Integrated near-field thermo-photovoltaics for on-demand heat recycling
Gaurang R. Bhatt, Bo Zhao, Samantha Roberts +7
The energy transferred via thermal radiation between two surfaces separated by nanometers distances (near-field) can be much larger than the blackbody limit. However, realizing a r…
Axion-Field-Enabled Nonreciprocal Thermal Radiation in Weyl Semimetals
Bo Zhao, Cheng Guo, Christina A. C. Garcia +2
Objects around us constantly emit and absorb thermal radiation. The emission and absorption processes are governed by two fundamental radiative properties: emissivity and absorptiv…
Nonreciprocal radiative heat transfer between two planar bodies
Lingling Fan, Yu Guo, Georgia T. Papadakis +5
We develop an analytical framework for nonreciprocal radiative heat transfer in two-body planar systems. Based on our formalism, we identify effects that are uniquely nonreciprocal…
Broadening near-field emission for performance enhancement in thermophotovoltaics
Georgia T. Papadakis, Siddharth Buddhiraju, Zhexin Zhao +2
The conventional notion for achieving high efficiency in thermophotovoltaics (TPVs) is to use a monochromatic emission at a photon energy corresponding to the band gap of the cell.…
