Abstract

Selenization growth o± purely single-phase, polycrystalline CuIn1-xAlxSe2 (0 ≤ x ≤ 0.26) alloy films was demonstrated using a less-hazardous metal-organic selenide, diethylselenide [(C2H5)2Se: DESe]. Without additional thermal annealing, approximately 2.0-μm-thick alloy films exhibiting X-ray diffraction peaks originating exclusively from the chalcopynte structure were obtained. Their low temperature photolumi-nescence spectra were dominated by characteristic donor-acceptor pair emissions usually seen in the state-of-the-art CuInAlSe2 photoabsorbing layers.
