all thin films grown via CVD or sulfidation to date have contained marcasite phase or other iron sulfide impurities. Here respectively with the ability to provide the material in a range of grind sizes suited to any operational need.Iron pyrite (FeS 2) is a naturally abundant and nontoxic photovoltaic material that can potentially make devices as efficient as silicon-based ones; however existing iron pyrite photovoltaic devices contain thermodynamically unstable FeS 2 film surfaces that lead to low open circuit voltages. We report the rational synthesis of phase pure
