Photoelectrochromic Devices with Enhanced Power Conversion Efficiency. [PDF]
Materials (Basel), 2020 In the present work, we propose a new architecture for partly covered photoelectrochromic devices with a modified anode layout, so that the TiO2 film is deposited first on the substrate, covering a small part of its surface, followed by the WO3 film that covers the remaining device area. As a result, the TiO2 film can be subjected to the proper thermal
