Abstract

The main purpose of the present paper is the study of the effect of different parameters of multi-layer anti-reflective coatings ARCs on the reflectivity of solar cells Silicon based. The distribution of the refractive index along different layers is performed following a linear gradient variation from the substrate to the ambient within predefined limits. Firstly the model of Oxynitride multi-layer anti-reflecting coatings was presented which is intended to be used in the evaluation of the performance and the process design of the ARCs in practical applications of solar cells. Secondly the presented model was tested under simulation face to different parameters constraints such as the thickness of the ARCs, the index gradient range variation, the gradient distribution and finally the incidence angle, where the main aim is to improve the quality of the solar cells based on the reflectivity evaluation. The obtained results were also compared to other previous works, whereas focusing on the advantages that have been brought by the proposed model. This paper is concluded by the representation of the main advantages that are needed to be validated by experimental measurements..
