Abstract
Crystals of CdSxSe1-x where 0 x 1 are produced by evaporation from three individual crucible containing Cd, Se and S and condensation in ceramic or glass receiving vessel under high vacuum. REceiving vessel temp. is maintained at 120-400 degree sC., and the above compn. is achieved by varying crucible temp. of S with respect to Se whilst maintaining Cd crucible temp. constant. Crystal layers are used in solar cells.
