Abstract

The utility model relates to a solar cell module with high transmission on a forward direction and high reflection on a backward direction. The solar cell module comprises a piece of glass (1), a first layer glue film (2), a battery string (3), a second layer glue film (4), and a backboard (5). The piece of glass (1), the first layer glue film (2), the battery string (3), the second layer glue film (4), and the backboard (5) are arranged and laminated from top to bottom in sequence. The solar cell module is characterized by also comprising a forward high transmission and backward high reflection film (6). The forward high transmission and backward high reflection film (6) is disposed between the piece of glass (1) and the first layer glue film (2). Through adding the forward high transmission and backward high reflection film between the glass and the first layer glue film, forward transmissivity of an external interface layer is improved, and sunlight reflected by an internal interface layer returns to a battery piece after repeated reflection, so that the solar cell module with high transmission on a forward direction and high reflection on a backward direction is advantaged by reducing energy loss and improving power generating efficiency.

Description

The reverse high reflected solar energy battery component of the high transmission of forward
Technical field
The utility model relates to the reverse high reflected solar energy battery component of the high transmission of a kind of forward, belongs to solar cell and manufactures field.
Background technology
The general design of crystal silicon solar batteries assembly be by cell piece tandem arrangement between upper and lower two glued membranes, above cover photovoltaic glass lower berth backboard and carry out lamination, thus assembly receive solar radiation be electric energy by light energy conversion.Because light is passing glass and ground floor glued membrane interface, and can there is reflection and transmission phenomenon when second layer glued membrane and cell piece interface simultaneously, thereby make sunlight, some is directly reflected at glass and ground floor glued membrane interface, loss portion of energy, some sunlight is again reflected and then gets back to glass and ground floor glued membrane interface is that transmission is gone out by second layer glued membrane and cell piece interface after transmitted through glass and ground floor glued membrane interface, thereby cause the loss of energy for the second time, the loss of twice energy greatly reduces the generating efficiency of solar module.Therefore seek a kind of energy loss that reduces, the solar module that improves generating efficiency is particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of energy loss that reduces is provided, and improves the solar module of generating efficiency.
The purpose of this utility model is achieved in that
The reverse high reflected solar energy battery component of a kind of high transmission of forward, it comprises glass, ground floor glued membrane, battery strings, second layer glued membrane and backboard, described glass, ground floor glued membrane, battery strings, second layer glued membrane and the backboard lamination of arranging successively from top to bottom, this solar module also comprises the reverse highly reflecting films of the high transmission of forward, and the reverse highly reflecting films of the high transmission of described forward are arranged between glass and ground floor glued membrane.
Preferred as one, it also comprises viscosity glued membrane, and described viscosity glued membrane is arranged between glass and the reverse highly reflecting films of the high transmission of forward.
Preferred as one, the reverse highly reflecting films thickness of the high transmission of described forward is 50 ~ 600 μ m.
Preferred as one, the reverse highly reflecting films thickness of the high transmission of described forward is 100 ~ 400 μ m.
Compared with prior art, the beneficial effects of the utility model are:
The utility model by increasing the reverse highly reflecting films of the high transmission of one deck forward between glass and ground floor glued membrane, increase the forward transmissivity of outer interface layer, and the sunlight of internal interface layer reflection will come back to cell piece through interreflection, make the reverse high reflected solar energy battery component of the high transmission of this forward there is minimizing energy loss, improve the advantage of generating efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the reverse high reflected solar energy battery component of the high transmission of the utility model forward.
Wherein:
Glass 1, ground floor glued membrane 2, battery strings 3, second layer glued membrane 4, backboard 5, the reverse highly reflecting films 6 of the high transmission of forward, viscosity glued membrane 7.
Embodiment
Referring to Fig. 1, the reverse high reflected solar energy battery component of the high transmission of a kind of forward that the utility model relates to, it comprises glass 1, ground floor glued membrane 2, battery strings 3, second layer glued membrane 4 and backboard 5, described glass 1, ground floor glued membrane 2, battery strings 3, second layer glued membrane 4 and backboard 5 lamination of arranging successively from top to bottom, this solar module also comprises the reverse highly reflecting films 6 of the high transmission of forward, and the reverse highly reflecting films 6 of the high transmission of described forward are arranged between glass 1 and ground floor glued membrane 2.Preferred as one, this solar module also comprises viscosity glued membrane 7, and described viscosity glued membrane 7 is arranged between glass 1 and the reverse highly reflecting films 6 of the high transmission of forward.The reverse highly reflecting films 6 of the high transmission of described forward are to cover reflective membrane by the lower surface of base material to form, it is the equal of the principle of microprism, form Unidirectional transparent, described base material is selected PET(PETG, Polythylene terephthalate), also can be POE(polyolefin elastomer) or other high transmission type high polymers, the thickness of the reverse highly reflecting films 6 of the high transmission of described forward is 50 ~ 600 μ m, is preferably 100 ~ 400 μ m.
If the reverse highly reflecting films of the high transmission of forward itself have viscosity, the reverse highly reflecting films of the high transmission of forward are between glass and ground floor glued membrane; If the reverse highly reflecting films of the high transmission of forward itself are inviscid, just need between glass and its, increase one deck viscosity glued membrane and carry out lamination.
The reverse highly reflecting films of the high transmission of forward can be selected microprism, or have light forward full impregnated mistake, and other function films of reverse total reflection function replace.
Generally, the weighting reflectivity of single crystal battery sheet is 6% left and right, and polycrystalline cell piece is 8% left and right.Battery sheet packaging becomes after assembly, between cell piece, and between cell piece and frame, needs to reserve gap, and its effective area of shining light will further reduce.Between the glass of assembly and ground floor glued membrane, increase the reverse highly reflecting films of the high transmission of one deck forward, the sunlight of internal interface layer reflection will come back to cell piece through interreflection, thus increase generating efficiency.
The utility model can be collected cell piece surface and the sunlight being reflected by cell piece gap again, thus can raising efficiency 13% ~ 15% left and right (wherein cell piece interval area account for assembly light-receiving area 7%).In addition, can save cell piece flocking technique, simplify cell piece coating process, thereby reduce costs.
