CdTe-based solar cells have long been of interest for terrestrial usage because of their high potential conversion efficiency (in the range of 18–24%) with low-cost manufacturability and concern over environmental effects . In order to conserve material and address environmental pollution concerns as...
The resistivities of CdS were decreased by doping boron from 104to 101order(Ω - cm) and the critical amount of dopant was 5 × 10−.mol % 展开 关键词: solar energy materials science cadmium sulfides chemical coating cadmium sulfide solar cells optical properties phase studies electric ...

These CdSexS1-x QD-sensitized 3D-TiO2-HNs were then used as photoelectrodes in the preparation of quantum-dot-sensitized solar cells. As revealed by TEM images, the highly porous 3D-TiO2-HNs represent an excellent framework on which to deposit a large number of CdSexS1-x QDs in order ...
Polycrystal films were prepared by coating slurry on amorphous glass substrates and sintering in a nitrogen atmosphere in an attempt to produce films with properties suitable for fabricating all﹑olycrystal heterojunction solar cells. The uniformity in microstructure and properties of these films has been...

The broad-spectrum J-V data was fit to a parallel diode model in order to extract diode parameters. Analysis reveals the existence of two junction transport mechanisms. The first is an intensity-independent recombination process, dominant at high bias levels under low illumination intensity. The ...
In order to locate the Cu spatially, we prepared TEM cross-sections and performed analytical electron microscopy at the Electron Microbeam Analysis Laboratory (EMAL) at the University of Michigan, to obtain high-resolution electron microscopy (HREM) imaging with a point-to-point resolution of 1.7 ...
CdCl2, CuCl2 and propylene glycol on a glass substrate and sintering in a nitrogen atmosphere, to investigate the effects of copper doping on the window properties of all-polycrystalline CdS/CdTe heterojunction solar cells. The variations of carrier concentration as a function of the amount of cop...
Our CDS construction scheme selects the node that has more neighbors and enough bandwidth to support more end-devices in order to enhance overall network throughput and reliability. We confirm through simulations and show that our scheme constructs the CDS with the small subset of DS and the ...
