摘要
To produce a powder as a Cu(In, Ga)Se 2 compound, for use in mono-grain membranes for solar cells, CuIn and/or CuGa alloys are prepared from Cu and/or Ga, with a hypostoichiometric Cu content. The alloys are broken down into a powder, to which is added KI or NaI. The mixture is heated to a molten state where the compound recrystalizes with a simultaneous growth of powder grains, and the molten material is cooled to interrupt the grain growth.
