Abstract

The invention provides a solar cell comprising a junction box, a plasma layer, silica gel, and a backplane. The plasma layer is arranged between the junction box and the silica gel. The junction box is connected with the backplane through the silica gel. The backplane comprises a PVF film layer, a PET film layer, and an efficiency-increasing film layer which are successively arranged from top to bottom, wherein the efficiency-increasing film layer is used for absorbing ultraviolet light from 10 to 400nm. The PVF film layer, the PET film layer, and the efficiency-increasing film layer are formed by co-extrusion. The junction box of the solar cell is more firmly combined with the backplane and the solar cell has a high photoelectric conversion rate.

Description

A kind of solar cell
Technical field
The present invention relates to technical field of solar, particularly a kind of solar cell.
Background technology
In recent years, environmental pollution has caused global concern, and the greenhouse effect caused by the carbon dioxide especially discharged by mineral matter fuel combustion are a serious problem especially.Therefore, people wish to develop non-polluting energy sources strongly.As novel energy, can there is inexhaustible, nexhaustible, pollution-free, non-harmful feature and enjoy global concern, and realizing the industrialization of energy conversion very much.At present, one of people's Main Means utilizing solar energy is, utilizes solar cell to carry out photoelectric conversion to solar energy, solar energy is changed into electric energy.
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.
Summary of the invention
In view of this, the object of this invention is to provide a kind of terminal box and be combined with backboard more firm, and the solar cell that optoelectronic transformation efficiency is high.
The invention provides a kind of solar cell, comprise terminal box, plasmasphere, silica gel and backboard, 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 PVF rete, PET film layer and the synergy rete for the ultraviolet light that absorbs 10-400nm that set gradually from top to bottom, described PVF rete, described PET film layer and described synergy rete coextrusion mold.
Further, the thickness of described PVF rete is 15-45um.
Further, the thickness of described PET film layer is 100-400um.
Further, the thickness of described synergy rete is 15-150um.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The terminal box of solar cell of the present invention is combined more firm with backboard, and optoelectronic transformation efficiency is high.
Accompanying drawing explanation
Fig. 1 be the embodiment of the present invention too can the structural representation of battery.
Fig. 2 is the structural representation of the backboard in Fig. 1.
