In recent years, plasmonics has been widely employed to improve light trapping in solar cells.Silver nanospheres have been used in several research works to improve the Fan Shop - NHL - Jerseys capability of solar absorption.In this paper, we use silver pyramid-shaped nanoparticles, a noble plasmonic nanoparticle, inside thin-film silicon and InP solar cells to increase light absorption compared to previously published topologies.The proposed structure consists of a TiO2 pyramid structure placed at the top of the surface working as an anti-reflective layer, silicon/indium phosphate as an absorption layer, silver pyramid-shaped nanoparticles incorporated inside the absorption layer, and an aluminum reflecting layer at the bottom.
In this research, we used finite difference time domain (FDTD) simulation to model the thin-film solar cell (TFSC).Optimizing the shape and placement of the silver pyramids, we have achieved an efficiency of 17.08% and 18.58% using silicon and InP as the absorbing layers respectively, which is significantly better than previously reported studies.
The open-circuit voltages are 0.58 V and 0.92 V respectively, which is the highest among other configurations.To conclude, the findings of this study laid the foundation to create an efficient thin-film solar cell utilizing the light-trapping mechanism of Wraps noble plasmonic nanoparticles.
