2be distributed in the mixed liquor of hydrochloric acid and ethanol with NiO mixing small-particle, volume ratio 1:4, after fully stirring, obtain nanometre glue; Then a certain amount of P25 (containing 70% anatase, 30% rutile) is distributed in absolute ethyl alcohol, obtains the P25 suspension of solid content 25wt%; Joined by nanometre glue in P25 suspension, fully stir the P25 slurry obtained containing mixing small-particle, finally employing is scraped the skill in using a kitchen knife in cookery and is coated in by slurry in Ti substrate;
C. by a certain amount of tetrabutyl titanate (TBOT), and a certain amount of P25 is (containing 70% anatase, 30% rutile) in closed container, stir 10h with 6ml absolute ethyl alcohol, obtain the P25 slurry containing TBOT, and then adopt and scrape the skill in using a kitchen knife in cookery by this slurry blade coating on Ti sheet;
The mass ratio of described slurry TBOT and P25 is 0.3-0.5;
D. Ti substrate obtained above is processed 1 hour at 150 DEG C, be then immersed in rapidly in the ethanolic solution of 0.4mMN719, leave standstill 12 hours, N719 sensitization flexible working electrode namely;
(3) preparation is to electrode
Adopt conductive plastics (ITO-PET) to electrode, get the ITO-PET with Ti substrate same size, adopt magnetron sputtering one deck Pt electrode, Pt thickness is 1.43 μm;
Further, before sputtering Pt electrode, cellulase treatment can be carried out to conductive plastics:
Remove on-chip various greasy dirt thing, put into compound biological enzyme liquid successively, each ultrasonic 15min of deionized water; Then dry;
The composition of described compound biological enzyme is: alkali protease, cellulase, polyphenol oxidase, and all the other are deionized water;
(4) device assembling
By above work electrode with electrode clip is stepped up, to the liquid electrolyte of space injection therebetween, the flexible sensitization solar battery of sandwich structure consisting, wherein, electrolyte components is 0.5MLiI+0.05MI2+0.1M4-butyl-pyridinium, and solvent is acetonitrile and the propylene carbonate mixed liquor of volume ratio 1:1.
