| Abstract Scope |
Research focuses on harvesting photoenergy through direct and indirect methods for a sustainable energy cycle. Systems like photovoltaics and photoelectrochemical devices face challenges such as energy losses and high implementation costs. The "photo-battery" combines energy harvesting and storage in one electrode system, offering an innovative solution. The integration of nanostructures as dual-action materials opens up many possibilities for optimizing battery performance. Different shapes and compositions can be tailored for maximum efficiency, utilizing morphology-related advantages. Precisely tuning particle dimensions can further improve functionality. This talk focuses on the fabrication of TiO<sub>x</sub>-/ V<sub>2</sub>O<sub>5</sub>- nanofibers as composite materials and their implementation in photo-rechargeable batteries. Functionalization improved charge separation and light absorption, while also enhancing material stability and maintaining its capacity over 300 cycles. To achieve this, modern techniques like electrospinning and plasma-enhanced chemical vapor deposition (PE-CVD) are used to functionalize the materials and tune their properties in a targeted, beneficial manner |
