Antimony sulfide, or stibnite (Sb2S3), has been investigated intensively in recent years as a promising material for nontoxic, environmentally friendly solar cells. It is now possible to fabricate thin photovoltaic films from an ink containing nanoparticles of stibnite, and to nanopattern those films for 2-D and 3-D structures of pretty much any shape. Such simple, cost-effective production methods fulfill prerequisites for reliable, widespread use.
