Abstract:
The invention relates to a process for switching an electrochromic cell (100) comprising at least a first electrode layer (106) and a second electrode layer (108) each capable of reversibly inserting ions. Further the cell (100) comprises an ion-conducting layer (110) that separates the first electrode layer (106) and the second electrode layer (108) and a temperature sensor (216) for measuring a temperature (T) in or on or in the vicinity of the electrochromic cell (100). Moreover, a first contact member (101) is electronically connected with the first electrode layer (106) and a second contact member (102) is electronically connected with the second electrode layer (108), wherein the first (106) and the second electrode layer (108) are counter electrodes to each other. Furthermore, at least said first electrode layer (106) comprises an organic polymer matrix and dispersed within said organic polymer matrix an electrochromic material, electronically conductive nanoobjects (112) and an electrolyte (114) dissolved in a solvent. Further, the process comprises to measure the current (iC) flowing through the cell (100) if a voltage (UC) is applied to the electrode layers (106, 108), and applying a voltage (UC) to contact members (101, 102) and varying the applied voltage (UC) as a function of current (iC), such that the voltage (UC) generated between the electrode layers (106, 108) is kept within predetermined temperature (T) dependent safe redox limits and such that the cell current (iC) is limited to predetermined temperature-dependent limits. Moreover, the applied voltage (UC) is only increased if the cell current (iC) is less than a maximum cell current (imax), determined according to: imax = jmax x Area + (T-T0) x F, where jmax is a predetermined maximum current density, Area is the active cell area, T is the temperature of the electrochromic cell (100) measured with the temperature sensor (216), T0 is a reference temperature, and F a factor. Further, the invention relates to an apparatus (200) and a system (300) for performing the process.
