“…The maximum charge carrier generation rate for the optimized case V was evaluated to be 4.79 × 10 26 m −3 s −1 , which is ~ 2.4-fold higher than that of the reference. It is 10 26 orders of magnitude, which is similar to that previously reported for perovskite and/or Si solar cells 33 , 34 . Furthermore, the corresponding bandwidth of the carrier generation rate curve is substantially broader at 475 nm.…”

Embedded noble metal nanostructures and surface anti-reflection (AR) layers affect the optical properties of methylammonium lead iodide (CH3NH3PbI3) perovskite solar cells significantly. Herein, by employing a combined finite element method and genetic algorithm approach, we report five different types of CH3NH3PbI3 perovskite solar cells by introducing embedded Ag nanoparticles within the CH3NH3PbI3 layer and/or top ITO cylinder grating as an AR layer. The maximum photocurrent was optimized to reach 23.56 mA/cm2, which was 1.09/1.17 times higher than Tran’s report/ flat cases. It is also comparable with values (23.6 mA/cm2) reported in the literature. The calculations of the electric field and charge carrier generation rate of the optimized solar cell further confirms this improvement than flat cases. It attributes to the synergistic effect of the embedded Ag nanoparticles and ITO AR layer. The results obtained herein hold great promise for future boosting the optical efficiency of perovskite solar cells.

“…Thus, the amount of incident energy that reached the active area of the cell was decreased by increasing the thickness of the third layer of ARC. Accordingly, we fixed the thickness of the third layer at 8 nm to increase the transmission, and to reduce overall the reflection from the surface of the structure, especially in the visible spectrum [64,65]. Finally, we added Table 1 to compare our present work and the previous works in the literature survey to show the motivation and novelty of our work.…”

We have theoretically demonstrated an efficient way to improve the optical properties of an anti-reflection coating (ARC) and an intermediate reflective layer (IRL) to enhance tandem solar cell efficiency by localizing the incident photons’ energy on a suitable sub-cell. The optimum designed ARC from a one-dimensional ternary photonic crystal, consisting of a layer of silicon oxynitride (SiON), was immersed between two layers of (SiO2); thicknesses were chosen to be 98 nm, 48 nm, and 8 nm, respectively. The numerical results show the interesting transmission properties of the anti-reflection coating on the viable and near IR spectrum. The IRL was designed from one-dimensional binary photonic crystals and the constituent materials are Bi4Ge3O12 and μc-SiOx: H with refractive indexes was 2.05, and 2.8, respectively. The numbers of periods were set to 10. Thicknesses: d1 = 62 nm and d2 = 40 nm created a photonic bandgap (PBG) in the range of [420 nm: 540 nm]. By increasing the second material thickness to 55 nm, and 73 nm, the PBG shifted to longer wavelengths: [520 nm: 630 nm], and [620 nm: 730 nm], respectively. Thus, by stacking the three remaining structures, the PBG widened and extended from 400 nm to 730 nm. The current theoretical and simulation methods are based on the fundamentals of the transfer matrix method and finite difference time domain method.

“…In this section, the modelling and theoretical analysis of our proposed structure is study by COMSOL multiphysics based on the finite element method [FEM]. For more accurate results, the meshing size must be ten times smaller than the lowest incident wavelength [37,38]. Here, our design is one-dimensional photonic crystals with different surface shapes as in figure (1).…”

In this paper, we demonstrate a novel Salinity sensor based on Tamm-Plasmonpolariton (TPP), comprising of different shapes of Bragg reflector (ordinary, texturing, and Sawtooth) and metallic layer, is proposed. The finite element method is used to study the considered structure and sensing performance by using the COMSOL multiphysics simulation procedure. Here, we study the effect of surface morphology on the sensitivity; firstly, in the case of one-dimensional photonic crystals centered defect, it has a negative effect on the sensitivity, secondly, texturing and sawtooth in the case of Tamm resonance is increase the sensitivity as For texturing the surface, the sensitivity ( ) = 569 / , quality factor (Q)=236, and figure of merit (FOM) =170 −1 . While, for Sawtooth surfaces, = 612.29 / , Q =272.4, and FOM =199 −1 . The consequences of structural parameters on the efficiency of sensing are studied and new procedures are proposed to enhance TPP-based sensors. A simple and functional alternative to conventional salinity sensors may be the proposed solution.
