Abstract
Electrochromic module including first and second substrates is provided in which the first and/or second substrate are/is electrically conductive or are/is equipped with an electrically conductive coating. A first electrochromic polymer coating is arranged on the first substrate or the conductive coating, an ion-storage or charge-compensating layer is arranged on the second substrate or the conductive coating, and a polymer gel electrolyte is disposed between the electrochromic coating and the ion-storage or charge-compensating layer. The electrochromic polymer, a polymer of tetraarylbenzidine and (hetero)aromatic diol, is colorless in one redox state and colored in at least two redox states. The ion-storage or charge-compensating layer is formed from material selected from the group comprising cerium oxide, titanium oxide, tungsten oxide, nickel oxide, molybdenum oxide, vanadium oxide and mixtures thereof or redox-active polymer. The inventive modules achieve a large number of switching cycles, a high electrochromic contrast and a high electrochromic efficiency.
