摘要：

Electrochromic cells in a proposed new architecture, called unbalanced configuration, were constructed using poly(2,2-dimethyl-3,4 propylenedioxythiophene) (PolyPRODOT-Me-2) as the working electrode and tungsten trioxide (WO3) as the counter electrode. This unbalanced system allowed us to drastically change the electrochromic behavior of WO3, using it as an optically-passive transparent material, therefore confirming the potential of this new configuration as a viable alternative in the design of electrochromic devices. Functional electrochromic cells working under a narrow voltage of 1.5 V and reaching an optical contrast of 52% at 566 nm were constructed and tested. (C) 2016 Elsevier B.V. All rights reserved.
