The performance characteristics of WO3 electrochemichromic cells have been studied in connection with the electrical resistance of transparent electrodes and a lumped resistor connected to the electrodes in series. The sheet resistance of transparent electrodes used and the resistance of lumped resistor used are in the range of 10–1250 Ω/[Laplacian_variant] and 10–2500 Ω, respectively. The thickness of the WO3 film is ∼2400 Å or ∼4300 Å, and the electrolyte is 1 N H2SO4 aqueous solution containing 10 vol % glycerol. The current pulse form and the change in optical transmittance of experimental cells under operation were observed, and the operating characteristics of electrochemichromic cells have been found to clearly depend on the sheet resistance of transparent electrodes and/or the resistance of a lumped resistor connected serially.
