摘　　要：利用脉冲激光沉积法(PLD)制备出高质量的Sb_(2)S_(3)薄膜.通过改变沉积时间来调节Sb_(2)S_(3)薄膜的厚度,进而研究不同Sb_(2)S_(3)厚度对电池效率的影响.研究发现,当沉积时间为5 min时,Sb_(2)S_(3)太阳能电池效率达到最高,为3.98%.分析外量子效率和电化学阻抗谱发现,厚度的变化会影响Sb_(2)S_(3)层对光的吸收能力,同时也会增加光生载流子的非辐射复合,从而影响电池的效率.High quality Sb_(2)S_(3) thin films were prepared by pulsed laser deposition(PLD)method.The thickness of the Sb_(2)S_(3) thin film was adjusted by changing the deposition duration to investigate the thickness dependent power conversion efficiency in complete solar devices.It was found that the Sb_(2)S_(3) solar cell achieved power conversion efficiency of 3.98%when the deposition time was 5 min.Based on external quantum efficiency and electrochemical impedance spectroscopy analysis,it was observed that the change of thickness affects both the light harvesting capacity of the Sb_(2)S_(3) layer and non-radiative recombination of photo generated carriers,thus affecting the efficiency of the solar cell.
