Thermal energy storage (TES) supported concentrating solar power (CSP) systems with 3Dprinted photon-enhanced thermal field emission (PETFE) converters and plastic reflectors could
dramatically lower the cost and energy payback time of the CSP technologies. The PETFE panels
with a transparent anode, carbon nano-tube (CNT) ink printed on a dielectric substrate as a
cathode surrounded on both sides by a gate can be used for direct on-sun heating and thermal
insulation of the TES during off-sun hours. An additional PETFE converter design could have a
thin anode containing a large number of cooling micro-channels to serve as the CSP receiver. CO2
gas from the PETFE anode at the temperatures of about 650°C heats sCO2 Brayton and/or steam
Rankine cycles.
