Thermal Management System for Solar Photovoltaic Installations
2019-185 – For all commercial photovoltaic (PV) solar panels, the performance of these devices decreases as the operating temperature is increased above 25 °C. In the sunny, dry climates that are ideal for PV installations, the average operating temperature of the panels is ~49 °C and their performance suffers accordingly. Presently, the common practice for megawatt-scale PV arrays in the United... Read More
Porous Material for Continuous Radiative Cooling
7417 – Passive radiation of heat is an energy efficient approach to cooling that requires no moving parts or power consumption. However, most state-of-the-art approaches cannot cool the object below the temperature of its surroundings, which is often insufficient. A relatively new approach utilizes materials that radiatively reject heat to Space (effectively at 3 K) by selectively emitting... Read More
Thin Multi-Layer Cell Structures for High-Performance Thermophotovoltaics
2018-355 – Thermophotovoltaic (TPV) energy conversion refers to a process in which thermal energy is converted to electrical energy. Compared to conventional photovoltaic solar panels, TPV panels have the potential for significantly higher energy densities and should be able to provide comparable output power while using significantly smaller footprints. TPV devices consist of a thermal emitter... Read More
