基于ZnO纳米片多级结构的柔性染料敏化太阳能电池的制备
Preparation of Flexible Dye-sensitized Solar Cells Based on Hierarchical Structure ZnO Nanosheets
摘要
Abstract
ZnO nanosheets/nanoparticles/microspheres composite photoanodes were synthesized in two steps. ZnO nanosheets photoanodes on Ti foil substrates were first prepared with hydrothermal synthesis method, on which ZnO nanoparticles and microspheres were deposited by using chemical bath deposition method. The corresponding photoanodes were assembled into flexible dye-sensitized solar cells (FDSSCs). Effect of Ti foil substrates pretreatment methods and chemical bath deposition process on the properties of ZnO thin films and devices were mainly studied. Phase composition and morphology of Ti foil substrates and ZnO films were characterized with XRD, SEM and TEM. J-Vcurves of the FDSSCs were tested by solar simulator and Keithley 2400.Electrochemical impedance spectroscopy (EIS) was also carried out to analyze the internal electronic transmission. The results show that when the Ti foil sub-strates were treated by using acid polishing, and the ZnO nanosheets were modified for 5 h by immersing in 0.15 mol/L methanol solution of zinc acetate after preheat treatment for 24 h, the FDSSCs displayed optimum per-formance. Its short circuit current density, open circuit voltage, fill factor and photoelectric conversion efficiency were 11.26 mA/cm2, 0.67 V, 0.60 and 4.51%, respectively.关键词
