Abstract
AbstractIn this work, the synthesis of zinc oxide (ZnO) and silver-doped zinc oxide (Ag-ZnO) and its application in dye-sensitized solar cell (DSSC) have been described. For the synthesis of ZnO and Ag-ZnO, inexpensive and versatile chemical co-precipitation method was used. The X-ray diffraction (XRD), UV–Visible (UV–Vis), and scanning electron microscopy (SEM) were utilized to characterize the synthesized ZnO and Ag-ZnO. These synthesized materials were employed in DSSC as n-type layer in conjugation with ruthenium-based dye (N719). The photovoltaic (PV) parameters of ZnO and Ag-ZnO-based DSSC were obtained by current–voltage measurement. The result showed that the power conversion efficiency (PCE) of Ag-ZnO-based (2.77%) DSSC was improved as compared to pure ZnO-based DSSC (2.39%).KeywordsAg-doped ZnODye-sensitized solar cellChemical co-precipitation
