Spectral Response of a Monocrystalline Silicon Solar Cell: Under the Influence of the Variation of the Refractive Indices of the Antireflection Materials

Awa Dieye, Nacire Mbengue, Mayoro Dieye, Oumar A. Niasse & Bassioru Ba · Physical Science International Journal · 2022

Numerical simulations have shown that low reflectivity’s at the surface of the planar cell coated with a single layer can be obtained. For example, for single coatings of Si3N4 and HfO2 materials, reflectivity values of around 3% and 2% respectively are obtained. Structures with...

Three-dimensional Modeling Study of the Effect of Irradiation on a Single-face Polycrystalline Silicon Photocell under Multispectral Illumination

Mayoro Dieye, Nacire Mbengue & Awa Dieye · Physical Science International Journal · 2022

A three-dimensional modeling study of a polycrystalline silicon mono-facet photocell under multi-spectral illumination is presented highlighting the effect of irradiation energy (Φ) and damage coefficient (Kl) on the macroscopic parameters. Using the junction recombination rate S...

Theoretical Study and Modeling of a MgF₂/HfO₂ Double-layer Antireflection Coating for the Optical Detection of Nuclear Radiation

Alassane Diaw, Papa Touty Traore, Modou Pilor, Ismaila Badji, Moulaye Diagne, Nacire Mbengue & Oumar Absatou Niasse · Current Journal of Applied Science and Technology · 2026

Efficient photon transmission from scintillators to photodetectors is important for maximising the optical response of nuclear-radiation detection systems. This theoretical study evaluates a double-layer MgF₂/HfO₂ antireflection coating on a fused-silica optical window and compar...
