Abstract

Systems and methods are provided for the fabrication and manufacture of efficient, low-cost p-n heterojunction pyrite solar cells. The p-n heterojunction pyrite solar cells can include a pyrite thin cell component, a window layer component, and a top surface contact component. The pyrite thin cell component can be fabricated from nanocrystal paint deposited onto metal foils or microcrystalline pyrite deposited onto foil by chemical vapor deposition. A method of synthesizing colloidal pyrite nanocrystals is provided. Methods of manufacturing the efficient, low-cost p-n heterojunction pyrite solar cells are also provided.
