Iron Sulfide (FeS2) is a non-toxic material and is abundant on earth. Due both to its environmental compatibility and its optimal optical and electronic properties for efficient energy conversion, pyrite has the potential to underpin inexpensive and sustainable thin film PV technology. We synthesize and utilize FeS2 nanocrystals (NCs) for optical and electrical characterization, and for fabrication of thin films and PV devices. Synthesis of iron sulfide (FeS2) NCs has been performed using hot solution injection methods. Figure (a) on the right is a part of Schlenk line used for the synthesis of NCs, Raman spectra of FeS2 NCs is shown in figure (b). Figure (c) shows scanning electron micrograph (SEM) images of FeS2 NC films.
