The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

First embodiment is used to build the photovoltaic hollow glass curtain wall component on surface on the sunny side, sees Fig. 2-Fig. 4.

This example is on the ultrawhite tempered glass 13 consistent with the curtain wall contour shape, lay bonding agent 12, solar cell 6, bonding agent and backboard 11 consistent with ultrawhite tempered glass shape, undersized successively, its dorsulum can be shades of colour or transparent insulation materials.After each solar cell is connected in series in groups respectively, draw lead-out wire 10, and connect bypass diode 3 separately by a side of backboard.In the backboard edge portion of each solar panel lead-out wire 10 position respective width, make the right angle N shape 15 that to block this place's lead-out wire and connection, extension laterally and bending.By lamination ultrawhite tempered glass 13, bonding agent 12, solar cell 6 and backboard 11 are formed photovoltaic module.Be provided with at the back side of photovoltaic module backboard aluminium chassis 8 and with the bottom glass 7 of the same size of ultrawhite tempered glass, bonding is fixing successively, is formed on the hollow layer 14 between bottom glass and the photovoltaic module.Also formed the outside simultaneously, at the ultrawhite tempered glass of photovoltaic module and the circuit groove 16 between the bottom surface glass 7 around curtain wall edge portion, aluminium chassis 8.Bottom glass 7 can be doubling glass or versicolor tempered glass.The joint of lead-out wire 10 and cable 1 must place between back veneer material extension and dogleg section and the tempered glass 13, makes the isolation insulated from each other of circuit and aluminium chassis.In the circuit groove of solar cell lead-out wire side, lay output snap joint 5, total output cable 1, each solar panel lead-out wire 10, the bypass diode 3 of total output cable and be used to connect, heat-shrink tube 4 or plastic pipe sleeve envelope that insulating properties are good, cable 1 needs be fixed on ultrawhite tempered glass 13 back sides with ply-yarn drill 2.Whole circuit groove is filled sealing with all good silica gel 9 of weatherability, insulating properties, sealing, and lead-out wire and each joint of cable run are packaged in the circuit groove within the assembly profile by silica gel in the lump.

During work, the sunshine that sees through photovoltaic hollow glass curtain wall component makes solar cell work, powers to the power load end through cable.Under by the isolation of extending with dogleg section 15, make between the lead-out wire that exceeds backboard edge portion and the aluminium chassis still to keep insulation; Diode can the bypass battery the hot-spot electric current, prevented the hot spot generation.At photovoltaic hollow glass curtain wall component edge, in the space of the circuit groove that is surrounded by two the edge endless belt and the aluminium chassis outside of bottom glass, ultrawhite tempered glass, laid the necessary conducting wire of solar cell work.Draw lead-out wire from the backboard back side, photovoltaic module can be made routinely.

Simultaneously, because backboard no longer adopts glass, can alleviate the overall weight of curtain wall.With a 1000mm * 1000mm curtain wall is example, selects glass insulating back panel in addition for use, than the curtain wall of backboard employing glass material, can reduce about 30% (relevant with the thickness of glass that adopts) on weight.

This curtain wall construction is for every square meter, deducts blocking of periphery one circle fluid sealant and solar cell, and the shading rate of curtain wall component is controlled at about 0.6, and this curtain wall component power is about 80W.

Second embodiment sees Fig. 1.This example is in full accord with the first routine basic structure, and just the snap joint 5 of its cable connection is drawn out to outside the assembly, and all the other are identical with last example.

The 3rd embodiment sees Fig. 5, its structure and first example are basic identical, and just the lead-out wire of solar panel is distributed within the circuit groove 16 on curtain wall both sides, and lead also is attached thereto in the relevant position, except that two circuit grooves, the external connection in two places were arranged, all the other were all consistent with precedent.

The 4th embodiment sees Fig. 6 and Fig. 7.This routine structure and precedent basically identical, just backboard all exceeds aluminium chassis outer rim side in the total length of its edge portion, and all to the bending of curtain wall bottom glass side, the formation another kind has only a right angle but width prolongs and the extension of the whole girths of backboard and bending form 15, the aluminium chassis adjacent side is all blocked, make insulation more complete, the layout of the lead-out wire of also being more convenient for and site operation.All the other situations are all consistent with precedent.
