Graphene and MoS2 monolayers have little absorption due to their very low thickness. By introducing those materials in structure of a photonic crystal (PC), can increase the absorption. In this work, a PC structure with ternary periodicity in the form of (ABG)n CMoS2C (GBA)m is proposed, where A, B and C layers are the dielectric materials, G is denoting the Graphene and the segment CMoS2C is introduced as the defect layer. The absorption spectrum of the structure is investigated using the transfer matrix method. The results show that this structure has the one-way absorption in the visible spectral region. The effect of the defect layer location, the polarization and the direction of the incident field on one-way absorption behavior is studied and optimized. The location of the absorption mode is independent of the polarization type but its peak intensity and width in TE polarization dependent on incident direction varies by angle of incident. It should be mentioned that incorporating of graphene yield to enhancement of the absorption.
