AbstractWe successfully prepared (Cu1-XAgx)InSe2 solid solution with 0 ¡Ü x ¡Ü 1.0 by a mechanochemical process without any additional heating. The obtained fine powder was suitable for screen-printing. Particulate precursors were deposited in a thin layer by a screen-printing technique and then the porous precursor layer was sintered into a dense polycrystalline film by atmospheric-pressure firing. The crystal structures of the powder and the film were analyzed by x-ray diffraction and the microstructure of the film was observed in an SEM. For the (Cu1-XAgx)InSe2 films with x ¡Ü 0.2, the (Cu,Ag)InSe2 films had a good microstructure for the solar cell absorbers.
