A.Ennaoui proposed that FeS2 owns an appropriate band gap (0.95 eV) and large absorption coefficient, it can be used for solar materials.People had studied the light absorption characteristics of the FeS2 prepared by different methods, and believed that crystal grain size, defect density and crystalline quality are important factors that affect the light absorption properties.In order to take a depth study of the absorption properties, the research group has taken a study on light absorption characteristics of natural pyrite, the existence of Co, Ni impurities results in lower band gap and conversion efficiency.
