Abstract
Abstract This paper addresses the possibilities of synthesizing copper indium gallium selenide nanoparticles with properties that are desired in photovoltaics. The use of oleylamine as solvent and capping agent improved the growth and dispersivity of stoichiometric CuIn0.75Ga0.25Se2 nanoparticles through conventional colloidal synthesis. Relatively small sized CuIn0.75Ga0.25Se2 nanocrystals were assembled in devices as quantum dot sensitized solar cells and exhibited electrical properties with a fill factor of 33% which may be improved for any photovoltaic application.
