Abstract
The present invention relates to coated binary and ternary chalcogenide nanoparticle compositions that can be used as copper zinc tin chalcogenide precursor inks. In addition, this invention relates to coated substrates comprising binary and ternary chalcogenide nanoparticle compositions and provides processes for manufacturing these coated substrates. This invention also relates to compositions of copper zinc tin chalcogenide thin films and photovoltaic cells comprising such films. In addition, this invention provides processes for manufacturing copper zinc tin chalcogenide thin films, as well as processes for manufacturing photovoltaic cells incorporating such films.
