Abstract:
Energy conversion by means of thermophotovoltaics (TPV) technology becomes theinterest research field of scientists and emphasized have been made on opticalemissivity of the emitter properties and tailoring the emissivity spectrum with PV cellexternal quantum energy (EQE). Selective thermal emitters applied by researchers tonhanced the global efficiency of the system.Within the stage of design, simulationmethods such as finite difference-time domain (FDTD) used to determine optimumgeomtry and physical shape of emitters. In this paper, 1-D tungsten optimizedspectrally which correspond to GaInAsSb TPV cell. The emitter’s temprature is set to1000K and grooves engraved on the the surface of the emitter that illuminated byplanar light wave. This paper illustrate that monochromatic nano-structures surfacesexcite localized modes as regarded TM and TE. Also channel plasmon polariton(CPP) propagation by triangular groove investigated and efforts made to enhance thepropagation of these modes along the tip of the grooves.
