CuInSe2 (CISe) is a prototype material for the I-III-VI chalcopyrites such as Cu(In,Ga)(S,Se)(2) used as absorber layers in thin film photovoltaic cells. Carefully-controlled pulsed-laser annealing (PLA) is a unique annealing process that has been demonstrated to improve the device performance of chalcopyrite solar cells. Here, we investigate the changes in defect populations after PLA of electrochemically-deposited CISe thin films previously furnace annealed in selenium vapor. The films were irradiated in the sub-melting regime at fluences inducing temperatures up to 840 +/- 100 K. Deep-level transient spectroscopy on Schottky diodes reveals that the activation energy of the dominant majority carrier trap changes non-monotonically from 215 +/- 10 meV for the reference sample, to 330 +/- 10 meV for samples irradiated at 20 and 30 mJ/cm(2), and then back to 215 +/- 10 meV for samples irradiated at 40 mJ/cm(2). A hypothesis involving competing processes of diffusion of Cu and laser-induced generation of In vacancies may explain this behavior. Published by Elsevier B.V.
