Photoelectrochromic Devices with Enhanced Power Conversion Efficiency. [PDF]

open access: yesMaterials (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

Multi-channel nanowire devices for efficient power conversion [PDF]

open access: yesNature Electronics, 2021
Nanowire-based devices can potentially be of use in a variety of electronic applications, from ultrascaled digital circuits to 5G communication networks. However, the devices are typically restricted to low-power applications due to the relatively low electrical conductivity and limited voltage capability of the nanowires.
