(JP2000058893-A)   NOVELTY - The process involves preparing a source material including oxide-containing particles including Group IB and IIIA elements, depositing the source material on a base to form a film, heating the film in a suitable atmosphere to form a precursor film including non-oxide Group IB and IIIA elements, and providing a suitable material to the precursor film including a Group IB-IIIA-VIA compound.    USE - Solar cell and other electronic device manufacture.    ADVANTAGE - The compound film has greater uniformity and compositional control and superior electronic properties. Enables production of solar cells having conversion efficiencies close to or above 10%.
