  • Conducting polymer and carbon nitride based nanocomposite photocatalyst for degradation of aqueous organic pollutants
    Patent number: 11819833
    Abstract: A nanocomposite photocatalyst is provided. The nanocomposite photocatalyst contains carbon nitride particles, a polymer composite comprising a conducting polymer and a carbon nanomaterial, the polymer composite being disposed on the carbon nitride particles, and noble metal nanoparticles disposed on both the polymer composite and the carbon nitride particles. Also provided is a method of forming the nanocomposite photocatalyst and a method of photodegrading an organic pollutant in water using the nanocomposite photocatalyst and visible light irradiation.

  • Eco-Friendly CuGaS2/ZnS Nanocrystals working as Efficient UV-Harvesting Down-Converter for Photovoltaics
    Publication number: 20200381570
    Abstract: Provided here nontoxic CuGaS2/ZnS core/shell nanocrystals with free-self-reabsorption losses and large Stokes shift synthesized on an industrially gram-scale. The nanocrystals exhibited a typical energy-down-shift that absorbs only ultraviolet light and emits the whole range of visible light with a high photoluminescence-quantum yield. The straightforward application of these energy-down-shift nanocrystals on the front surface of a monocrystalline p-type silicon solar cell significantly enhanced the short-circuit current density and power conversion efficiency. The significant improvement in the external quantum efficiency and that decreasing in the surface reflectance in the ultraviolet region clearly manifest the photovoltaic enhancement.
