Abstract
In this paper, we have analyzed the role of single and dual nanostructures embedded in PEDOT:PSS (Poly (3,4-ethylenedioxythiophene):poly (styrenesulfonate))/c-Si Hybrid Solar Cells (HSCs) using Finite Difference Time Domain (FDTD) method. HSC structures with Nanopyramids (NPs) on top of the Si substrate exhibit optical J sc of 35.91 mA/cm 2 . We obtained significant improvement in J sc by 1.56% and 14% observed with the insertion of oxide coated Ag MNPs (Metal Nanoparticles) and Al MNPs in the rear and front end of the HSC, respectively. A comparative analysis of these three structures denoted as NP (for nanopyramids only), NP + Ag MNPs (nanopyramids with Ag MNPs embedded in the front end of the HSCs along with oxide coated MNPs in the rear end) and NP + Al MNPs (same as the second structure with Ag MNPs replaced with Al MNPs) shows that HSCs with NP + Ag MNPs and MoO 3 coating achieve the highest open circuit voltage (V oc ) of 0.7 V, electrical J sc of 22.19 mA/cm 2 , power conversion efficiency (PCE) of 12.56% and Fill Factor (FF) of 80.85%. • Role of nanostructures in PEDOT:PSS/c-Si solar cells studied using FDTD method. • Optimization of nanostructure done in terms of optical J sc . • J sc of 35.91 mA/cm 2 obtained with Nanopyramids (NPs) on top of the Si substrate. • NPs with metal nanoparticles at rear and back end of Si exhibits best PCE.
