title: Silicon nanowire radial p-n junction solar cells.
abstract: We have demonstrated a low-temperature wafer-scale etching and thin film deposition method for fabricating silicon n-p core-shell nanowire solar cells. Our devices showed efficiencies up to nearly 0.5%, limited primarily by interfacial recombination and high series resistance. Surface passivation and contact optimization will be critical to improve device performance in the future.
