Paper Abstract

We have investigated simulation, fabrication, 2D tungsten PhC for selective emitters of TPV system. Using finite difference time domain simulations, we designed and fabricated a 2D W PhC with cylindrical cavities of diameter from 490 nm to 555 nm, depth 1.5 μm. This structure may have a cutoff near the wavelength of 2.0 μm. A marked enhancement is expected in the emissivity of the 2D W PhC at wavelengths below 2.0μm compared to flat W. By using standard silicon processing techniques that are simple, efficient and easily scalable, selective emitting structure can be fabricated at lower cost and reduced complexity of individual components.
