Pyrite thin films were deposited on glass substrates by a new and simple spray method using polyvinylidene fluoride as polymeric binder. Prepared pyrite films were characterized by field emission scanning electron microscopy, ultraviolet-visible spectroscopy and Hall auto-measuring instrument. Hall measurements showed p-type conduction of all the prepared thin films. The film prepared by using binder concentration of 2 wt.% showed the best results. Its band gap was estimated 1.55 eV. Also, electrical characteristics of the deposited film were obtained by I-V characteristic curve.
