Abstract	Iron pyrite, $FeS_{2}$ is a semiconductor that has attention as next generation material for solar cells. We reported the evaluation of band structure and the conductivity of $FeS_{2}$ thin film toward a realization of $FeS_{2}$ heterojunction solar cells. $FeS_{2}$ thin film was prepared by spin-coating. The pyridine solution which included Iron(III) acetylacetonate was utilized as a precursor ink and the precursor film was deposited on non-alkali glass by spin-coating. The deposited film were prebaked in air at 320°C for 15 min and annealed in sulfur gas for 60 min. The ionization potential, the Fermi level, and the bandgap were measured by PYS, valence band spectrum using XPS, and UV-Visible light transmission, respectively. In addition, the resistivity of the prepared thin film was also evaluated.
