Abstract: Described herein is a process for switching an electrochromic cell including at least a first electrode layer and a second electrode layer. The cell also includes an ion-conducting layer that separates the first and second electrode layers and a temperature sensor for measuring a temperature in or on or in the vicinity of the electrochromic cell. Moreover, a first contact member is electronically connected with the first electrode layer, and a second contact member is electronically connected with the second electrode layer. Furthermore, at least the first electrode layer includes an organic polymer matrix and, dispersed therein, an electrochromic material, electronically conductive nanoobjects, and an electrolyte dissolved in a solvent. Further, the process including measuring the current flowing through the cell if a voltage is applied to the electrode layers, applying a voltage to the contact members, and varying the applied voltage as a function of the current.

Abstract: Described are electrochromic devices and compositions as well as manufacturing methods for making such electrochromic devices by printing or wet processing of the compositions. The compositions are in the form of a suspension and comprise two or more monomers, nanoparticles of an electrochromic metal oxide, one or more metal salts of the form (M)z(R)y, where M is a metal cation and R is the corresponding salt anion, a carrier liquid and a solvent. The compositions are polymerised to form a composite layer comprising a polymer matrix that hosts the electrochromic nanoparticles and the electrolyte. At least a part of the metal salts (e.g. zinc acetate) is physically adsorbed onto the surface of the nanoparticles and acts as a dispersant.
