Resumé

Thermal stability of the C106 dye in robust electrolytes.
We have investigated the thermal stability and degradation chemistry of the ruthenium dye C106 (Figure 1) at 80 ◦C in the “robust” electrolyte “B” comprised of 1.0 M DMII, 0.03 M I2, 0.5 M NBB, and 0.1 M GuNCS in 3-methoxypropionitrile (3-MPN) introduced by Gao et al. in 2008. [1].
Figure 1 Thermal degradation of C106 bound to TiO2 at 80 ºC in dark as a function of heating time.
● C106 = RuLL´(NCS)2 ■ RuLL´(NCS)(NBB)+ ▲ RuLL´(NCS)(3-MPN)+
The C106 dye was attached to the surface of TiO2 nano-particles and stable colloidal solutions of the particles were prepared in electrolyte mixture B. The solutions were thermally treated at 80 ◦C for 0-2000 hours followed by dye extraction and analysis by HPLC coupled to UV/Vis and electro spray mass spectrometry [2]. Figure 1 shows the concentration profiles of C106 samples prepared under ambient and glove box conditions as a function of the heating time. Preparation of the samples under strict atmospheric moisture control in a glove box gives the best results with a steady state surface concentration of 80% intact C106 and 20% NBB substitution product after ~1500 hours of heating at 80 ºC. If dye degradation was the only loss mechanism in a DSC during thermal treatment the reduction in the DSC efficiency after long term thermal treatment may be estimated to 12%[3]. The dye stability therefore does not seem to be the limiting factor in full filling the requirements of the IEC 1215 standard thermal stress tests.
