ABSTRACT
Vertically aligned CdTe nanorods were fabricated by electrodeposition and were applied for the active layer of solar cells after being combined with poly(3-octylthiophene) (P3OT), a conjugated polymer. The electrodeposited CdTe showed an n-type behavior with the electric resistivity and the electron density of 2×106 Ω cm, 1.3×1010 cm-3, respectively. Quantum efficiency curve of the hybrid solar cells exhibited a peak at the same wavelength as the optical absorption for CdTe nanorods. The hybrid solar cells demonstrated a power conversion efficiency of 1.06%, whereas the efficiency was only 0.0006% without the nanorods.
