Modeling Efficiency of InAs-Based Near-Field Thermophotovoltaic Devices

Enormous potential lies in waste-heat recycling for the world’s industrial sector. Portable solid-state modules are a universal low-maintenance method to recycle this waste-heat. One such technology, near-field thermophotovoltaics (NFTPV), relies on a heat source in extreme proximity (<200 nm) to a photovoltaic cell, which then generates electricity. We developed an optoelectronic model where electron-hole pair generation rates are calculated...
