摘　　要：将 Cd S纳米粒子复合在 Ti O2 纳米多孔膜上 ,用染料 Ru( bpy) 2 ( NCS) 2 对此复合半导体纳米膜电极进行敏化 ,测量了不同 Cd S复合量的 ITO/Ti O2 /Cd S/Ru( bpy) 2 ( NCS) 2 光阳极组成光电池的能量转换效率 .实验证明 ,ITO/Ti O2 /Cd S/Ru( bpy) 2 ( NCS) 2 作为太阳电池光阳极的能量转换效率与 Ti O2 /Cd S复合半导体中 Cd S的含量有关 .当 Cd S复合时间为 5 min的电池的短路电流为 5 .2 3A/m2 ,开路电压为 0 .71 6 V,能量转换效率为 0 .77% .The CdS nanoparticles were formed in the holes of a TiO 2 nanoporous film, named as TiO 2/CdS composite semiconductor nanoporous film. The films were then sensitized by Ru(bpy) 2(NCS) 2. The conversion efficiency of light to electricity for the TiO 2/CdS/Ru(bpy) 2(NCS) 2 composite semiconductor nanoporous films was investigated as function of the deposition time of CdS on TiO 2 and it was proved that the efficiency was dependent on the depositing time. When CdS was deposited on TiO 2 for five minutes. The resulting cell had an energy conversion efficiency of 0 77%, with open circuit voltage of 0 716 V and short circuit current density of 5 23 A/m 2.
