ZnO/Cu2O异质结的制备及其光电性能研究
Cu2O/ZnO Heterojunction Preparation and Photoelectrochemical Performance
摘要
Abstract
The heteroj unction composed of Cu2O film and ZnO nanorod arrays was fabricated by a two-step method.ZnO nanorod arrays were firstly grown on fluorine-doped SnO2 conducting glass (FTO) by chemical solution deposition method,then Cu2O film was deposited on ZnO nanorod arrays to form heteroj unction by sequential hydrothermal method.The morphology and crystalline phase of obtained heteroj unction were characterized by scanning electron microscope and X-ray diffraction.ZnO nanorod arrays had very high purity with a (002) orientation and the length of the nanorod was around 1μm.The Cu2O film with a thickness of 1.5μm and a preferential (111) orientation grew on the ZnO nanorod arrays.Compared with the ZnO nanorod arrays,Cu2O/ZnO heteroj unction showed increased absorption intensity in the visible region.The Cu2O/ ZnO heteroj unction solar cells was observed under Sun illumination (AM 1.5,100 mW/cm2 ) with the short circuit current density (Jsc) of 7.8mA/cm2,the open circuit voltage (Voc) of 0.36V,the filling factor (FF) of 0.31,and photovoltaic conversion effciency (PCE) of 0.86%.关键词
