Abstract
AbstractThe hybrid solar cells (HSCs) are the most abundant solar cell structures with higher charge collection efficiency, newer power conversion mechanisms, coupled with low cost. Recent studies have shown that metallic nanoparticles (MNPs) embedded with nanopyramid (NP) structures help to improve the photo-absorption over a wide range of wavelengths. Nanopyramidal structures, which consist of the tapered sidewalls, ensure gradual increment in the refractive index as light travels from air to the optical nerve of NP. In our study, we have used gold (Au) MNPs, which absorb and scatter the incident light into the substrate with the help of plasmonic resonance effects. In the proposed ITO/PEDOT:PSS/c-Si HSC structure, Au MNPs are located in the gap between nanopyramid arrays and the bottom of silicon (Si) substrate with molybdenum trioxide (MoO3) coating. The optical simulation of HSCs is carried out using finite difference time domain (FDTD) module of Lumerical solutions software package.KeywordsHybrid solar cellsNanopyramidMetallic nanoparticlesPlasmonicsFDTD
