Abstract

Thin-film photovoltaics offers the potential for a significant cost reduction compared
to traditional photovoltaics. However, the performance of thin-film solar cells is limited by poor
light absorption. We have devised an ultra-thin-film silicon solar cell configuration assisted by
plasmonic nanostructures. By placing a one-dimensional plasmonic nanograting on the bottom
of the solar cell, the generated photocurrent for a 200 nm-thickness crystalline silicon solar cell
can be enhanced by 90% in the considered wavelength range, while keeping insensitive to the
incident angle. These results are paving a promising way for the realization of high-efficiency
thin-film solar cells.
