Nanostructured chalcogenides with adequate functionality are readily dispersible in various solvents to create colloidal solutions. Such dispersions, often called inks, could be easily coated in large areas on conducting substrates, conferring an inexpensive and robust method to construct thin films for photovoltaic applications. The processing required for obtaining uniform and dense nanostructured coatings is governed by the ability to tailor particle size, particle size distribution, nanoprecursors' surface and select appropriate dispersion reagents. Each type of nanostructure is unique and finding a specific set of conditions require in-depth analysis of properties such as purity, surface properties, and morphology of nanostructures.<br/>The presentation will comprise our discoveries in thin-film chalcogenide photovoltaics (PV) when utilizing colloidal dispersions of nanostructured materials, including Cu2ZnSnS4, Cu2SnS3, Fe2GeS4, and more.
