Thermal energy conversion using near-field thermophotovoltaic device composed of a thin-film tungsten radiator and a thin-film silicon cell

摘要: In this paper, we proposed a novel nano-gap thermophotovoltaic (TPV) device made up of thin-films including the radiator. The optical, electrical, and thermal responses performance were assessed using coupled opto-electro-thermal numerical simulation. design consists thin-film tungsten radiator which is paired with silicon TPV cell across nanometric vacuum gap. Results simulated based on experimental properties available in current literature database. It discovered that maximum electrical power output increases temperature to certain threshold value due improvements generated photocurrent. Thin-film as shown improve radiative heat transfer above bandgap compared conventional bulk tungsten. effect thickness was also analysed. A 1-μm produces better over thinner thicknesses at cost greater cooling requirements. However, offset costs, allowing for consistently favourable efficiencies. Finally, it profile under convective can be approximated uniform, simplifying transport modelling process.In ...
