英文摘要	Sb2Se3 holds a great potential for low-cost thin film photovoltaics because of its very attractive material and optoelectronic properties, and the demonstrated 5.6% certified efficiency and decent device stability. A full understanding of the influence of external impurities on the properties of Sb2Se3 films would help the further improvement of Sb2Se3 solar cells. In this work, we carefully characterized the Mg and Fe doping in Sb2Se3 films. Both Kelvin probe force microscope and Hall measurements revealed that Mg was largely inert while Fe introduced the n-type doping. Temperature-dependent conductivity and admittance further demonstrated that Fe doping introduced two defect levels within the bandgap with their positions similar to 0.3 eV and similar to 0.4 eV below the conduction band. We caution that iron contamination should be minimized for high efficiency Sb(2)Se3 solar cells. Published by AIP Publishing.
