Using electron tubes to generate solar power

Rolling an atom-thick semiconductor layer into a nanoscale tube allows it to convert solar energy into electricity without the need for semiconductor junctions — prerequisite features of conventional solar cells. . light energy) into an electric current. Strano's nanotube antenna boosts the number of photons that can be captured and transforms the light into energy e unabsorbed photons to thermal energy. Implement conversion efficiencies. The foundational. . The discussion explores the feasibility of using focused sunlight to heat a tungsten cathode for thermionic emission instead of traditional electric resistance heating.
