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.

Cdte Solar Cells

Thin film CdS/CdTe has long been regarded as one promising choice for the development of cost-effective and reliable solar cells. Efficiency as high as 16.5% has been achieved in CdS/CdTe heterojunction structure in laboratory in 2001, and current techniques for CdS/CdTe solar cells gradually step toward commercialization. This paper reviews some novel techniques mainly within two years to solve this problem from aspects of promotion of fabrication technology, structural modification, and choice of back contact materials.
