The Preparation of ZnO Nanopowders and Dye Sensitized Solar Cells By Sol-gel Method
In this paper,ZnO nanopowders and dye sensitized solar cells were prepared by sol-gel and screen printing method,respectively.First,ZnO nanopowders were synthesized by using zinc acetate,ethanol and diethanolamined as raw materials.The effects of Zn2+ molar concentration on the microstructure and photocatalytic efficiency of ZnO nanopowders were investigated.When Zn2+molar concentration were 0.4M,0.6M,0.8M and 1.2M,ZnO nanoparticles with diameter of about 80~100nm were obtained.When Zn2+ molar concentration reached 2.4M,ZnO nanobowls consisted of nanoparticles with diameter about 80~100nm were synthesized.When Zn2+molar concentration reached 3.6M,ZnO nanoparticles were obtained,and particle size distribution of obtained ZnO nanoparticles became broader.Methyl orange degradation rate of ZnO nanopowders prepared with 0.4M,after treated by ultraviolet radiation for 8 hours,were up to 88.5%.ZnO nanopowders prepared with 1.2M and 3.6M were assembled into solar cells.The properties of the solar cell prepared with 1.2M were optimal.The short-circuit photocurrent,open-circuit photovoltage,fill factor and efficiency were 14.72 mA/cm2,0.649V,0.332 and 0.914%,respectively.
