As the majority of the input energy in power generation or energy consumption processes
goes to waste as heat, thermophotovoltaic (TPV) devices enable energy recovery from …

Titanium nitride (TiN) as a refractory plasmonic material is proposed to be used as an angle-
insensitive integrated broadband solar absorber and narrowband near-infrared (NIR) emitter …

Thermophotovoltaic and rectenna devices can be greatly improved by frequency-selective
emitters, which narrow the emission spectrum of a heat source to couple to the most efficient …
