摘要: Abstract Nanocrystalline ZnO was synthesized from zinc (II) acetate/oxalate mixture using a facile sol–gel synthesis and is characterized by techniques such as powder XRD, FTIR Raman spectroscopy, TEM SEM. The SEM study showed that the nanocrystalline film have an average particle size of 25 nm. This material has been successfully applied photoanodes in dye sensitized solar cells (DSCs) constructed with standard N719 conventional iodide/triiodide (I − /I 3 ) electrolytes. A systematic investigation performance DSCs thickness dyeing time had also carried out. Among five different thicknesses 4, 8, 12, 16 20 μm prepared, best result obtained for 16 μm 2 h dying showing efficiency 2.2% J SC 4.7 mA cm −2 very high fill factor >73%.
