Film characterisa-close-spaced vapor transport technique is used to deposit CGSe absorber. X-ray fluorescence and elastic recoil detection analysis has been carried out. Optical measurements were performed to monitor the changes in the CGSe band gap as a function of com-rements were performed to monitor the changes in the CGSe band gap as a function of composition. These results are used for a discussion of the behaviour of the ZnO/CdS/CuGaSe2 solar cell photovoltaic parameters as well as of the current transport. For the first time, a thermally activated Shockley-Read-Hall recombination mechanism is observed for the CGSe-based solar cells in a large temperature region.enArticle
