Surface thermal stability of iron pyrite nanocrystals: Role of capping ligands

Abstract

a r t i c l e i n f o Keywords: Iron pyrite FeS 2 nanocrystals Thin films Ligand exchange Surface stability Photovoltaic Iron pyrite (FeS 2) is a promising photovoltaic absorber material with a high natural abundance and low cost, but surface defects and low photoresponse inhibit sunlight energy conversion. The surface stability of pyrite FeS 2 nanocrystals… (More)
