Thermal and Electrical Study for PV Panel With Cooling
Indonesian Journal of Electrical Engineering and Computer Science, 2017 <p>Paper presents an investigation on photovoltaic (PV) panel with a direct-current (DC) fan cooling system. The DC fan cooling system was installed at the back of PV panel in order to reduce its operating temperature. The performance of PV panel can be affected with the increase of its operating temperature. Therefore, with the aid of the DC fan

Photo‐Switching Thermal and Lithium‐Ion Conductivity in Azobenzene Polymers
Advanced Functional Materials, EarlyView.Light‐responsive azobenzene polymers control thermal and ionic transport simultaneously through structural transitions. UV illumination disrupts π–π stacking, converting crystalline trans states to amorphous cis configurations. Thermal conductivity drops from 0.45 to 0.15 W·m−1·K−1 while Li+ diffusivity increases 100 fold. This dual transport switching
