Novel photoelectrochromic devices incorporating carbon-based perovskite solar cells

In the present work, we propose for the first time, the use of a carbon-based perovskite solar cell (PSC) in a “partly covered” photoelectrochromic (PEC) device, with a three-electrode architecture that de-couples the photovoltaic (PV) and electrochromic (EC) operation, thus enabling better control of the device optical modulation. The proposed configuration also permits solar power production when the EC window remains idle at a given...
