Composition of zinc and cadmium have been measured for three key regions related to the formation of Cu/sub 2/S on Zn/sub x/Cd/sub 1-x/X by aqueous ion exchange. These are the ion-exchange solution, the resulting Cu/sub 2/S, and the Zn/sub x/Cd/sub 1-x/S near the Cu/sub 2/S-Zn/sub x/Cd/sub 1-x/ interface. It is found that the participation of zinc in the ion-exchange reaction is incomplete. Zinc is thus retained in the p-n junction region, and is found mainly in the Zn/sub x/Cd/sub 1-x/S just under the interface. This phenomenon helps to account for certain differences between electro-optical properties of Cu/sub 2/S/CdS and Cu/sub 2/S/Zn/sub x/Cd/sub 1-x/S solar cells.
