Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What we claim is: 1. A CZTS/Se precursor ink comprising: a) a fluid medium; b) coated binary or ternary copper-containing chalcogenide nanoparticles; c) coated binary or ternary tin-containing chalcogenide nanoparticles; and d) coated binary zinc-containing chalcogenide nanoparticles, wherein the molar ratio of Cu:Zn:Sn of the CZTS/Se precursor ink is about 2:1:1 and the ratio of total chalcogen to (Cu+Zn+Sn) of the CZTS/Se precursor ink is at least 1.…
