We study the growth of Cu films en route to the production of CuInSe2 thin
films as absorber layers in solar cells by a low pressure chemical vapor de
position technique. In order to obtain good quality films, the deposition c
onditions such as substrate, source temperatures, concentration ratio of Ar
to H-2 have been optimized. The surface morphology and structural analysis
of Cu films have been carried out. It is revealed that annealing resulted
in a change in the properties of the films and also in the generation of ot
her phases such as gamma-Cu5Si (cubic) and CuO (monoclinic). (C) 1999 Kluwe
