Abstract
▶ Present paper demonstrate the electrochromic properties (EC) of NiO thin films of different thickness with change in deposition time by a simple and cost effective chemical bath deposition method. ▶ Nanoporous NiO thin films were investigated as a function of film thickness in both aqueous (KOH) and non aqueous (LiClO4-PC) electrolyte. ▶ The increment in the transmittance modulations with increase in film thickness leads to an increase in coloration efficiency (CE) to about 95 cm2/C, which is two times more than that observed in KOH with excellent electrochemical stability upto 3000 c/b cycles in LiClO4-PC electrolyte. ▶ This suggest that electrochromic properties of the NiO films can be tailored merely by controlling the film thickness and choice of suitable electrolyte which will be potentially useful for designing complementary EC devices.
