Performance analysis of near-field thermophotovoltaic devices considering absorption distribution

This paper elucidates the energy transfer and conversion processes in near-field thermophotovoltaic (TPV) systems, considering local radiation absorption and photocurrent generation in the TPV cell. Radiation heat transfer in a multilayered structure is modeled using the fluctuation–dissipation theorem, and the electric current generation is evaluated based on the photogeneration and recombinat...

Hot Carrier-Based Near-Field Thermophotovoltaic Energy Conversion.

Near-field thermophotovoltaics (NFTPV) is a promising approach for direct conversion of heat to electrical power. This technology relies on the drastic enhancement of radiative heat transfer (compared to conventional blackbody radiation) that occurs when objects at different temperatures are brought to deep subwavelength distances (typically <100 nm) from each other. Achieving such radiative he...

Mie-Metamaterials-Based Thermal Emitter for Near-Field Thermophotovoltaic Systems

In this work, we theoretically analyze the performance characteristics of a near-field thermophotovoltaic system consisting a Mie-metamaterial emitter and GaSb-based photovoltaic cell at separations less than the thermal wavelength. The emitter consists of a tungsten nanoparticle-embedded thin film of SiO 2 deposited on bulk tungsten. Numerical results presented here are obtained using formulae...

Sliver Cells in Thermophotovoltaic Systems

Thermophotovoltaic systems are direct conversion heat engines that use photovoltaic cells to convert radiant energy from a heated object to electrical energy. Sources of heat for thermophotovoltaic (TPV) systems include sunlight, the combustion of fossil fuels, radioactive decay and industrial waste heat. Previous modelling indicated that thin photovoltaic cells were optimal for use in TPV syst...

Overcoming the black body limit in plasmonic and graphene near-field thermophotovoltaic systems.

Near-field thermophotovoltaic (TPV) systems with carefully tailored emitter-PV properties show large promise for a new temperature range (600 – 1200K) solid state energy conversion, where conventional thermoelectric (TE) devices cannot operate due to high temperatures and far-field TPV schemes suffer from low efficiency and power density. We present a detailed theoretical study of several diffe...
