| Abstract Scope |
2D materials have demonstrated significant potential as the next generation materials in applications in optoelectronic devices due to their anatomically thin bodies, high flexibility, and optical transparency. Graphene and the class of Transition Metal Dichalcogenides (TMDCs) have received particular attention as they may be used as absorber layer, electrode and window layer materials in photovoltaics. In this study, solar cells made of Copper Zinc Tin Sulfide (CZTS) are simulated utilizing the open-source software PC1D. The cell consists of a transparent top layer of graphene, with MoS2 as a buffer layer and CZTS as the absorber layer. The effect of graphene and buffer layer thickness, as a function of temperature, on the efficiencies of the cell have been simulated and results compared with literature. Results indicate an ideal graphene layer of 2nm and ideal buffer layer thickness dependent on doping concentration. |
