Preferably, the solar panel is dye-sensitized solar cells, at this stage, to dye sensitization of solar
The improvement of nanometer material structure in battery light anode is a kind of important hand improving dye-sensitized solar cells opto-electronic conversion
Section.The photoelectric conversion efficiency of the factors such as specific surface area, electronic transmission performance and the light scattering property of light anode structure and battery
There is prodigious relationship, the rational design to light anode structure can make battery have outstanding photoelectric conversion efficiency.
Dye-sensitized solar cells of the present invention includes light anode, specifically, the light anode include Zn pieces substrate,
ZnO nano-wire film set on Zn piece substrate surfaces and the TiO on ZnO nano-wire film2Laminated film.Using
The advantages of this structure is so that solar energy is deep enough to Zn pieces substrate and cannot penetrate, and then sunlight can be through light sun

It receives, utilize, unexpected advantageous effect is played for the raising of photoelectric conversion efficiency.The technical solution of present embodiment,
On traditional light anode architecture basics, using Zn pieces as substrate, Zn pieces are opaque, therefore, will be to electrode towards sunlight when installation
Irradiation one side, in this way, sunlight can be penetrated to electrode.In the art, it is common practice to which light anode uses FTO substrates
And TiO2The configuration of nano thin-film, and this programme is using Zn pieces, ZnO nano-wire film, TiO2The construction of laminated film, this and biography
The light anode tool of system is very different：One is, supporting body of the Zn pieces as ZnO nano-wire film, with ZnO nano-wire it
Between resistivity it is smaller, be conducive to the transmission of electronics.Or be, on the one hand ZnO nano-wire film can provide electron-transport
Channel, on the other hand, ZnO nano-wire film have big specific surface area, enable to TiO thereon2Laminated film and dye
Material infiltration wherein, increases dyestuff and TiO2The adsorption area of laminated film.
In the light anode of the present invention, which is derived from purchase, and Zn piece purity is 99.5% or more, before use, needing to it
It cut, cleaned, cleaning uses customary means in this field.Then, it is grown on Zn pieces surface using hydro-thermal method
ZnO nano-wire film：Configure mixed solution, wherein in mixed solution containing 0.04mol zinc acetates, 0.06mol ethylene glycol amines and
100ml absolute ethyl alcohols, by mixed solution magnetic agitation 30min at room temperature, after mixed solution is put into 70 DEG C of oil bath pan,
Magnetic agitation 12h obtains ZnO seed layer solution；Then Zn pieces are slowly immersed in ZnO seed layer solution, stand 20s, slowly
It pulls out, holding pull rate is 0.05cm/s, and the Zn pieces lifted out are placed in 60 DEG C of baking oven and are dried, then put Zn pieces
Enter 450 DEG C of annealing 2h of Muffle furnace high temperature, wherein the heating-up time that Muffle furnace increases the temperature to 450 DEG C is 60min so that Zn
Piece surface is covered with layer of ZnO seed layer；Configuration contains 40mmol Zn (NO3)2·6H2O, 40mmol hexamethylenetetramines and
The mixed solution of 40mmol deionized waters, then into mixed solution be added 1ml ammonium hydroxide, ammoniacal liquor mass concentration 30.48%,
After stirring 3h, mixed solution is transferred in autoclave liner；Then the above-mentioned Zn pieces for being covered with ZnO seed layers are immersed into autoclave
In the mixed solution of liner, after sealing, autoclave is placed in 90 DEG C of environment, reacts 28h, natural cooling drops after the completion of reaction
Temperature takes out Zn pieces, spends example water and cleans 3 times, and obtaining growth has the Zn pieces of ZnO nano-wire film.
By above-mentioned steps, the length of ZnO nano-wire is 15 μm, a diameter of 120-150nm of ZnO nano-wire, nano wire
Density is about 5.6 × 108Root/m2.In the present solution, by substrate and TiO2Nano wire film is set between laminated film, is generated
