Existingly can generally comprise terminal box and backboard by battery very much, silica gel is adopted to be connected between terminal box with backboard, in process of production, inevitably the surface that contacts with silica gel of terminal box is unclean, and because terminal box is that plastics material is made, the face that terminal box contacts with silica gel is comparatively level and smooth, causes the caking ability of terminal box and silica gel inadequate, thus it is firm not to make terminal box be combined with backboard, terminal box easily comes off.
In addition, current commercialization crystal silicon solar energy battery dominant absorption utilizes the visible ray of 400-700nm, light for the ultra-violet bands lower than 400nm does not absorb substantially, the energy of part sunlight is caused not to be used effectively, this have impact on the efficiency of solar cell to a certain extent, make the efficiency of Current commercial crystal silicon solar energy battery substantially be in 14%-17%, under the level of production of existing commercialization crystalline silicon, difficulty has and improves greatly.Therefore, the optoelectronic transformation efficiency of solar cell of the prior art is low.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of terminal box and is combined with backboard more firm, and the solar cell that optoelectronic transformation efficiency is high.
The utility model provides a kind of solar cell, comprises terminal box, plasmasphere, silica gel and backboard, and wherein, described plasmasphere is arranged between described terminal box and described silica gel, and described terminal box is connected with described backboard by described silica gel; Described backboard comprises the pvdf membrane layer, PET film layer, tack coat and the synergy rete for the ultraviolet light that absorbs 10-400nm that set gradually from top to bottom, described pvdf membrane layer and PET film layer coextrusion mold, the two sides of described tack coat is closed with described PET film layer and described synergistic film laminating respectively.
Further, the thickness of described pvdf membrane layer is 10-40um.
Further, the thickness of described PET film layer is 100-400um.
Further, the thickness of described tack coat is 5-30um.
Further, the thickness of described synergy rete is 15-150um.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The terminal box of solar cell of the present utility model is combined more firm with backboard, and optoelectronic transformation efficiency is high.
Accompanying drawing explanation
Fig. 1 be the utility model embodiment too can the structural representation of battery.
