Thin Film Solar Cells Novel Approaches by Different Method of Techniques
In these approaches of research articles is giving my review of work, ZnO thin films were derived by sol-gel using two method of techniques; dip coating and spin coating technique. The films through deposited onto glass substrate at room temperature using sol-gel composed from zinc acetate dehydrate, ethanol alcohol, and de-ionized water, the films were preheated at 225?C for 15 min.The crystallographic structures of ZnO films were investigated using X-ray diffraction (XRD) and scanning electron microscopy; the result shows that the good film was preparing at dip-coating technique, it was polycrystalline and highly co-orientation along (002) plane. The structure of thin films, prepared by dip-coating technique method have good transmittance of about 92% in the visible region, it can be noted from the fluorescence spectrometer two broad visible emission bands entered at 380 nm and 430 nm.
