(Color online) (a) Current density-voltage characteristics of the hybrid axial junction cell (red circles) and the hybrid radial junction cell (black squares) under 100 mW/cm2 AM 1.5G simulated solar illumination. (b) Spectral responses of the hybrid axial junction cell (red circles) and the hybrid radial junction cell (black squares).

FIG. 4.

(Color online) (a) The open circuit voltage (Voc ) decay of hybrid radial junction cells with different nanowire lengths. The inset shows the schematic energy band diagram and Voc for the hybrid Si/PEDOT:PSS Schottky junction in quasi-equilibrium states. (b) Spectral responses of hybrid radial junction cells with different nanowire lengths. The inset shows the enhancement of external quantum efficiency for the solar cells with 3.1 and 1.8 μm long Si nanowires with respect to the cell with 6.6 μm long Si nanowires.
