This paper presents photoelectrochemical properties of multi-walled carbon nanotube assembled with CdSe quantum dots. CdSe QDs are adsorbed on the surface of MWCNTs with a diameter of 4-5 nm.
In this paper, fabrication and characterization of QDSSCs based on CNT doped TiO2 mesopores film were reported. The improved efficiency is obtained for the device using CNT/TiO2/CdSe as the photoanode. The QDSSCs based on bare TiO2 and CNT doped TiO2 were named as sample A and B.
Summary form only given. CdS is a promising material for flat panel displays, light-emitting diodes, lasers, logic gates, and transistors. CdS has attracted special interest because it exhibits high photosensitivity and its band gap energy (2.41 eV) and electron affinity (4.5 eV) appear in the visible spectrum [1]. In this work, CdS deposition on surface of the vertical aligned carbon nanotube (VACNT)...
Summary form only given.Recently, there is an increased interest in quantum dot sensitized solar cell (QDSSC), i.e., applying semiconductor quantum dots (QDs) in dye-sensitized solar cells [1]. However, QDSSCs have shown comparatively lower efficiencies than expected. One possible reason for the poor efficiency of QDSSC is the difficulty of assembling the QDs on ZnO surface to obtain a well-covered...
We report on 2D numerical simulations of laser beam induced current (LBIC) for HgCdTe photovoltaic detector. The effect of junction leakage current on the LBIC signal is investigated, and different leakage paths caused by different reasons in HgCdTe photodiode arrays are taken into account in the simulation. The simulation results are in good agreement with the experiment data. Simulation results...
The behavior of transition metals in ZnO has become an important topic for spintronics. As the fundamental property, the nano-structural characteristics of the transition metal implanted ZnO have been studied. It is clearly observed that in ZnO the Mn+ implantation and post-annealing result in (1) the formation of crystallographically orientated Zn nanocrystals within the ZnO matrix and (2) Mn atoms...
