摘要：

Photoluminescence (PL) and electroluminescence (EL) spectroscopy have been used on a series of chemically bevelled CdTe/CdS thin film solar cells to study the effects of different CdCl2 annealing times. An anneal time of 10 min was found to produce the most efficient (8.4%) cells. Evidence was found for the CdCl2 anneal promoting the formation of a CdSxTe1-x alloy near the interface. Emission at the back surface of the cells was identified as being due to the 'Y' luminescence band and a donor-acceptor pair (DAP) recombination involving cadmium vacancies and chlorine donors. Sulphur diffusion int the CdTe was estimated based on changes to the energy gap obtained from the PL data. (C) 2000 Elsevier Science S.A. All rights reserved.
