Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, further set forth the utility model below in conjunction with specific embodiment.
Embodiment 1
Referring to Fig. 1 and 2, large space of a whole page splicing thin-film solar cells laminated glass, comprise two square solar battery glass 110 in unit, the square solar battery glass in unit comprise interior toughened glass layer 111 and outer toughened glass layer 113 and be arranged on interior toughened glass layer and outer toughened glass layer between thin-film solar cells glassy layer 112.
Between interior toughened glass layer 111 and thin-film solar cells glassy layer 112, all be connected by film 113 between outer toughened glass layer 113 and thin-film solar cells glassy layer 112.In the utility model, film 113 is PVB film or SGP film.With the EVA film in photovoltaic module in the past, compare, there is better sunlight transmitance, bonding, heat-resisting, cold-resistant, moisture-proof, the characteristics such as mechanical strength height, can prevent that alluvium from penetrating, even glass breakage, fragment also can firmly stick on the intermediate coat film, can not come off to scatter and hurt sb.'s feelings, thereby the injury produced may be reduced to a minimum, improve the security performance of building.As the thin-film solar cells glassy layer 112 in intermediate layer, can according to customer demand carry out the size customization, directly adopt wire 114 to be connected, wire is connected with external wire 116, has solved the little restricted problem of thin film solar glass size.For the ease of the laying of wire 114, between the forward surface of interior toughened glass layer and thin-film solar cells glassy layer, be provided with for burying the Baltimore groove of wire underground.The large space of a whole page splicing thin-film solar cells laminated glass of this structure, good result with aesthetics of architecture, all wiring all are hidden in Baltimore groove, after having beaten structure glue or weather-resistant glue, from the front of glass, can't see any wire, can not affect the appearance effect of building, can prevent direct sunlight and rain erosion, hull cell is spliced, met the size customization requirement of personalized building, reached the perfect adaptation with building.
The square solar battery glass composite assembly in a plurality of unit becomes the plate type integrated structure of three layers, the space of a whole page size of the thin-film solar cells glassy layer of the square solar battery glass of peripheral cell of plate type integrated structure is less than the space of a whole page size of interior toughened glass layer and outer toughened glass layer, cause and define a gap frame between the ectonexine of plate type integrated structure, be filled with the colloid 115 that connects fastening and sealing function in the frame of gap.In the present embodiment, colloid is structure glue or weather-resistant glue.Solve the defect of the easy oxidation of solar energy film (blow-by) by colloid 115, improved the reliability of assembly.
Use PVB film or the SGP film intermediate coat as laminated glass; adopt the processing technology of roll-in method or vacuum method to carry out the exhaust precompressed; carry out the HTHP typing through autoclave process again; this structure has improved whole intensity and impact resistance greatly; the thin-film solar cells glassy layer 112 of non-tempering is between interior toughened glass layer 111 and outer toughened glass layer 113; be subject to the protection of interior toughened glass layer 111 and outer toughened glass layer 113; solve the breakable problem of original thin film solar glass, greatly increased the intensity of glass assembly.
The thickness of interior toughened glass layer 111 and outer toughened glass layer 113 can be selected according to actual service condition, to meet the requirement of strength of building curtain wall.Large space of a whole page splicing thin-film solar cells laminated glass of the present utility model can be combined with roof, be combined with exterior wall, be combined with solar protection devices, or does glass curtain wall and use.Outer toughened glass layer can generally adopt ultrawhite toughened glass, and interior toughened glass layer 111 can adopt dissimilar glass (as online LOWE, off-line LOWE, colored glazed glass, ultra-clear glasses etc.), to reach different results of use.
In building curtain wall, the square solar battery glass of this element can also be combined with as the sheet of joining of double glazing, greatly reduces the thermal transmission coefficient (U value) of glass, improves the energy-saving effect of building.
