title: Electrochemical Infilling of CuInSe2within TiO2Nanotube Layers and Subsequent Photoelectrochemical Studies.
abstract: Anodic self-organized TiO2nanotube layers (with different aspect ratios) were electrochemically infilled with CuInSe2nanocrystals 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.
