摘要: 利用脉冲激光沉积法(PLD)制备出高质量的Sb2S3薄膜.通过改变沉积时间来调节Sb2S3薄膜的厚度,进而研究不同Sb2S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2S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2S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.

Abstract: High quality Sb2S3 thin films were prepared by pulsed laser deposition (PLD) method. The thickness of the Sb2S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2S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2S3 layer and non-radiative recombination of photo generated carriers, thus affecting the efficiency of the solar cell.

Key words: Sb2S3, pulsed laser deposition, thin film, solar cells
