Experimental Study of Solar Thermophotovoltaic Energy Conversion Enhanced with Selective Metafilm Coatings

A solar thermophotovoltaic (STPV) system requires three key components to directly convert solar energy to electricity: a solar absorber, a hot emitter, and a thermophotovoltaic (TPV) cell. Recently, Prof. Liping Wang’s research group has successfully developed a highly-efficient selective metafilm coating to harvest solar energy from heat. The research has involved experimenting with the metafilm’s

Radiative Cooling of Semiconductive Materials

One challenge facing solar energy is increasing the efficiency of solar cells, which is impeded by the heat they retain. Cooling these cells via emission of radiation in the Infrared (IR) region, using space as a heat sink, allows the temperature within the cells to drop without using electrical energy to cool them. The project

AFM Cantilever Based Near Field Radiation Heat Transfer Measurement

Planck’s theory of blackbody radiation imposes a limit on the maximum radiative transfer between two objects at a given temperature. The objective of the project is to measure the near field radiation between a silica microsphere and a silica substrate, compare it with the theoretical calculations. A custom-designed atomic force microscope (AFM) is being used
