Abstract

Anodic self-organized TiO nanotube layers (with different aspect ratios) were electrochemically infilled with CuInSe nanocrystals with the aim to prepare heterostructures with a photoelectrochemical response in the visible light. The resulting heterostructure assembly was confirmed by field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). High incident photon-to-electron conversion efficiency values exceeding 55% were obtained in the visible-light region. The resulting heterostructures show promise as a candidate for solid-state solar cells.

摘要

通过电化学方法将阳极自组装的TiO纳米管层(具有不同的纵横比)用CuInSe纳米晶体填充,目的是制备在可见光下具有光电化学响应的异质结构。通过场发射扫描电子显微镜(FESEM)、透射电子显微镜(TEM)和X射线衍射(XRD)对所得的异质结构组件进行了确认。在可见光区域获得了超过55%的高入射光子到电子转换效率值。所得的异质结构有望成为固态太阳能电池的候选材料。
