Synthesis of single source molecular precursors for copper indium diselenide and copper indium disulfide production via confined plume chemical deposition

Jason D Jackson, Tennessee State University

Abstract

A one-step process for preparing coatings of known photovoltaic materials on either inorganic or organic substrates is reported. IR laser (2.94 µm wavelength) and femtosecond visible laser (800 nm wavelength) irradiation of single-source molecular precursors layered between transparent supports under temporal and spatial confinement at a laser wavelength (2.94 µm or 800 nm) resonant with a precursor vibrational band gives one-step deposition of copper indium diselenide (CISe) or copper indium disulfide (CIS) without incurring noticeable collateral thermal damage to the substrate material. Reaction plume formation at the precursor/laser beam interface initiates confined plume, chemical deposition (CPCD) of nano CIS product. Continuous coatings are produced by rastering the laser beam over a sample specimen. CPCD processing of precursors 1-6 on confined substrates, ultra high molecular weight polyethylene (UHMWPE)/glass, and glass/sapphire gives CISe, CIS respectively.^
