D. Ti substrate obtained above is processed 1 hour at 150 DEG C, be then immersed in rapidly in the ethanolic solution of 0.46mMN719, 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 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.
