摘要：

TiO2 film materials have very wide applications in photovoltaic conversion techniques. And, TiO2 nanotubes array film with nanowires directly formed on top (denoted as TiO(2)NTWs) was prepared by the anodization method. CdS and PbS quantum dots (QDs) were firstly cosensitized on the TiO(2)NTWs array (denoted as (CdS + PbS)/TiO(2)NTWs) by novel successive ionic layer adsorption and reaction (N-SILAR), which only needed a cation mixed solution containing Cd2+ and Pb2+ and an anionic solution containing S-2. This N-SILAR method can not only effectively shorten the experimental time, simplify the experiment procedure and reduce the experiment cost, but also make the material of (CdS + PbS)/TiO(2)NTWs possess the advantages of improving electron transport and reducing chemical erosion. Moreover, the photocurrent of (CdS + PbS)/TiO(2)NTWs was 4.1 mA/cm(2) under an illumination of 100 mW/cm(2). The most eye-popping part was that the result was 8 times higher than that of the bare TiO(2)NTWs array. The result of photoelectrochemical measurements indicated that this novel material had a potential application in photovoltaic devices. (C) 2014 Elsevier B.V. All rights reserved.
