The structure stating light anode is FTO substrate from outside to inside, is grown on the tungsten oxide of FTO substrate surface
Nano wire, it is coated on the glass microballoon bottom tungsten oxide nano；Described tungsten oxide nano is nucleocapsid
Structure, core is tungsten oxide nano, and shell is titanium oxide；Described is FTO from outside to inside to electrode
Substrate, reflector layer, Pt Catalytic Layer；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
Cut FTO electro-conductive glass, with speckling with the ultra-clean cloth wiping FTO conduction of liquid detergent simultaneously, remove surface
The impurity such as the greasy dirt of existence, dust, then rinse for several times repeatedly with deionized water, until by liquid detergent
Cleaning up, put it in ozone clean machine, ozone processes 10min, then according to acetone, second
Alcohol, the order ultrasonic cleaning 30min respectively of deionized water, dry up stand-by by nitrogen gun；
B) growth tungsten oxide nano: use magnetron sputtering technology to be deposited with a layer on FTO surface
Metal tungsten film thick for 150nm, as tungsten oxide nano growth source, uses pottery template to realize tungsten simultaneously
The localization growth of film, is attached to FTO surface, wherein, pottery by pottery template in magnetron sputtering process
The pore diameter of ceramic former plate is 2 μm, and spacing is 50 μm, and magnetron sputtering electric current is 2A；Tungsten oxide
Nanowire growth uses thermal oxidation process, and the FTO electro-conductive glass being coated with tungsten film is put into thermal evaporation stove
In, 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
The C16H36O4Ti of 1ml, stirs under 70 DEG C of water-baths, growth is had tungsten oxide nano
FTO electro-conductive glass is put in solution, stands 11s, then quickly removes, this immersion solution processes weight
Multiple five times, ensure that nanowire surface sufficiently superscribes shell structure, the sample that then will take out
At 400 DEG C of 1h that anneal, after natural cooling, i.e. obtain the FTO base with nucleocapsid structure tungsten oxide nano
The end；
Step 2, absorption glass microballoon:
Take glass microballoon (Glass Bead Diameter is 5～10 μm) the deionized water cleaning that 20g buys,
It is dried, joins magnetic agitation 20min final vacuum sucking filtration in the hydrofluoric acid solution of 20mol/l, spend
Ionized water cleans and is dried to after neutrality, removes ionized water 100ml, be sequentially added into 2.5g sodium citrate,
2.2g ammonium sulfate and 5g nano silver particles, being subsequently added ammonia regulation pH value is 6, by dry glass
Glass microballon adds in above-mentioned solution, at 60 DEG C, and magnetic agitation 2h, it is cooled to room temperature after reaction；
Above-mentioned solution is immersed in the FTO substrate with nucleocapsid structure tungsten oxide nano obtained in step one
In, stand 5h at water-bath 80 DEG C, glass microballoon can be formed at FTO substrate surface and combine nucleocapsid knot
Structure tungsten oxide nano-material.
Step 3, preparation is to electrode:
Choose and the FTO electro-conductive glass of light anode same size, then at its surface magnetic control sputtering one
Layer Ag, as reflector layer, Ag thickness is 200nm, is deposited with Pt catalyst layer the most again, and Pt urges
