摘要：

We investigate the distribution of Cu acceptor states in CdTe thin films used in high-efficiency solar cells. These states are Cu-Cd and Cu-i(+)-V-Cd(-) complexes, which are relatively deep and shallow acceptors, respectively. Cathodoluminescence spectroscopy and imaging show that, first, Cu-Cd and Cu-i(+)-V-Cd(-) do not coexist and, second, the primary diffuser is represented by Cu-i(+)-V-Cd(-) complexes. Our results are used to discuss the effect of grain boundaries on Cu diffusion. (C) 2002 American Institute of Physics.
