Fabrication of CdS/CdTe solar cell is the promising research field in the world. This study, introducing and intermediated ultra-thin CdTe nucleation layer by electrodeposition technique (ED-CdTe*), between the CBD-CdS window layer and CSS-CdTe absorber layer. Thus, it eliminates the recombination mechanism in the depletion region, and reducing pinholes formation, and creates better contact between CSS-CdTe heading to improve the efficiency of the device.  The efficiency of the glass/FTO/CBD-CdS/CSS-CdTe and glass/FTO/CBD-CdS/ED-CdTe*/CSS-CdTe was improved from 14.6% to 15.6% in the presence of the nuleation layer.
