Abstract :
Excitation of surface plasmon polariton (SPP) in Sub-wavelength dielectric/metal structures is a key to enhance the light absorption of thin film solar cells (TFSCs). We design a SiO2/Ag nanostructured grooves geometry at the rear-side of a Si-based TFSC to excite SPPs. This geometry scatters light inside absorber layer in many directions resulting in absorption enhancement. In addition, we consider SiO2 corrugated strip geometry at the top of the absorber layer as light trapping technique. The height and width of the SiO2 strips are 60 nm and the height and width of the grooves are 30 nm. We apply this technique in the Si-based TFSC that contains Ag/graphene nanoparticles (NP-TFSC) in absorber layer as localized plasmon resonance elements. The thickness of absorber layer is 800 nm. We simulate this TFSC utilizing FDTD method. Results of simulations reveal a 21.36% absorption enhancement, a 16.39% Jsc increment and a 3.9% in conversion efficiency improvement.
