Developing Silicon Solar Cell by Doping ZnO with Several Metallic Elements - تطوير اداء خلية سليكونية مصنعة بطريقة تطعيم أوكسيد الزنك ببعض العناصر المعدنية

Abstract

The structural and optical properties of pure (ZnO and Au , Ag , Cu) doped thin films with doping ratio (3%) , have been prepared by thermal evaporation technique on glass substrate of (300 nm) thickness at room temperature, have been studied. Both the structural and optical measurements were carried out as deposited and doped films. )XRD( spectra revealed that all films have polycrystalline structure except that doped with Cu it has one significant sharp peak at (2Ө=36.4°). The results of the optical studies showed that the optical transition is direct allowed. The energy gap in general decrease as with doped (Au, Ag, Cu) dopant elements respectively.
