Alternative plasmonic materials can withstand extreme temperatures, opening new frontiers in energy‐harvesting applications. A metamaterial based on titanium nitride, described by J. G. Guan, A. V. Kildishev, and co‐workers on page 7959, efficiently converts sunlight into heat, achieving temperatures greater than 1000 °C and it re‐radiates this energy in a narrow bandwidth for optimal absorption by a photocell. The near perfect absorption of the metasurface coupled with its thermal stability enables practical next generation solar thermo‐photovoltaic devices.
