Fabrication and Characterization of 2-D Materials based Solar Cells

Abstract

A simple and cost effective technique is used to Fabricate 2-D Material based solar cells. In this work MoS2 and Graphene is fabricated by Exfoliation Method and by Chemical Vapour Deposition (CVD). By using CVD, growth of MoS2 Nano-wires form on Silicon substrates while by Exfoliation of graphite powder in DMF solvent is done to form Graphene and exfoliation of Bulk MoS2 powder is done in DMF to form mono or Bilayer MoS2. These Materials were characterized by Raman Spectroscopy , X-Ray Diffraction (XRD), UV visible spectroscopy, Atomic Force Microscopy (AFM) and Scanning electron Microscopy (SEM). Solar cell device is successfully fabricated on doped silicon substrate and tested by I-V curve of Solar Simulator. Silver back and front metal contacts were deposited by Sputtering method. 4.02% highest efficiency were obtained.
