“…Furthermore, since the structure is completely symmetric, it provides exactly the same response for TE and TM polarisations of the incident light. The consistency of the absorption for TM and TE polarisations is one of the important advantages of the proposed solar cell when compared with previous works [12, 13, 20].…”

“…Metallic nano-particles [8,9], core-shell structures [10,11], grating structures [12,13], dielectric resonators [14,15], and optical metasurfaces [16][17][18][19][20][21] have been used in thin-film solar cells to enhance light absorption in these cells. In the grating structures, the light is coupled to the surface plasmon polaritons (SPPs) propagating along the metal-dielectric interface and then absorbed by the active layer [12,13]. When using nanoparticles, the light excites local surface plasmons (LSP) around nanoparticles leading to local field enhancement and absorption improvement [8][9][10][11].…”

In this article, a new structure for development of thin film solar cells is proposed in which elements with fractal shapes are integrated inside the cell to enhance its performance in a wide range of wavelengths. Two different structures are studied. In the first structure, a metallic fractal nano-carpet is integrated inside the silicon layer in order to trap and absorb sunlight by exciting surface plasmon polaritons and local surface plasmons at different wavelengths. Numerical analysis shows that this technique increases the short circuit current provided by the cell by a factor of 2.40 for both TM and TE polarisations of the incident light. The second structure has an active layer shaped as a fractal structure, and absorbs sunlight through Mie and Fabry-Perot resonances occurring at different wavelengths. The short circuit current enhancement for this structure is 2.97 for both TM and TE polarisations of the incident light, representing a significant improvement when compared with the previous works.

“…The energy trouble can be reduced through the conversion of sunlight into electricity [1]. Although the plasmonic solar cells low cost, it suffers from poor absorption of the infrared portion of the solar spectrum [2,3]. Recently light-trapping structures have been utilized in different ways to increase the absorption of plasmonic solar cells.…”

In this paper, a plasmonic solar cell using silver nanoparticles is presented. The unit cell structure composes of two layers, each containing a silver nanoparticle deposited on the absorber layer and covered with an indium tin oxide layer. Nanoparticle structure has been used for light-trapping to increase the absorption of plasmonic solar cells. By various light trapping techniques, light can be concentrated in a thin absorber layer. As it will be clarified, through varying the geometry of these nanoparticle structures, the absorption peaks can be directed. All simulation data are obtained using the finite element method. The proposed model achieves two absorption peaks existing at 1.07 μm and 1.17 μm, each with absorptions of around 50%. The parameters of optimized performance have been specified. The results indicate that this model shows an absorption full width at half maximum, reaching 122 nm. Moreover, it can be noticed that the absorption peak can be increased to reach 0.5. The proposed structure has potential applications in the absorption of the infra-red part of the solar spectrum.

“…SPPsbased devices, thanks to their unique features such as overcoming the diffraction limit, guiding and confining light at subwavelength scales, as well as the ability to carry and propagate both optical and electrical signals, provide a promising platform for development of next generation of photonic integrated circuits (PICs), which are ultra-compact and highly energy-efficient. As a result, a considerable number of research studies over the past decade has been devoted to investigate potential applications of plasmonic-based structures such as sensors and biosensors [4], [5], modulators [6], field-effect transistors (FETs) [7], splitters [8], light absorbers [9], [10] and so forth. In general, there are two distinct types of plasmonic waveguides, namely insulator-metal-insulator (IMI) and metal-insulator-metal (MIM).…”

A Multipurpose and Highly-Compact Plasmonic Filter Based on Metal-Insulator-Metal Waveguides

A multipurpose and ultra-compact nanoplasmonic wavelength filter based on stub structure in a metal-insulator-metal (MIM) waveguide is suggested and numerically investigated. A novel approach of connecting two stepped-like apertures to both input and output ports is applied to form Fabry-Perot (FP) cavities, which enabled the structure to act as a dual band-pass filter at wavelengths 1310 nm and 1550 nm. It is shown that the variation in cavities' length allows to realize a long-wavelength cutoff filter, and cutoff wavelength can be easily tuned by adjusting the length of the cavities. Furthermore, it is revealed that increasing the gap between the stepped-like apertures and the cavities provides a triple band-pass at telecom wavelengths, e.g., 1267.5 nm, 1414.19 nm, and 1644.7 nm. The tunable broadband high-pass wavelength filter is then achieved while the lengths of stepped-like apertures and stub resonators are set to be identical. Finally, a tunable nearly perfect absorber can be obtained by varying the width of stub resonators. Therefore, because of functionality, size, as well as efficiency the proposed plasmonic filter may greatly contribute to miniaturization of next generation of photonic integrated circuits (PICs), and find applications in on-chip integration and wavelength-division multiplexing (WDM) in optical communication systems.
