds.

D. lay the solar battery sheet 7 that is weldingly connected by interconnector 8 on the glass back plate 6 after step c being handled, and with

solar battery sheet

7 and 5 welding of argentiferous conductor layer;

E. glass outer 1 is fitted on the glass back plate 6 after steps d is handled, edge between glass back plate 6 and glass outer 1 embeds aluminium parting bead 3 as supporting and spread ground floor fluid sealant 4, then the cavity between glass back plate 6 and the glass outer 1 is evacuated to 0.6 atmospheric pressure, inflated with nitrogen to 1 atmospheric pressure, and then be evacuated to 0.6 atmospheric pressure, charge into nitrogen to 1 atmospheric pressure again, the shutoff pore also is coated with second layer fluid sealant 4.The aluminium parting bead adopts and fills molecular sieve and antioxidant in the aluminium frame, to absorb steam, anti-oxidation.

Containing silver paste is to be mixed and made into by silver slurry and glass dust.Wherein parts by weight of raw materials is, silver slurry: 60 ~ 80 parts; Glass dust: 20 ~ 40 parts.

The thick slurry of a kind of mechanical mixture that silver slurry system is made up of particulate, adhesive, solvent, the auxiliary agent of highly purified (99.9%) argent.Because the feature oxidation number of silver be+1, its activity is than copper difference, under the normal temperature, even when heating also not with water and air in the oxygen effect.So it is oxidized that argentiferous conductor layer 5 is not easy, thereby can keep conductivity and be not easy to come off because of oxidation.

Glass powder is unformed hard particles, contain SiO2 etc., after glass powder and silver powder be mixed into liquid slurry, through high-temperature process, glass powder and glass back plate 6 can be carried out solid phase reaction by Yin Gaowen, form the glass isotropic body of disordered structure, thereby sintering are on glass back plate 6, chemical property is stable, is not easy to come off.

The above only is the preferred implementation of this patent; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the art of this patent principle; can also make some improvement and replacement, these improvement and replacement also should be considered as the protection range of this patent.
