In this work we describe how to model the efficiency of solar cells with novel metamaterial coatings optimized
for light harvesting. Full device modeling is implemented using optical and electrical simulations. As a proof
of concept, we simulate the operation of a metamaterial contact on a first generation monocrystalline silicon
solar cell. We compare device characteristics and efficiencies to standard antireflective coatings applied to a grid
contact cell. The effects of the metamaterial contact on silicon solar cell efficiencies is discussed for PN junction
and metal-insulator-semiconductor cell structures. It is found that the metal-insulator-semiconductor solar cell
designed performs better than the PN junction cell.
