This project is pursuing development of pyrite iron disulfide (FeS2), an Earth-abundant chemical, as a sustainable light-absorbing material for low-cost solar cells. Capitalizing on their recent discoveries, the researchers are investigating two related approaches to making pyrite-based solar cells that have never previously been possible: 1) making solar cells only from FeS2 and 2) combining FeS2 with silicon to reduce the cost of commercial silicon solar cells.This project is supported by IonE’s Renewable Electricity for Minnesota’s Future grant program.
