Abstract
This presentation presents a near-field thermophotovoltaic (TPV) system using undoped silicon emitters with nanoscale gaps measured by spectroscopy and microscopy techniques. The system significantly enhances radiative transfer over the far-field limit in a scalable design using standard microfabrication methods. Our robust design, tested under high temperatures, demonstrates the potential for efficient and power-dense TPV systems for converting heat into electrical energy.
