Anode, electrode and electrolyte are constituted；The structure of described smooth anode is FTO substrate from outside to inside, is grown on FTO substrate surface
Tungsten oxide nano, be coated on the glass microballoon bottom tungsten oxide nano；Described tungsten oxide nano is nucleocapsid structure, core
For tungsten oxide nano, shell is titanium oxide；Described is FTO substrate from outside to inside, reflector layer, Pt Catalytic Layer to electrode；Described
Electrolyte adds antifreezing agent normal propyl alcohol.
Preferably, the preparation process of described dye-sensitized solar cells is as follows:
Step one, making FTO substrate:
A) FTO substrate is cleaned: select FTO electro-conductive glass as the substrate of light anode, first, cut FTO electro-conductive glass, use
Speckle with the ultra-clean cloth wiping FTO conduction one side of liquid detergent, remove the impurity such as the greasy dirt of surface existence, dust, then use deionization
Water rinses for several times repeatedly, until being cleaned up by liquid detergent, puts it in ozone clean machine, and ozone processes 10min, then depends on
According to the order ultrasonic cleaning 30min respectively of acetone, ethanol, deionized water, dry up stand-by by nitrogen gun；
B) growth tungsten oxide nano: use magnetron sputtering technology to be deposited with the thick metal of one layer of 150nm on FTO surface
Tungsten film, as tungsten oxide nano growth source, uses pottery template to realize the localization growth of tungsten film, in magnetron sputtering process simultaneously
Pottery template is attached to FTO surface, and wherein, the pore diameter of pottery template is 2 μm, and spacing is 50 μm, magnetron sputtering electric current
For 2A；Tungsten oxide nano growth uses thermal oxidation process, puts in thermal evaporation stove by the FTO electro-conductive glass being coated with tungsten film,
Under the protection of noble gas, 400 DEG C of insulation 5h, take out after natural cooling；
C) prepare nucleocapsid structure tungsten oxide nano: weigh the ethanol solution of 100ml, add 1ml's
C16H36O4Ti, stirs under 70 DEG C of water-baths, and growth has the FTO electro-conductive glass of tungsten oxide nano put in solution,
Standing 11s, then quickly remove, this immersion solution processes repeats five times, ensure that nanowire surface sufficiently superscribes
Shell structure, then by the sample taken out at 400 DEG C of 1h that anneal, i.e. obtains with nucleocapsid structure tungsten oxide nano after natural cooling
FTO substrate；
Step 2, absorption glass microballoon:
Take glass microballoon (Glass Bead Diameter is 5～10 μm) the deionized water cleaning that 20g buys, be dried, join
Magnetic agitation 20min final vacuum sucking filtration in the hydrofluoric acid solution of 20mol/l, cleans with deionized water and is dried to neutrality, remove
Ionized water 100ml, is sequentially added into 2.5g sodium citrate, 2.2g ammonium sulfate and 5g nano silver particles, is subsequently added ammonia regulation pH
Value is 6, is added by dry glass microballoon in above-mentioned solution, at 60 DEG C, and magnetic agitation 2h, it is cooled to room temperature after reaction；Will
The FTO substrate with nucleocapsid structure tungsten oxide nano obtained in step one is immersed in above-mentioned solution, stands at water-bath 80 DEG C
5h, can form glass microballoon syncaryon shell structure tungsten oxide nano-material at FTO substrate surface.
Step 3, preparation is to electrode:
Choose and the FTO electro-conductive glass of light anode same size, then at one layer of Ag of its surface magnetic control sputtering, as reflective
Layer, Ag thickness is 300nm, is deposited with Pt catalyst layer the most again, and Pt catalyst layer thickness is 50nm.
Step 4, assembling dye-sensitized solar cells:
Iodine/iodine three anion electrolyte that electrolyte application is traditional: first weigh the acetonitrile solution of 100ml, add wherein
Enter the lithium iodide of 0.1M, 0.1M iodine, 0.6M 4-tert .-butylpyridine and the tetrabutylammonium iodide of 0.6M, the ultrasonic 5min of lucifuge,
Make it fully dissolve, then weigh the nano TiO 2 nanoparticle of 8g, under water-bath 70 degrees Celsius, TiO2 nanoparticle is added
In electrolyte solution, it is eventually adding 5ml antifreezing agent normal propyl alcohol, ultrasonic 30min so that it is be sufficiently mixed uniformly；
Dye solution: weigh N719 powder 50mg, dehydrated alcohol 30ml, N719 is added in dehydrated alcohol, fully dissolve,
Lucifuge stirring 12h.The dye solution taking above-mentioned preparation is put in brown glass ware, then FTO substrate is entered this brown glass
In ware, lucifuge is sensitization 3h at 60 DEG C, takes out, is then packaged together electrode with this light anode, and encapsulating material uses heat-sealing
