“…The signal peaks at 399.11, 400.26, and 400.97 eV in the N 1s highresolution spectrum of Figure 3e respectively represent pyridinic-N, pyrrolic-N, and graphitic-N, 38 indicating the successful doping of N introduced by the aminoanthraquinone into the CNTs. The O 1s spectrum in Figure 3f contains two peaks about 532 and 534 eV, which correspond to the C�O and C−O/C−O−C bonds, respectively, 39 not only representing the successful doping of O into the CNTs but also suggesting the successful polymerization of aminoanthraquinone on the CNTs. Therefore, modified CNTs have excellent dispersion and provide the growth of SnS with many active sites, resulting in excellent specific capacity of SDC as the anode for LIBs.…”

Since petroleum resources on earth are not optimistic, developing clean energy has become a top priority. In this work, SnS@DAAQ-MWCNTs (SDC) with a honeycomb-like structure were successfully prepared by hydrothermal synthesis with SnS and carbon nanotube backbone wrapped in polymer layers as the anode for lithium-ion batteries. The electrode materials were characterized by measurements of SEM, TEM, XPS, XRD, Raman, BET, and TGA. The DAAQ-MWCNTs were found to be enhanced concerning dispersion, bringing better capacitive contribution. The SDC showed good cycling stability by CV and charge–discharge tests, demonstrating an initial discharge capacity of 762.8 mAh g–1 at 1000 mA g–1 and excellent rate performance with a recovery rate of 81.77%. This is ascribed to the special honeycomb-like structure, which enables the electrolyte to infiltrate the SDC electrode material better and swell the specific surface area for active sites.

In this review we present an overview of the different organic solar cells families. After recalling shortly the specificities of organic materials, the band structure, the electronic properties and the charge separation process in organic materials are shortly described. Then the new organic solar cell concepts are presented. Plastic organic solar cells consist either of two organic layers or a homogeneous mixture of two organic materials. One of them -either an organic dye or a semiconducting polymer -donates the electrons. The other component serves as the electron acceptor. Principles of these multi-layers and bulk heterojunctions are presented and discussed. Then some typical examples are presented, showing the fast evolution of the cells performances. Finally, a specific attention is devoted to the interfaces electrodes/organics. Indeed recent results show that, at least in the case of multi-layers cells, the introduction of thin buffer layers at the interfaces cathode/organic acceptor and/or anode/organic donor, can strongly improve the efficiency of the organic solar cells. About the interface organic acceptor/cathode, we report the influence of an exciton-blocking layer and/or an Al 2 O 3 thin layer on the efficiency of CuPc/C 60 based photovoltaic cells. The presence, or not, of a thin Al 2 O 3 layer depends on the encapsulating process of the devices. In the case of glass/ITO/CuPc/C 60 /Al cells, the presence of an Al 2 O 3 thin layer at the interface "organic acceptor/aluminium" increases strongly the open circuit voltage of the cells but decreases slightly their short circuit current and fill factor. In the case of glass/ITO/CuPc/C 60 /Alq 3 /Al cells, the open circuit voltage is systematically higher than without Alq 3 . However, in that case, the presence of Al 2 O 3 does not improve significantly the cell performances. All these results are discussed in terms of series and shunt resistance values related to possible oxygen contamination and organic covalent action with the Al films. The effectiveness of these different phenomena depends on the presence, or not, of Alq 3 and/or Al 2 O 3 layers.About the interface anode/organic donor, it is shown that an ultra thin metallic film improves significantly the short circuit current and the cell performances. The anode in plastic solar cells, which is a transparent conductive oxide (TCO), is usually an indium tin oxide film (ITO). Indeed, when a ZnO anode is used, cells performances are far from those achieved with ITO. However, strong improvement of the cells efficiency is encountered when an ultra thin buffer layer is introduced between the ZnO and the organic film. The presence of this ultra thin buffer layer at the surface of the TCO allows decreasing the performance difference between the cells using ITO and those using ZnO. More generally such ultra thin buffer layer improves the solar cells performances.

“…[5][6][7] Different functional derivatives of 9,10-anthraquinone have been synthesized and studied by various researchers. [8][9][10][11][12][13] Moreover, the electronic properties of 9,10-anthraquinones are strongly affected by the nature and position(s) of their substituent(s). The increase in electron-donating ability(ies) of the substituent(s) at various positions of 9,10-anthraquinones markedly affects the colour and redox properties of the molecules.…”

The method of computer aided vacancy migration analysis has been developed to predict the stress induced voiding (SiV) reliability. In this method, distribution of hydrostatic stress was calculated by the finite element analysis (FEA), and vacancy concentration distribution was calculated by the finite difference analysis (FDA). In this paper, SiV acceleration tests were conducted in various widths of Cu lines in organic ultralow-k dielectric (Cu/Ta/ULK/SiCN) or silicon oxide dielectric (Cu/Ta/SiO 2 /SiCN) and these results were compared with the results of the vacancy migration analyses. The number of SiV failures increased in the line with width of 0.35 m for Cu/Ta/SiO 2 /SiCN interconnects and 0.20 m for Cu/Ta/ULK/SiCN interconnects, respectively, under SiV acceleration tests. The results obtained by vacancy migration analysis show similar behavior as the results of SiV acceleration tests. These results reveal that the vacancy migration analysis is useful to predict reliability of interconnects. #
