20 September 2011Optical simulations and prototyping of microcrystalline silicon solar cells with integrated plasmonic reflection grating back contacts
Light-trapping is a key issue for high efficiency thin-film silicon solar cells. In this work, the interaction of incident light
with microcrystalline silicon solar cells applying a plasmonic reflection grating back contact is studied with threedimensional
electromagnetic simulations and via the measured spectral response of prototypes. The investigated
plasmonic reflection grating back contact consists of half-ellipsoidal silver nanostructures arranged in square lattice at
the back contact of a n-i-p substrate type microcrystalline silicon solar cell. Experimental results of prototypes of these
solar cells show significantly enhanced short circuit current densities in comparison to flat cells and even a small
enhancement of the short circuit current density in comparison to the conventional random texture light-trapping concept
of thin-film silicon solar cell. A very good agreement was found for the simulated and measured spectral response of the
solar cell. From the simulated three-dimensional electromagnetic field distributions detailed absorption profiles were
calculated allowing a spatially resolved evaluation of parasitic losses inside the n-i-p type microcrystalline silicon solar
cell.
