1. An electrochromic pane comprising:

  • first and second glass sheets, each coated with a transparent electrically conducting film;

    a first electrode of electrochromic material formed on the first glass sheet;

    a counter-electrode of electrochromic material formed on the second glass sheet;

    an electrolyte formed between the first electrode and the counter-electrode;

    electrical supply leads for connecting the electrically conducting films to an electrical supply system generating a potential difference (U1) as a function of a desired modification of a coloration state of at least one of the first electrode and the counter-electrode; and

    an electron conducting material connecting the electrically conducting films to each other at least at a portion of their periphery for creating a controlled short-circuit between the electrically conducting films, wherein the electron conducting material is filled between the first and second glass sheets by contacting the conducting films.
