“…Firstly, for the optical part, a self-program was designed by our team to calculate the thickness of each layer and the reflection at each wavelength of the ARC design for the cell surface, taking into account the dispersion relations of the materials used. A modified Lorentz-Lorenz relation for the material dispersion was used because its results represent truly the refractive index dispersion of the used materials [18]:…”

Antireflection coating on silicon, a high refractive index substrate, was theoretically investigated. The effects of antireflection coating on electrical parameters such as the short circuit current, open circuit voltage, maximum current density, maximum voltage, maximum power, power density, and conversion efficiency of the solar cell were simulated. Various previous works in which solar cell efficiencies were investigated after applying double layer antireflection coating (DLARC) were reviewed. Ti 2 O 3 and MgF 2 were then applied in a DLARC design, taking into consideration the refractive index dispersion of the two materials. The results were compared with other works in the solar spectral range (400-1200 nm). As a result of simulation, the reflectance on the surface was reduced from 30.2% to 2.37%. Moreover, about 22% conversion efficiency and 38.6 mA/ cm 2 short circuit current density were achieved for a silicon cell with DLARC. These results were compared with the parameters of a cell without coating, one with single layer coating, and one with zero reflectance on the front surface.

The approach utilized in the design of achromatic periods formed of two layers a high-index and a low-index is developed by combining the first two periods together. These two periods are therefore reduced to three layers a central one, an upper layer and a lower layer. Both the upper and lower layers are matched to the central at two different wavelengths. This forms the so called a combined achromatic period or the basic unit. Multilayers showing low transmittance bands are then synthesized of this basic unit. Parameters used in the synthesis of such multilayers are pointed out and their control role is investigated
