CdSe, mainly, and Cd(Se, Te) alloy layers were cathodically electropla
ted onto titanium, nickel and (100) oriented nickel substrates from an
acid sulphate solution at 85 degrees C. The growth of the deposits, o
n Ti and Ni, was partly controlled by altering the mode of the nucleat
ion first step. This procedure, though inhibiting the establishment of
a strong crystal orientation, seems to positively affect the photocon
version efficiency of the CdSe films on Ni. Crystallized deposits with
defined stoichiometry are obtained on (100) oriented Ni cathodes alon
g a narrower, than the typical case. range of electrolysis potentials.
The polycrystalline films are always cubic and the measured photoconv
ersion efficiencies reach 2.6%.
