A Review on Monolithic All-Solid-State Inorganic Electrochromic Smart Window

In this review, research and development trends of monolithic all-solid inorganic electrochromic smart windows were introduced. Due to global warming, an electrochromic smart window which is effective for energy saving has been gaining a lot of attention. However, high production cost and durability issues are limiting its widespread use. Various studies have been conducted on counter electrode and electrolyte materials to improve electrochromic performance and durability as well as productivity. In addition, research on optimizing the device structure through the passivation layer and on film-type electrochromic devices using flexible substrates have also been conducted. These recent research results are expected to enable the global distribution of smart windows.
