“…Various methods are used to calculate the reflectivity of ARCs, such as the Fresnel formula, Rouard's method, and the transfer matrix method (TMM) [9,14,15]. The TMM is most commonly used as it relates the tangential components of electric and magnetic fields across the boundary of layers [15]. Thus, the transfer matrix (2 × 2) for a single film with refractive index n 1 on substrate with refractive index n s is expressed as [17]:…”

“…ARCs containing a single layer can be nonreflective only at a single wavelength, generally at the middle of the visible spectrum, whereas ARCs containing a double layer are effective over the whole visible spectrum [10]. Many works have been reported on ARCs with different materials such as MgF 2 /SiNx by Dhungel et al [11], SiO 2 /TiO 2 by Lien et al [12], Al 2 O 3 /TiO 2 by Bahrami et al [13], MgF 2 /Ti 2 O 3 by Medhat et al [14], and SiNx/SiNx by Beye et al [15].…”

The aim of this work is to investigate the effect of single and double layer antireflection coating (ARC) on the performance of silicon solar cells. In this regard, various previous works on single and double layer ARCs have been consulted. Silicon nitride (Si 3 N 4) has been used as ARC material because of its varying refractive index (1.8-3.0). Numerical calculations have been performed to obtain the reflectance for single and double layer Si 3 N 4 using the transfer matrix method. Double layer antireflection coating (DLARC) of Si 3 N 4 is found to have significant advantages over single layer antireflection coating (SLARC). Calculated reflectances have been further used in the PC1D simulator as external reflectance files to study the performance of a silicon solar cell. As a result of the simulation, the reflectance is found to reduce from > 30% to < 2% with short circuit current of 3.86 mA/cm 2 and conversion efficiency of 20.22% for DLARC. Results obtained for DLARC were further compared with a reference cell (without ARC), a cell with SLARC, and a cell with zero reflectance on the front surface.

“…Buie et al [8] have studied thin films of silicon oxide and silicon nitride as antireflection coatings to minimize the reflection losses on silicon cells. Beye et al [9] have found that the antireflection effect of SiN x double-layer antireflective coating is better than that of single layer. Feng et al [10] have shown that the antireflective performance of multilayer coatings is enhanced when the number of coating layers is increased.…”

Metamaterial waveguide structures for silicon solar cells are a novel approach to antireflection coating structures that can be used for the achievement of high absorption in silicon solar cells. This paper investigates numerically the possibility of improving the performance of a planar waveguide silicon solar cell by incorporating a pair of silicon nitride/metamaterial layer between a semiinfinite glass cover layer and a semi-infinite silicon substrate layer. The optimized layer thicknesses of the pair are determined under the solar spectrum AM1.5 by the effective average reflectance method. The transmission and reflection coefficients are derived by the transfer matrix method for values of metamaterial's refractive index in visible and near-infrared radiation. In addition, the absorption coefficient is examined for several angles of incidence of the transverse electric polarized (TE), transverse magnetic polarized (TM) and the total (TE&TM) guided waves. Numerical results provide an extremely high absorption. The absorptivity of the structure achieves greater than 98 %.

The aim of this work is to investigate the effect of angle of incident light on the performance of silicon solar cell. In this regard, numerical calculations have been performed to obtain the reflectance for double layer antireflection coating (DLARC) of Si 3 N 4 at various angles of incidence (i.e. ) using transfer matrix method. Reflectances obtained, are found to increases with increase in angle of incidence. Calculated reflectances have been further used in the PC1D simulator as external reflectance files to study the performance of silicon solar cell. As a result of the simulation, the conversion efficiency (and short circuit current) of solar cell is found to decrease by 1.7% (0.062 mA/cm 2 ) with increase in angle of incidence from .
