To increase the density of electric power generation in thermophotovoltaic(TPV) system, an electricity generation experiment was conducted with InGaAs TPV cell and thermal radiation emitter made of tungsten with the cyclic pillar-array structured surface, facing each other in 100 nm. The nano-scaled gap is created by inserting SiO2 spacers. The experimental results did not show the density of electric power generation is getting to increase in near-field but showed the increment of electric power generation due to the pillar-array structure. Furthermore, the heat transport quantity by near-field radiation and electric power generation were simulated numerically and compared with experimental results.
