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. http://pubs.sciepub.com/ajmse/6/2/4/ajmse-6-2-4.pdf transmission reflection quantum efficient solar cells heterojunction cadmium telluride cadmium sulfide
