Abstract

In this paper, we have studied the transparent oxide antireflective effects coatings on solar cell transmission at the n-CdS/p-CdTe heterojunction. We start from the results obtained on the determination of the optical constants by the dielectric function model which takes into account the contribution of the intermediate states. Thus, the transmission is studied to function to epitaxial layers thicknesses of cadmium sulphide CdS and transparent oxide ITO. Our results are compared with those of others authors for different calculation models. Thus, the study is extended to other transparent oxides such as Nb₂O₅ and Ta₂O₅ and to observe the effective influence on the quantum yield of the CdS/CdTe photocell. A table linking the transmission and the reflectivity of its various oxides as function to the thickness could thus be established.
