“…The heterojunction between CIS and TiO 2 nanotube layers has been utilized in several reports for the photocatalytic degradation of dyes and organic materials as well as a photocatalyst for hydrogen evolution . Within these reports, TiO 2 nanotubes have been decorated by small CIS quantum dots, nanocrystals or nanospheres utilizing SILAR technique, solvothermal technique or colloidal synthesis . The electrochemical deposition represents another viable and low‐cost approach to fill or decorate nanotubes .…”

Anodic self‐organized TiO2 nanotube layers (with different aspect ratios) were electrochemically infilled with CuInSe2 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.

“…The preparation of photocatalytic TiO 2 coatings on the substrates has been the main research direction cur-rently. A number of commonly surface techniques have been developed to synthesize titanium dioxide, such as sol-gel, chemical vapor deposition, cold spray, spray pyrolysis, and anodizing [4,5]. Micro arc oxidation (MAO) is one of the most promising and environmentally friendly technology to prepare TiO 2 coatings, which could be carried out by ultrasonic catalysis, light-ound and light-lectric combined catalysis.…”

A V-doped titania catalyst was synthesized on titanium substrate by micro-arc oxidation and then it was carried out by heat treatment in nitrogen atmosphere. The surface characteristics of the synthesized titania coatings were investigated by SEM, EDS, XPS and XRD. The synthesized TiO2 coating doped with V (in form of V2O3 and V2O5) showed a large amount of “cellular” bulges with more microscopic defects. The anatase phase of the TiO2 coatings after heat treatment tended to be transformed into rutile phase. As a result, the corrosion resistance and photocatalytic performance of TiO2 coating doped with V after heat treatment had been enhanced.

Local Electrical Response in Alkaline-Doped Electrodeposited CuInSe2/Cu Films

Abstract:The local electrical response in alkaline-doped CuInSe 2 films prepared by single-step electrodeposition onto Cu substrates was studied by current-sensing atomic force microscopy. The CuInSe 2 (CIS) films were prepared from single baths containing the dopant ions (Li, Na, K or Cs) and were studied by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy and photocurrent response. Increased crystallinity and surface texturing as the ion size increased were observed, as well as an enhanced photocurrent response in Cs-doped CIS. Li-and Na-doped films had larger conductivity than the undoped film while the K-and Cs-doped samples displayed shorter currents and the current images indicated strong charge accumulation in the Kand Cs-doped films, forming surface capacitors. Corrected current-sensing AFM IV curves were adjusted with the Shockley equation.
