Electromagnetic Modelling of Solar Light Harvesting

Prof. Davide Mencarelli
Università Politecnica delle Marche, Italy

Abstract: Research on energy harvesting device points to the integration the energy-harvesting component in self-powering nano-systems. Prototypes of the integrated components will be developed incorporating nano-optical antennas with nano-rectifiers, namely rectennas, and micro-energy storage components. Here it is shown, through numerical simulations, that nanoarray antennas with small lattice pitch provides frequency flattening of the lattice impedance over the whole solar spectrum, eventually allowing for excellent matching with the antennas’ loads. Also, the small pitch allows for a smooth dependence of the receiving efficiency on the angle of incidence of sunlight. It is also shown numerically that the reflecting mirror also allows for an almost complete cancellation of light scattered by the receiving antennas. The final result is a polarization insensitive receiving theoretical efficiency over the whole solar spectral range.
