In this manuscript, a thorough comparative analysis of six GaAs based different nanostructures (hollow and solid) is performed on the basis of their optical performance. These nanostructures are known to exhibit excellent anti-reflection properties, owing to their ability to generate a broadband absorption spectrum through efficient photon harvesting. Using the Finite Element Method (FEM) of the commercially available COMSOL Multiphysics package, the absorption characteristics, optical short circuit current density (JSC), electric field and photogeneration rates of six different nanostructures namely concentric nanocylinder (CNCy), hollow concentric nanocylinder (HCNCy), inverted nanopencil (INPe), hollow nanopencil (HNPe), nanorod + nanohemisphere (NR + NHe), and hollow nanorod + hollow nanohemisphere (HNR + HNHe) are computed. The optical performance of these nanostructures is largely dependent on their geometrical parameters such as filling ratio (FR=Diameter/Period), spacing and structural dimensions. The optimized values of these parameters can play a vital role in capturing the optical resonance modes by the nanostructures to produce absorption enhancement. It has been observed that the nanostructures with base diameter of 240 nm, period in the range of 300-350 nm and FR of 0.8 exhibit better optical characteristics. Optical JSC and optical efficiency of 29.45 mA/cm2 and 42.26%, respectively for CNCy nanostructure with FR of 0.8 and diameter of 240 nm is the highest among all the nanostructures. The effect of the angle of incidence of the photons striking the nanostructures on the average absorptance in both Transverse Electric (TE) and Transverse Magnetic (TM) modes are also investigated. In addition to this, we have also computed the effective refractive index for all the nanostructures using Maxwell Garnett formula in order to estimate the surface anti-reflection characteristics of these nanostructures.

“…In order to increase efficiency, light trapping techniques can be used for absorption enhancement [12]. Light trapping can be done using nanostructures [13,14], metal nanoparticles [15], and also grating structures [16][17][18]. Intermediate band [19], and hot carrier extraction [20] are other quantum mechanics phenomena to promote the efficiency of SCs.…”

Absorption enhancement of Perovskite solar cells using multiple gratings

Perovskite Solar Cells have very low absorption in the near-infrared region. In this paper, in order to enhance the absorption in this region, a new technique has been presented based on multiple excitations of plasmonic modes through the gratings on the backside of the cell. Gratings on the backside of the active layer lead to absorption enhancement by exciting localized surface plasmons and light scattering, and since the resonance of surface plasmons is highly dependent on the dimensions of the gratings, the resonance wavelength can be adjusted by accurately determining the dimensions of the gratings. In order to simultaneously increase in several wavelengths, multiple gratings have been used on the backside of the cell. In using multiple gratings, the absorption in the near-infrared region has been increased many times by choosing the appropriate dimension of gratings. The highest average absorption of 68.46% has been achieved using five gratings which is a 50% increase compared to the structure without gratings. The simulation results under incident angles from 0 to 85 degrees indicate that gratings enhance light absorption up to an angle of 45 degrees. Meanwhile, the structure with five gratings degrees has an average absorption close to 70% up to an angle of ±45 degrees and is not sensitive to the incident angle. These multiple nanostructures have the ability to trap more light inside the active layer and thus promise a high-efficiency solar cell.
