METHOD TO SYNTHESIZE COLLOIDAL IRON PYRITE (FeS2) NANOCRYSTALS AND FABRICATE IRON PYRITE THIN FILM SOLAR CELLS

摘要

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.

1. A method for producing pyrite thin films, comprising the steps of
depositing a p-type pyrite thin film comprising colloidal iron pyrite nanocrystals onto a conductive bottom substrate, the conductive bottom substrate acting as an electrical contact; and sintering the p-type pyrite thin film in sulfur-containing atmospheres.
