“…) is another important quantity used to evaluate solar cells and is obtained as follows: 7 When L(λ) is the absorption power normalized, I(λ) is the radiant heat ux of the sun at AM1.5 and q is the initial charge. This equation shows us how nanoparticles stimulate the electrons around them [42].…”

The present study deals with the effect of the presence of cylindrical aluminum nanoparticles on the parameters of short circuit current density and absorption in the active layer of ITO/PEDOT:PSS/P3HT:PCBM/ZnO/Al organic solar cell by means of the Finite-Difference Time-Domain (FDTD) method. The nanoparticles are located in a hexagonal pattern inside the P3HT:PCBM layer and on its border with ZnO. During the simulation, the AM1.5 standard sun spectral pattern has been used in the spectral range of 300-1200 nm. Calculations have shown that the presence of nanoparticles causes a considerable improvement in the values of the parameters. This increase is especially noticeable in the range of high wavelengths. Given the results, when the nanoparticle height is changed, the optimal thickness is also changed, where the short circuit current density and the absorption have the highest values, in a way that at the heights of 50, 100 and 150 nm for nanoparticles, the P3HT:PCBM layer is optimal in the thicknesses of 150, 200 and 250 nm. These results are independent of the radius of nanoparticles. Comparison of calculation results in different conditions shows that both the short circuit current density and the absorption will have the highest values for 150 nm thickness of P3HT:PCBM layer and for nanoparticles with 50 nm height.

“…Photovoltaics costs need to be reduced to increase their role in supplying energy [6]. Thin-film cells are an interesting alternative [7][8][9][10][11][12]. Thin film silicon solar cells can be considered as a good choice for cost reduction since they decrease the material required for production.…”

The main aim of this research work is to significantly improve the photocurrent of an ultra-thin silicon solar cell. Here, cylindrical shape cascaded plasmonic nanoparticles are used to design an ultra-thin silicon solar cell. The main idea is to manipulate the absorption spectra of a thin absorber by applying four cascaded cylindrical shape nanoparticles from different materials with different radii and heights. At first, a cell with one nanoparticle at the surface and another one with a nanoparticle at the bottom side are simulated, and their photocurrents are determined. Then, a cell with four cascaded Ag, Al, Ag-Al, and Al-Ag nanoparticles is simulated. The maximum photocurrent density and efficiency of 23.46 mA cm−2 and 13.95%, respectively, are obtained for a cell in which Ag and Al’s nanoparticles are used alternatively from top to bottom. The photocurrent density is 8.2 mA cm−2 for a cell without any nanoparticles. The simulated results show that cascaded nanoparticles significantly enhance the photocurrent. Finally, the generation rate is presented at different wavelengths.

“…Plasmonic nanostructures able to control light in space smaller than the diffraction limit, have a widespread application in waveguides, detectors [1][2][3], solar cells [4][5][6][7][8], and lasers [9]. Based on the precise permeability function of metals, their optical properties are inherently dependent on the fluctuating behavior of electrons in the metal.…”

In this research, an optimum design for better usage of field resonance was proposed. More interaction of the field that formed around nano-particles with a solution which has refractive index variations substantially can increase the sensitivity of the plasmonic biosensors. More interaction could be provided by floating nano-particles in the solution. The proposed structure, which has peak plasmonic resonance, has better light sensing features in comparison to similar non-floating structures. While without floating nano-particle, sensitivity is 265.8 nm/RIU with the realization of the full floating nano-particles, the sensitivity of the structure with elliptic disc and circular disc nano-particles are 574.2 nm/RIU and 425 nm/RIU, respectively. FWHM (Full width at half maximum) of the structure with elliptic disc and circular disc nano-particles are 57.4 nm and 49.4 nm, respectively. In presence of meshed SiO2 network and pseudo-floating form, sensitivity and FWHM of the structure are 504 nm/RIU and 58.4 nm for elliptic discs and 372 nm/RIU and 49.9 nm for circular discs, respectively.
