Synthesized pure and Ag-doped ZnO nanostructures using a simple co-precipitation method and applied them onto Si substrates. Studied the evolution of nanostructure and opto-electronic characteristics in doped layers with different Ag content. Examined crystal structure and surface morphology of deposited films using XRD and AFM techniques. Investigated surface passivation quality using FTIR and photoconductance-based techniques to understand electronic and optical losses. Lifetime values increased from 1.5 to 106 μs at a density of 5.10(14) cm(-3) according to photoconductance lifetime measurement, while reflectivity decreased from 36% to 6% after deposition of Ag:ZnO on silicon surface.
Synthesized pure and Ag-doped ZnO nanostructures through a simple co-precipitation method, which was then applied onto silicon (Si) substrates using a spin-coating technique. The nanostructure and opto-electronic characteristics evolution of elaborated layers doped with different Ag content was studied. The crystal structure and surface morphology of the deposited films were investigated using XRD and atomic force microscopy (AFM) techniques. The surface passivation quality is determined by employing FTIR and photoconductance-based techniques, according to research on the evolution of electronic and optical losses in the silicon top surface. Lifetime values determined by photoconductance lifetime measurement show an increases from 1.5 to 106 & mu;s at the density (n) of 5.10(14) cm(-3). However, the reflectivity given by UV-Vis results demonstrate a decrease from 36 to 6% after the deposition of Ag:ZnO on silicon surface.
