We have investing the effect of annealing treatment of CdO films, deposited by chemical deposition using successive ionic layer adsorption and reaction (SILAR) technique , on the film properties . The CdO thin film were Prepared by using cadmium acetate at concentration (0.03M) and base solution from ammonium hydroxide solution on glass substrate. .It's found that the optical, electrical and gas sensing (H2, CO) properties of the films are effected by the annealing temperature.

In the present paper CdO/Si heterojunction has been prepared by spray pyrolysis
method , electrical characteristics include I-V , C-V , were studied the build-inpotential
equal 1.7 eV and optoelectronic characteristics include I-V illumination
condition, photovoltaic, responsivity , quantum efficiency were studied . the
ideality factor to be 2.93 and short circuit photocurrent 170μA, open circuit
photovoltge 120mV at AM1 condition and two peaks responsivity were found ,
first peak at region 600±20nm this peak due to absorb of light in CdO through
band-to-band absorption while second region at 800±30nm which due to the Si
bandgap.
