Solar cells are a renewable energy technology that has begun to supply energy in many regions of the world at a utility scale. Nonetheless, further improvements in solar technology are still needed to help reduce costs and increase adoption. Many researchers have been particularly interested in...
RadCool: a Web-enabled Simulation Tool for Radiative Cooling
14 Aug 2017 | Presentation Materials | Contributor(s): Yu-wen (Wendy) Lin, Evan L Schlenker, Zhou Zhiguang, Peter Bermel
Thermophotovoltaic (TPV) systems can generate electricity from high-temperature heat sources via thermal radiation. However, the intense heating of a photovoltaic (PV) cell can greatly reduce the overall efficiency of the system. Therefore, it is critical to develop techniques to keep the PV...
