Abstract
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 N, and heating and forming a film on the substrate. 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.
