The deposition of a high resistivity transparent (HRT) oxide between a transparent conductive oxide (TCO) and the window CdS has demonstrated the improvement of performance of CdS/CdTe solar cells, fabricated in the superstrate-configuration. In this work the influence of the pneumatic spray pyrolysis (PSP) and magnetron sputtering techniques on the properties TCO/SnO 2 /CdS structure through the deposition of the intermediate SnO 2 between the commercial conducting glass and CdS window is presented by means of X-ray photoelectron spectroscopy (XPS), secondary ion mass spectroscopy (SIMS), and contact resistance, calculated using transmission line method (TLM), in order to reduce the front contact resistance in devices with superstrate-configuration. The results of this work are applicable to other solar cells in the same configuration as the recent solar cells based on the compound Sb 2 Se 3 , where the use of this type of HRT has not been studied.
