The concrete instance that dyestuff or luminous agent use
Method: the PARSTAT2273 electrochemical workstation of differentiated pulse volt-ampere (DPV) the curve negotiating Princeton Applied Research Laboratory development of dye solution is measured.The DPV test of solution adopts three-electrode system, and glass-carbon electrode is working electrode, and supporting electrode is platinum plate electrode, homemade Ag/AgNO
3electrode is reference electrode; Electrolytic solution is the acetonitrile solution of 0.1molL-1TBAP.Reduce reversible point to for interior mark with Oxidation of Ferrocene, obtains the correction value between test system and standard hydrogen electrode system.
Monochromatic incident light photoelectric transformation efficiency (IPCE) describes the photoelectric transformation efficiency of DSCs under monochromatic ray effect, is transfer to the electronic number of external circuit and the ratio of incident light subnumber.During measurement, use 500W xenon lamp as light source, the monochromatic ray of incident light under the multifunctional assembled grating spectrograph of WDS-5 type obtains different wave length λ; Monochromatic light exposure, in the light anode of battery, reads current value I by Keithley2400 digital sourcemeter.Monochromatic good fortune illumination is measured by USB4000plug-and-play Miniature optical linear light spectrometer.
Step: in order to definitely understand dyestuff at TiO
2adsorptive capacity on film, complex monocrystal dye sensitization TiO prepared by embodiment 2
2(geometric area is about 1cm to nanometer crystal film
2) be immersed in 10mL0.01molL
-1sodium hydroxide methanol solution in spend the night, treat that the absorbancy of attached mensuration solution separated completely by dyestuff.Wash one's face and rinse one's mouth according to absorbancy and molar absorptivity and can calculate the adsorptive capacity of dyestuff on unit surface nanometer crystal film.The adsorptive capacity of this complex monocrystal is 1.4 × 10
-3mol/cm
2.
Result: compared with the methanol solution of dyestuff, complex monocrystal dyestuff is at TiO
2absorption spectrum on film all obviously broadens and red shift.This shows that dye molecule is at TiO
2define the J-aggregate of first also tail.From the principle of work of DSCs, the spectrum broadening that dye aggregation causes and red shift are very favourable for the widening of photoelectric response scope of dyestuff.But meanwhile, dye aggregation cognition reduces its electron injection efficiency greatly, thus causes the degraded performance of DSCs.So, in dye solution, usually add coadsorbent to suppress the gathering of dyestuff.This complex monocrystal is in methanol solution and at TiO
2the fluorometric investigation of the purple solution on membrane electrode adopts 2.5 × 10
-5the methanol solution of mol/L, maximum emission wavelength is positioned at 500nm.
