  • Patent number: 10622497
    Abstract: An inorganic nanocrystal solar cell comprising a substrate, a layer of metal, a layer of CdTe, a layer of CdSe, and a layer of transparent conductor. An inorganic nanocrystal solar cell comprising a transparent conductive substrate, a layer of CdSe, a layer of CdTe, and a Au contact. A method of spray deposition for inorganic nanocrystal solar cells comprising subjecting a first solution of CdTe or CdSe nanocrystals to ligand exchange with a small coordinating molecule, diluting the first solution in solvent to form a second solution, applying the second solution to a substrate, drying the substrate, dipping the substrate in a solution in MeOH of a compound that promotes sintering, washing the substrate with iPrOH, drying the substrate with N2, and heating and forming a film on the substrate.

  • Patent number: 10043939
    Abstract: A technique is described depositing a new formula of indium and tin salt solutions as a precursor to form a solid transparent indium tin oxide (ITO) film on non-conductive solid substrates. The utilization of this new composition of matter prompted the discovery of a method for preparing the first top-to-bottom completely solution processed solar cell. The specific patterning of the liquid-processed ITO precursor solution and the subsequent layers of a solar cell outlined here also demonstrate a unique way to connect solution processed (as opposed to deposited using vacuum techniques) solar cells in series and in parallel. Also disclosed are related methods for zinc tin oxide (ZTO), indium oxide (IO), indium zinc oxide (IZO), cadmium tin oxide (CTO), aluminum zinc oxide (AZO), and zinc oxide (ZO).
