I-Vand external quantum efficiency characteristics of the cells. (a) Measured I-V characteristics of the SiNW-based solar cells (red dot line for cell with acid treatment and green triangle line for cell without acid treatment) and a corresponding planar silicon thin-film cell (black square line). (b) The external quantum efficiency of the SiNW-based solar cells and planar thin-film solar cell.
