1. A method for reducing leakage current and enhancing UV stability/in an electrochemichromic cell having spaced plates, each having an inwardly facing conductive surface, and a solution located in said cell between said plates, said solution comprising a redox chemical pair which colors in the presence of an applied voltage and which bleaches to a colorless condition in the absence of an applied voltage said method comprising:

  • using a solvent for said redox chemical pair comprising at least 25% by volume glutaronitrile.
