摘要

光伏技术在替代化石燃料资源方面具有很大的潜力，但仍存在器件制造成本高的问题。在此，我们试图用非均质纳米结构来解决这些问题。首先，采用简便的制备方法制备了氧化锌(ZnO)/氧化钴(Co3O4)异质结纳米线。通过在ZnO纳米线阵列上组装Co(OH)2纳米片，在ITO涂层玻璃和硅片上均匀合成了ZnO/Co3O4非均相纳米结构。通过导电原子力显微镜测量电流(I)-电压(V)，显示出优异的光伏效应。异质结纳米结构具有前所未有的高开路电压。因此，证明了非均质纳米结构在太阳能电池中的潜在应用。

Facile Hydrothermal Preparation of ZNO/CO3O4 Heterogeneous Nanostructures and its Photovoltaic Effect

Photovoltaic technology offers great potential in the replacement of fossil fuel resources, but still suffers from high device fabrication cost. Herein, we attempted to provide a solution to these issues with heterogeneous nanostructures. Firstly, Zinc oxide (ZnO)/cobalt oxide (Co3O4) heterojunction nanowires are prepared through facile fabrication methods. By assembling Co(OH)2 nanoplates on ZnO nanowire arrays, the ZnO/Co3O4 heterogeneous nanostructures are uniformly synthesized on ITO coated glass and wafer. Current (I)-voltage (V) measurement through conductive atomic force microscope shows excellent photovoltaic effect. And, the heterojunction nanostructures shows unprecedented high open circuit voltage. Therefore, the potential application of the heterogeneous nanostructures in solar cells is demonstrated.
