A new electrodeposition approach for preparing polyoxometalates-based electrochromic smart windows

We explore a new method to prepare polyoxometalate-based electrochromic (EC) smart windows. It is a simple and low cost process to prepare EC films by a solution-based electrodeposition method. The polyoxometalate-based EC smart windows exhibit high transparency in the bleached state, good optical contrast, long durability, and high coloration efficiency.
