Thermophotovoltaic system and method of making the same

A system comprising:

• a first cylindrical structure embedded into a second cylindrical structure, wherein the first cylindrical structure comprises:
• a chamber, wherein the chamber comprises an isotope;
• and
• a plurality of plasmonic materials on an outer wall of the first cylindrical structure;
• wherein the second cylindrical structure comprises:
• a plurality of photovoltaic cells on an inner wall of the second cylindrical structure,
• wherein a radius of the second cylindrical structure is greater than a radius of the first cylindrical structure.

A method of using a thermophotovoltaic system comprising:

• reacting a chemical in a chamber of a first cylindrical structure, wherein the first cylindrical structure comprises the chamber;
• radiating heat from the chamber onto a plurality of plasmonic materials, wherein the plurality of plasmonic materials are on an outer wall of the first cylindrical structure;
• emitting a wavelength from the plurality of plasmonic materials onto a plurality of photovoltaic cells, wherein a second cylindrical structure comprises the plurality of photovoltaic cells, wherein the first cylindrical structure is embedded into the second cylindrical structure, and wherein the wavelength emitted from the plurality of plasmonic materials is commensurate with a bandgap of the plurality of photovoltaic cells;
• and
• producing electric charge from the plurality of photovoltaic cells.
