Abstract

For a good understanding of electrical and optoelectronic parameters involved in the silicon photovoltaic cell, we study the solar cell that gives a general description of the different parts of the solar cell and some photovoltaic parameters in these parts of the external quantum efficiency, the refractive index on the deposits antireflective solar cells. The effect of a single anti-reflective coating (SiNx/Si) was studied. A clear improvement of the spectral response is observed in the area of wavelengths from 400 to 900 nm. An improved external quantum efficiency at long wavelengths is observed due to the low energy photons absorption, a remarkable increaseness in the specific wavelength, an area where the spectral response is dominated by the photogenerated carriers in the base.

Abstract

Solar cells thin layers are increasingly used in the last decades the performance of these cells were clearly improved. In the present work, we simulated a silicon solar cell to analyse certain parameters. Particularly the antireflective properties of the layer (thickness, refractive index) play a crucial role in the performance of the cell, and to optimize them, we studied their effect on the quantities of photovoltaic solar cell. In order to highlight the importance of the testimony of an antireflection coating (SARC) on silicon solar cells a comparison between two cells, one without anti-reflective layer (bare silicon), the other with a layer antireflection was made. The deposition of an antireflection coating shows a significant improvement is in addition to the benefits of the change or not the latter.

The reflection, transmission intensity and amplitude recorded by a simple matrix method are consistent with the literature.
