纳米级PbS，特别是量子点（QD），由于其带隙可从0.5至3eV调节，在诸如太阳能电池和光电探测器的应用中是令人感兴趣的。最近，已经报道了具有8.55%转换效率的ZnO/PbS太阳能电池，其具有由配体交换的PbS QD沉积的膜。然而，纳米晶PbS比量子点更容易制备。本文报道了理论研究使用纳米PbS代替量子点作为太阳能电池吸收剂。利用SCAPS软件模拟了SLG/ITO/ZnO和CdS/PbS/Al结构的太阳电池。我们使用了两种n型材料，一种是ZnO，另一种是CdS。通过电流-电压（I-V）特性和量子效率（QE）研究了模拟器件的性能。最后的结果表明，功率转换效率，
Nanoscale PbS, especially quantum dots (QDs) are of interest in applications, such as, solar cells and photodetectors because of tunability of band gap from 0.5 to 3 eV. Recently, ZnO/PbS solar cells with 8.55 % conversion efficiency have been reported with films made deposited from ligand exchanged PbS QDs. However, nanocrystalline PbS is easier to fabricate than QDs. This paper reports theoretical investigation into the use of nanocrystalline PbS in place of QDs as solar cell absorber. Solar cells with a structure of SLG/ITO/ZnO or CdS/PbS/Al was simulated using SCAPS software. We have used two n-type materials one is ZnO and second is CdS. The comparative simulated device performance was studied by currentvoltage (I-V) characteristics and quantum efficiency (QE). The final results reveal a power conversion effi-
