Description
Technical field
The present invention relates to a kind of solar cell, particularly a kind of high efficiency solar cell that can effectively improve solar battery efficiency.
Background technology
Solar energy is human inexhaustible regenerative resource.Also be clean energy resource, do not produce any environmental pollution.In the middle of effective utilization of solar energy; Big sun can solar photovoltaic utilization be a research field with fastest developing speed in the last few years, most active, is one of project that wherein attracts most attention.
Solar cell is that a pair of light has response also transform light energy can be become the device of electric power, and the material that can produce photovoltaic effect commonly used has many kinds, as: monocrystalline silicon, polysilicon, amorphous silicon, GaAs, selenium indium copper etc., their electricity generating principle is basic identical; With the crystal is example, and P type crystalline silicon can get N type silicon through Doping Phosphorus, forms P-N knot, and when the irradiate light solar cell surface, a part of photon is absorbed by silicon materials; The energy delivery of photon has been given silicon atom, make electronics take place to move more, becoming free electron gathers in P-N knot both sides and has formed potential difference, when circuit is connected in the outside, under the effect of this voltage, flow through the certain power output of external circuit generation with having electric current, this process is exactly the process that photon energy converts electric energy to.
The principle of solar cell is that battery material absorbs certain section wavelength in the sunlight, luminous energy is changed into the device of electric energy.Existing solar cell common used material is a silicon, and monocrystalline silicon, polysilicon etc. are arranged, and for crystal silicon solar energy battery, the light of solar spectrum medium wavelength 0.2～1.25 μ m all can produce photovoltaic effect, and at different materials, the corresponding scope of spectrum is also different.The efficient of monocrystaline silicon solar cell is 15%～20% at present, and the efficient of polysilicon solar cell is about 15%.
Obviously, the efficient of existing solar cell is lower, and is traditional, in order to improve solar battery efficiency, all be composition, though efficient increases by continuous modification material, but all be subjected to the restriction of sunlight wave band, make the efficient raising of solar cell run into bottleneck; Therefore, need a kind of high efficiency solar cell that can effectively raise the efficiency especially.
Summary of the invention
The purpose of this invention is to provide a kind of high efficiency solar cell, under the prerequisite of existing heliotechnics, do not change the material and the production technology of existing solar cell, can on the basis of original solar cell device, improve the efficient of solar cell.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of high efficiency solar cell, it comprises solar panel, it is characterized in that, is provided with phosphor layer on the surface of described solar panel.
Described phosphor layer is evenly distributed by fluorescent material and forms.
By the binding agent bonding, can also smear, be printed in top layer or other multiple modes between described phosphor layer and the described solar panel.
Described phosphor layer is arranged on the interior surface of described solar panel.
The principle of high efficiency solar cell of the present invention is as follows:
By the non-constant width of the spectrum of sunlight, there is quite a few spectrum to be absorbed by solar cell, cause solar battery efficiency to be restricted, can not be transformed into by the sunlight optical band that solar cell absorbs can be by the optical band of solar absorption, thereby improves the efficient of solar cell.
High efficiency solar cell of the present invention by on the solar panel surface phosphor layer being set, changes the optical band of the absorption of solar panel, thereby effectively improves the efficient of solar cell, realizes purpose of the present invention.

Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 2, a kind of high efficiency solar cell, it comprises solar panel 1, is provided with phosphor layer 2 on the surface of described solar panel 1.
Described phosphor layer 2 is evenly distributed by fluorescent material and forms, and by the binding agent bonding, can also smear, be printed in top layer or other multiple modes between described phosphor layer 2 and the described solar panel 1.
Equally, described phosphor layer 2 also can be arranged on the interior surface of described solar panel 1.
As shown in Figure 1, the wave band of solar energy maximum is at 650nm-680nm, and the best transition wavelength of solar cell is about 1000nm, and as shown in Figure 1, the solar energy of 1000nm proportion in whole solar energy zone is very little.
Referring to Fig. 2, the sunlight of the sun 3 emissions incides phosphor layer 2, part sunlight directly enters solar panel 1, another part sunlight then passes through phosphor layer 2, after being changed, the sunlight wavelength of process phosphor layer 2 enters solar panel 1 again, solar panel 1 absorbs required optical wavelength, thereby transform light energy is become electric energy.
As shown in Figure 3, Figure 4, sunlight changes sunlight wavelength through behind the phosphor layer 2 to the available wave band of solar cell zone, the spectrum of sunlight is offset to long-wave band, the energy of the required wavelength period of solar cell improves (referring to Fig. 4), thereby improves solar battery efficiency.
High efficiency solar cell of the present invention is provided with phosphor layer 2 by the surface at solar panel 1 and has abolished this bottleneck that existing solar battery efficiency improves, only need on original solar cell basis, increasing phosphor layer 2 can change the sunlight wave band to the required wave band of solar cell, thereby overcome the restriction that the sunlight spectral power distribution is produced, thereby improve solar battery efficiency.
Equally, the shape of the solar panel 1 among the present invention can be different shapes such as plate shaped, waveform, fluorescent material in the described phosphor layer 2 also can be black, etc. other colors, help the further absorption of 1 pair of sunlight of solar panel, these do not influence the present invention and realize its goal of the invention.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof.
