The samples were either measured as-grown or after thermal treatment in an oxygen containing ambient with and without the chlorine containing compounds such as cadmium chloride, hydrochloric acid, and sodium chloride. The as-grown sample is discussed in detail, in order to then demonstrate the changes in the PL spectra induced by the postdeposition treatments. A deep level transition at 1.32 eV was observed in the as-grown sample which can be correlated with cadmium vacancies. Due to postdeposition treatments this deep level transition disappears and a broad band correlated with A-centers arises instead at about 1.43 eV. Another transition band at 1.479 eV in the as-grown sample is not influenced by any postdeposition treatment. Furthermore, by processing solar cells out of the respective samples, the PL results can be related to the solar cell parameters.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Publication:<\/b> 2010<\/p>\n","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"beteiligte":[],"class_list":["post-2650","publikationen","type-publikationen","status-publish","hentry","publikationen_category-inorganic-chemistry","publikationen_category-physical-chemistry"],"acf":[],"_links":{"self":[{"href":"https:\/\/forschungsnetzwerk-chim.de\/en\/wp-json\/wp\/v2\/publikationen\/2650","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/forschungsnetzwerk-chim.de\/en\/wp-json\/wp\/v2\/publikationen"}],"about":[{"href":"https:\/\/forschungsnetzwerk-chim.de\/en\/wp-json\/wp\/v2\/types\/publikationen"}],"wp:attachment":[{"href":"https:\/\/forschungsnetzwerk-chim.de\/en\/wp-json\/wp\/v2\/media?parent=2650"}],"wp:term":[{"taxonomy":"beteiligte","embeddable":true,"href":"https:\/\/forschungsnetzwerk-chim.de\/en\/wp-json\/wp\/v2\/beteiligte?post=2650"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
