For tungsten oxide nano, shell is titanium oxide；Described is FTO substrates, reflective layer, Pt Catalytic Layers from outside to inside to electrode；It is described
Antifreezing agent normal propyl alcohol is added in electrolyte.
Preferably, the preparation process of the dye-sensitized solar cells is as follows：
Step 1 makes FTO substrates：
A) FTO substrates are cleaned：It selects FTO electro-conductive glass as the substrate of light anode, first, cuts FTO electro-conductive glass, use
The conductive one sides of ultra-clean cloth wiping FTO for speckling with liquid detergent, remove the impurity such as greasy dirt, dust existing for surface, then use deionization
Water rinses for several times repeatedly, until liquid detergent is cleaned up, puts it into ozone clean machine, ozone treatment 10min, then according to
It is cleaned by ultrasonic 30min respectively according to the sequence of acetone, ethyl alcohol, deionized water, is dried up with nitrogen gun for use；
B) tungsten oxide nano is grown：The metal of one layer of 150nm thickness is deposited on the surfaces FTO using magnetron sputtering technology
Tungsten film grows source as tungsten oxide nano, while realizing that the localization of tungsten film is grown using ceramic template, in magnetron sputtering process
Ceramic template is attached to the surfaces FTO, wherein the pore diameter of ceramic template is 2 μm, and spacing is 50 μm, magnetron sputtering electric current
For 2A；Tungsten oxide nano growth uses thermal oxidation process, and the FTO electro-conductive glass for being coated with tungsten film is put into thermal evaporation stove,
Under the protection of inert gas, 400 DEG C keep the temperature 5h, are taken out after natural cooling；
C) nucleocapsid tungsten oxide nano is prepared：The ethanol solution for weighing 100ml, is added 1ml's
C16H36O4Ti is stirred evenly under 70 DEG C of water-baths, has the FTO electro-conductive glass of tungsten oxide nano to be put into solution growth,
11s is stood, is then quickly removed, which repeats five times, can ensure that nanowire surface adequately superscribes
Shell structure, then anneal the sample of taking-up at 400 DEG C 1h, carries nucleocapsid tungsten oxide nano after natural cooling to obtain the final product
FTO substrates；
Step 2 adsorbs glass microballoon：
The glass microballoon (Glass Bead Diameter is 5~10 μm) that 20g is bought is taken to be cleaned with deionized water, it is dry, it is added to
It is filtered by vacuum after magnetic agitation 20min in the hydrofluoric acid solution of 20mol/l, it is dry after being cleaned to neutrality with deionized water, it removes
Ionized water 100ml sequentially adds 2.5g sodium citrates, 2.2g ammonium sulfate and 5g nano silver particles, and ammonium hydroxide is then added and adjusts pH
Value is 6, and dry glass microballoon is added in above-mentioned solution, at 60 DEG C, magnetic agitation 2h, and reaction postcooling to room temperature；It will
The FTO substrates with nucleocapsid tungsten oxide nano obtained in step 1 immerse in above-mentioned solution, are stood at 80 DEG C of water-bath
5h, you can form glass microballoon combination nucleocapsid tungsten oxide nano-material in FTO substrate surfaces.
Step 3 is prepared to electrode：
The FTO electro-conductive glass for choosing size identical as light anode, then in one layer of Ag of its surface magnetic control sputtering, as reflective
Layer, Ag thickness are 300nm, and Pt catalyst layers are then deposited again, and Pt catalyst layer thickness is 50nm.
Step 4 assembles dye-sensitized solar cells：
