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

Advances in Power-to-Gas Technologies: Cost and Conversion Efficiency
SSRN Electronic Journal, 2022 This paper examines the cost and efficiency dynamics of three prevalent Power-to-Gas technologies. Our results suggest that electrolytic hydrogen production costs will approach but not reach the U.S. Department of Energy's $1.0/kg target by 2030.

Power conversion efficiency characterization and optimization for smartphones [PDF]
Proceedings of the 2012 ACM/IEEE international symposium on Low power electronics and design, 2012 Modern smartphones consume significant power and can hardly provide a full day's use between charging operations even with a 2000 mAh battery. This is in spite of many power management techniques being employed in the smartphones. This paper starts from the observation that modern smartphones waste a significant amount of the battery's stored energy ...
