This paper describes an electrodeposition technique facilitating in situ doping of CdTe with Sb in an electrodeposition bath containing CdCl2, TeCl4, KI and SbCl3 in ethylene glycol at 160°C. The composition and structure of the undoped and doped films have been analysed using XPS, PIXE and XRD. It is shown that the Sb doped films contained relatively low percentage of oxygen. Moreover, Sb doping promotes preferential orientation of low index (111) plane of CdTe films. The direction of thermo-emf developed in p-type Sb-doped CdTe has also been shown to be opposite to the thermo-emf measured for undoped CdTe films.
