摘要

Copper zinc tin sulfide (CZTS)-based solar power cells have gained the attention of researchers in the past few years due to their promising photovoltaic parameters. This paper presents a comparative performance analysis of two models of solar cells: FTO/TiO2/CZTS/Spiro-OMeTAD-based and FTO/TiO2/CZTS/CdTe/Spiro-OMeTAD-based. Heterostructured CZTS/CdTe-based solar cells provide high performance parameters compared with the performance of single-layered CZTS-based solar cells which have a more limited output for photovoltaic applications. The optoelectronic parameters of J–V and QE have been optimized to reach a high efficiency utilizing the 2D theoretical modeling tool, SCAPS 1-D. Moreover, the study has been extended by comparing the output parameters by considering the thickness, defect density, temperature, and back contact metal work function values for both models. The optimal output parameters obtained in this simulation are: JSC of 27.09 mA/cm3, VOC of 1.26 V, fill factor (FF) of about 89.34%, and a power conversion efficiency (PCE) of 30.58%, compared to a single active layer CZTS.
