Abstract

The association of polyaniline, PANI, (colored in anodic polarization) and tungsten oxide (colored in cathodic polarization), separated by a solid electrolyte (PAMPS) led to interesting all solid-state electrochromic devices (ASSED). Here, significant improvements are brought to the different ASSED elements, concerning in particular the compositions of the cathodic material and of the solid electrolyte, the pH of which (in the range 0.65 - 7.65) as well as the water content (in the range 0 - 5.2%) are varied. The optimization of the thickness of the PANI layer is discussed. Another crucial point is the choice of the coloration potential (1 V or 1.2 V) allowing to associate a high coloration efficiency with an excellent stability. One knows that the blue colored PANI form appearing at high pH, which is optically the most suited to solar application, with its exciton absorption band at 2 eV, does not allow stable cycling in liquid inorganic electrolyte. On the contrary, with PAMPS, it is possible to use high pH, keeping the reversibility up to 20,000 cycles, probably in reason of the presence of free-carriers at pH as high as 4.5, which also is discussed.
