Monochromatic incident illumination photoelectric transformation efficiency (IPCE) describes DSCs photoelectric transformation efficiency under monochromatic light effect, is to turn
Move on to the electron number of external circuit and the ratio of incident illumination subnumber.During measurement, 500 W xenon lamps are used to pass through as light source, incident illumination
The multifunctional assembled grating spectrograph of WDS-5 type obtains the monochromatic light under different wave length λ；Monochromatic light exposure is in the light sun of battery
Pole, is read current value I by Keithley2400 digital sourcemeter.Monochromatic good fortune illumination is micro-by USB4000 plug-and-play
Type light spectral instrument is measured.
Step: in order to have any actual knowledge of dyestuff at TiO2Adsorbance on film, by dye sensitization TiO2Nanometer crystal film (geometric surface
Long-pending about 1 cm2) it is immersed in 10 mL 0.01 mol L-1Sodium hydroxide methanol solution in overnight, treat that dyestuff desorbs completely
The absorbance of rear mensuration solution.Wash one's face and rinse one's mouth according to absorbance and molar absorptivity and can calculate dyestuff on unit are nanometer crystal film
Adsorbance.The adsorbance of this coordination compound is 5.8 × 10-4 mol/cm2。
Result: compared with the methanol solution of dyestuff, dyestuff is at TiO2Absorption spectrum on film the most substantially broadens and red shift.This
Show that dye molecule is at TiO2Define the first and J-aggregation of tail.Say from the operation principle of DSCs, the light that dye aggregation causes
Spectrum width and red shift are highly beneficial for the widening of photoelectric respone scope of dyestuff.But meanwhile, dye aggregation is known from experience
It is substantially reduced its electron injection efficiency, thus causes the degraded performance of DSCs.So, generally add co-adsorption in dye solution
Agent suppresses the gathering of dyestuff.This coordination compound is in methanol solution and at TiO2The fluorometric investigation of the purple solution on membrane electrode is adopted
With 2.5 × 10-5The methanol solution of mol/L, maximum emission wavelength is positioned at 575 nm.
After the preferred embodiment described in detail, it is familiar with this skilled worker and is clearly understood that, without departing from above-mentioned
Can carry out various change and amendment under claim and spirit, all technical spirit according to the present invention are to above example institute
Any simple modification, equivalent variations and the modification made, belongs to the scope of technical solution of the present invention.And the present invention is not illustrated
The restriction of example embodiment in book.
