Two approaches for using nanowires, including core–shell structures, to improve photovoltaics

By / September 2, 2011

Schematic shows how to make core/shell nanowire solar cell starting from left with a CdS nanowire (green) that is dipped in CuCl where cation exchange reaction creates a Cu2S shell coating (brown). Metal contacts are then deposited on the CdS core and Cu2S shell. Credit: Yang et. al. By sheer coincidence, I received information about…
