Porous silicon (PSi) improves the performance of commonly used silicon solar cells due to its large surface-to-volume ratio and high light absorption capability. PSi increases light absorption and power conversion efficiency (PCE) compared to traditional silicon solar cells. Due to the unique optical properties of transition metal dichalcogenides (TMDCs), device performance improves when a TMDC layer is added to PSi-based photonic devices. However, only three studies in the literature have investigated TMDC/PSi structures so far. In this study, a Gr/ReS₂/PSi/p-cSi solar cell structure is discussed. In the proposed structure, Gr, ReS₂ and PSi are used as transparent conductive electrode, interlayer and absorber, respectively. The effects of thicknesses, N_C and N_V, and doping concentrations of the graphene, ReS₂ and PSi layers are examined and the layers are optimized. J_SC, V_OC, FF and PCE values of the …
