The effect of a bilayer of different dimension silver nanoparticles (Ag NPs) on light trapping in silicon solar cells is investigated. Here, we report on the improved performance of silicon solar cells by integrating two layers of silver nanoparticles of different sizes. We experimentally examine the plasmonic near-field and far-field effects of bilayer Ag NPs embedded within an anti-reflective DLC layer on silicon solar cells' optical and electrical characteristics. Field-Emission Scanning Electron Microscopy drove the two-dimensional differences in the size of Ag NPs. The surface plasmon resonance of the two-dimensional nanoparticles was estimated from the absorption optical spectra. External quantum efficiency measurements showed that near-field or far-field plasmonic effects altered with the Ag NPs size. The development of far fields was confirmed by measuring the solar cell performance under AM 1.5 G illumination. The impact of the far-field in the cell containing two layers of Ag NPs, which outer layer is larger dimensions NPs, improves the current density up to 38.4 mA/cm2 (by 70% compared to the bare reference cell).

“…Many of the current researches attempt to gain a deeper and more insightful understanding of the physical properties of thin films. The two-dimensional (2D) nature of films leads to intriguing electrical, thermal and optical properties governed by the competition of surface and quantum confinement effects, which can be engineered with the controlled modification of film thickness, composition, and surface roughness [1][2][3][4]. Such materials and their controllable properties have attracted considerable attention due to their potential application in different segments such as solar cells [3,5,6], optoelectronic devices [7][8], recording media [9][10], electrodes for batteries [11], gas sensors [12], hydrogen production [13], and spintronics [14].…”

Nowadays, there is a great interest in designing and fabricating thin films with unique morphologies to improve the surface properties for various applications. In this regard, atomic force microscopy (AFM) is widely used to investigate the surface morphology of thin films. The high spatial and vertical resolution makes AFM capable of extracting surface micro-roughness information precisely. In this study, Ag-DLC films were deposited on different substrates using the RF-PECVD method. The morphological properties were studied by AFM analysis according to ISO 25178-2: 2012.The results of analyzing the AFM data demonstrate that a copper substrate is a good option for the fabricated silver film in this study, and it is a relatively ideal surface in terms of fractality.
