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...

An important problem in synthetic biology is to design a nucleotide sequence of an mRNA that confers a desirable expression level of a target protein. The secondary structure of protein-coding sequences (CDSs) is one potential factor that could have both positive and negative effects on protein ...
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...
"Giant" semiconductor quantum dots (GQDs) have tremendous potential for applications in laser devices. Here, CdSe/CdS core–shell GQDs (11 monolayers) have been synthesized as lasing gain material. The photoluminescence decay of the GQD ensemble is single-exponential, and the two-photon absorption...
Thin films of CdS were prepared from an solution containing Cd(Ac)2, NH4OH, NH4Ac and (NH2)2CS for solar cells. Growth rate of CdS films was increased with increasing temperature of reactive solution and with decreasing concentration of NH4OH. Optical transmittances were more than 60% independ...
We have used the MR-CAT beam-line of the Advanced Photon Source (APS) at Argonne National Laboratory to study Cu x-ray fluorescence (XRF) in CdS/CdTe/Au structures on fused silica without transparent conductive oxide (TCO). After a "peel-off" process that separates the back contact at th...
Due to the limited operational environment of WMNs, an efficient connected dominating set(CDS) construction scheme is an important concern since it has been found extremely useful in broadcasting, routing and virtual backbone construction. In this paper, we propose a distributed Bandwidth-Interference ...
摘要: Temperature (T) dependence of photoluminescence spectra of laser ablated CdS films are presented. The analysis of spectral position and line width of the excitonic line versus T allows to calculate the critical parameters of CdS films.关键词: photoluminescence semiconductors thin films ...
