  • Light harvesting supercapacitor and method of preparation thereof
    Patent number: 11749466
    Abstract: A light harvesting supercapacitor and a method of preparing the light harvesting supercapacitor are disclosed. The light harvesting supercapacitor includes a transparent substrate, an active layer including TiO2 nanoparticles and polyaniline (PANI) nanoparticles disposed on the transparent substrate, an electrolyte layer including a solid separator and poly(2-acrylamido-2-methyl-1-propanesulfonic acid) disposed on the active layer, a carbon electrode disposed on the electrolyte layer; and a metal layer disposed on the activated carbon electrode. The method of preparing the light harvesting supercapacitor involves pulsed laser ablation in a liquid of bulk PANI to form the PANI nanoparticles. The light harvesting supercapacitor can be used in a photovoltaic device.

  • Fabrication of platinum counter electrodes for bifacial dye-sensitized solar cells
    Patent number: 11049666
    Abstract: A fabrication method for a flexible bifacial dye-sensitized solar cell is described. The method involves forming a flexible counter electrode of crystalline Pt nanoparticles on a first conductive layer by irradiating a precursor solution with a UV lamp. A flexible photoanode is formed by applying metal oxide particles to a second conductive layer, and then the solar cell is constructed by sandwiching an electrolyte between the counter electrode and photoanode.

  • Membrane for oil-water separation and simultaneous removal of organic pollutants
    Patent number: 10525419
    Abstract: An oil-water separation membrane is described. The oil-water separation membrane comprises a porous metal sheet with a photocatalyst layer on one side and a layer of nanoparticles and a surfactant on the other side. The layer of nanoparticles and surfactant create a superoleophobic and superhydrophilic coating that allows passage of an aqueous phase and rejection of an oil phase. The photocatalyst layer, combined with UV irradiation, enables degradation of organic contaminants in the aqueous phase. The oil-water separation membrane may be used as part of an oil-water separation system, and a filtered water product may be recycled through the membrane to increase the removal of organic contaminants.
