Fig. 2: Schematic diagrams of device configurations and working principles of PSCs-powered ECS.
From: Automatic light-adjusting electrochromic device powered by perovskite solar cell
Perovskite solar cell (left) harvests solar energy to drive ECD/ECS (middle) to different colored states under different light intensities, and the stored energy of ECS (in deep colored state) can light a red LED (right).
