AbstractThin-film CdTe solar cells are very promising for future cost-effective photovoltaics. The photovoltaic effect in these cells is based on the extraction of photoexcited carriers by the field provided by the CdTe/CdS heterojunction. An additional interface with non-rectifying characteristics is needed to close the external circuit on the other side of the CdTe thin film. Finally, the transport of photoexcited carriers is influenced by the presence of grain boundaries (GBs). In this contribution, we investigate several aspects of these interfaces and their effects on the operation of CdTe solar cells by electron-beam-induced current (EBIC) and cathodoluminescence (CL) measurements.

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/SnO2/CdS structure through the deposition of the intermediate SnO2 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 Sb2Se3, where the use of this type of HRT has not been studied.
