Olivia Lenz: Iron Pyrite for Photovoltaics
Abstract:
Iron pyrite (FeS2) has the potential to be a low-cost, non-toxic, light weight, highly absorbing material for use in photovoltaics (PV). Current PV technologies rely on toxic materials (Cd, Te), non-earth abundant materials (Indium) and/or energy-intensive manufacturing techniques (Si). This talk will introduce and briefly discuss the motivation and progress in developing pyrite for PV, as well as some of the material and manufacturing challenges currently under investigation. Solar energy conversion is an area of work that is vital to NASA space missions and beyond. Lower-cost, lighter weight and durable photovoltaics are necessary to decrease spacecraft weight, allowing for increased exploration of the surrounding universe, making space for cutting-edge science instruments. Investing in solar energy technology for space applications can easily transfer to improved materials and device fabrication for earth-based solar cells, aligning with NASAs mission to benefit all mankind through scientific discovery.
