Prospects of molybdenum disulfide (MoS₂) as an alternative absorber layer material in thin film solar cells from numerical modeling.

摘要

Molybdenum Disulfide (MoS 2 ) is a potential lo w cost, alternative sunlight harvester for a possible replacement of the conventional photovoltaic materials. It is a suitable photovoltaic absorber material mainly due to its optimum o ptical and electrical properties. In this work, we numerically analyze both hetero-junction and homo-junction device structures of MoS 2 by 1D-Solar Cell Capacitance Simulator (SCAPS). Both n-ZnO- CdS/p-MoS 2 and n-MoS 2 /p-MoS 2 show the conversion efficiencies above 19%. We also stud y various windo w layer materials to optimize the performance of the hetero-junction structure. The analysis includes the device stability as well operating temperature. The analyzed results indicate the feasible fabrication of high efficiency MoS 2 based solar cells
