Patent No. 9,472,702

This patent implements a reaction to remove sulfur from gasoline at low temperature, at atmospheric pressure, and without the use of any oxidizing agents. These features allow for much cheaper removal of sulfur compounds from gasoline.

A photovoltaic solar cell comprises a nano-patterned substrate layer. A plurality of nano-windows are etched into an intermediate substrate layer to form the nano-patterned substrate layer. The nano-patterned substrate layer is positioned between n-type semiconductor layer composed of n-type semiconductor material and a p-type semiconductor layer composed of a p-type semiconductor material. Semiconductor material accumulates in the plurality of nano-windows, causing a plurality of heterojunctions to form between tn-type semiconductor layer and the p-type semiconductor layer.
