Iron Pyrite Oxygen Alloy for Improved Photovoltaic Efficiencies and Increased Photovoltages
This alloy may be used in photovoltaic devices (solar panels).
Iron pyrite (FeS2) is a promising photovoltaic material because of its strong light absorption, sufficient minority carrier diffusion length, and relative abundance. However, the band gap of pyrite (Eg = 0.85-0.95 eV) is somewhat narrow for optimal photovoltaic applications and subsequently the open circuit voltage of pyrite based devices (Voc < 0.2 V) is too low. Researchers at the University of California, Irvine have developed a new iron pyrite oxygen alloy with a predicted band gap of 1.2-1.3 eV, compared to 0.85-0.95 eV for pure iron pyrite.
