Abstract

The proposal of the research was used vanadium pentoxide (V₂O₅) as an auxiliary discoloration layer was deposited by magnetron sputtering with different oxygen flow, and the cycle durability and transmittance variation were investigated using a spectrophotometer. An all-solid-state complementary ITO/WO₃/Li-NbO₃/V₂O₅/ITO electrochromic device was all deposited with magnetron sputtering. The results show that V2O5 has the better performance at oxygen flow of 2 sccm for the transmittance variation of ΔT = T_b - T_c =17 %. The cycle area and durability are also better than that of other oxygen flow. However, V₂O₅ and WO₃ has the potential to form an all-solid-state ITO/WO₃/Li-NbO₃/V₂O₅/ITO electrochromic device
