METHOD AND SYSTEM FOR LOWERING THE DRIVE POTENTIAL OF AN ELECTROCHROMIC DEVICE

摘要

An electrochromic (EC) device (100) having a low starting potential, thereby- having a lower drive potential is disclosed. The device comprises a first electrode (175) covered with a metal oxide (160) and a nanoporous nanocrystalline film (170), a second electrode (180) covered with a metal oxide layer (190), a viologen electrochromic layer (172) and an electrolyte (140) disposed between the electrodes (175, 180). A potential is applied to the EC device to lower the starting potential. Methods and systems for manufacturing EC devices and adjusting the drive potential of an existing EC device are also disclosed.
