ABSTRACT = {Photoconductive possessions through the highly sensitive and responsive in lower 
applications apply voltages with a charge that effect the product for the photodetector 
utilizing Copper Sulfide was effective to fabricate and deposit by the means of thermal 
evaporation techniques following by the heat treatment with applications as the visible 
photodetector was described. Effects of doping to the antimony and aluminum on photo 
detectors property were estimated to be below illumination by the utilization of different 
power densities. The structure with the surface morphology properties was studied by 
XRD and AFM techniques, a clear effect of dopant on absorption coefficient and energy 
gap was found in examination of the optical transmit, the device photocurrents property 
under reverse bias by utilizing several illuminations had been tested, moreover the high 
responsivity of Cu<sub>2</sub>S: Al/Si photo detectors was around the wavelength of 751 nm, 
quantum efficiency besides the detectivity had been evaluated for every sample, the values 
of responsivity by the help of doping has risen which is required for good photodetectors 
application.},
