采用电沉积法制备了垂直取向的CdTe纳米棒，并将其与共轭聚合物聚3-辛基噻吩（P3 OT）复合后应用于太阳能电池的有源层。电沉积的CdTe呈n型结构，电阻率为2×106Ωcm，电子密度为1.3× 1010 cm −3。量子效率曲线在与CdTe纳米棒光吸收波长相同的波长处出现峰值。混合太阳能电池的功率转换效率为1.06%，而没有纳米棒的效率仅为0.0006%。
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 2×106Ωcm, 1.3×1010cm−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.
