Four new bis(tpy) unimers with different linkers between the thieno[3,2-b]thiophene-2,5-diyl central unit and terpyridine-4′-yl (tpy) end-groups: no linker (Tt), ethynediyl (TtE), 1,4-phenylene (TtPh) and 2,2′-bithophene-5,5′-diyl (TtB) are prepared, characterized, and assembled with Fe2+ ions to metallo-supramolecular polymers (Fe-MSPs). The Fe-MSP films prepared by spin-casting on Indium Tin Oxide (ITO) glass are characterized by atomic force microscope (AFM) microscopy, cyclic voltammetry, and UV/vis spectroscopy and studied for their electrochromism and effect of the unimer structure on their electrochromic performance. Of the studied MSPs, Fe-Tt shows the highest optical contrast as well as coloration efficiency (CE = 641 cm2 C−1) and the fastest optical response. This makes it an excellent candidate for possible use in electrochromic devices.

In this work, we implemented liquid exfoliation to inkjet-print two-dimensional (2D) black phosphorous (BP) and molybdenum disulfide (MoS2) p–n heterojunctions on a standard indium tin oxide (ITO) glass substrate in a vertical architecture. We also compared the optical and electrical properties of the inkjet-printed BP layer with that of the MoS2 and the electrical properties of the mechanically exfoliated MoS2 with that of the inkjet-printed MoS2. We found significant differences in the optical characteristics of the inkjet-printed BP and MoS2 layers attributed to the differences in their underlying crystal structure. The newly demonstrated liquid exfoliated and inkjet-printed BP–MoS2 2D p–n junction was also compared with previous reports where mechanically exfoliated BP–MoS2 2D p–n junction were used. The electronic transport properties of mechanically exfoliated MoS2 membranes are typically better compared to inkjet-printed structures but inkjet printing offers a cost-effective and quicker way to fabricate heterostructures easily. In the future, the performance of inkjet-printed structures can be further improved by employing suitable contact materials, amongst other factors such as modifying the solvent chemistries. The architecture reported in this work has potential applications towards building solar cells with solution processed 2D materials in the future.

This study describe the effect of temperature on the opticalproperties of nickel(ii) phthalocyanine tetrasulfonic acid tetrasodiumsalt (NiPcTs) organic thin films which are prepared by spin coatingon indium tin oxide (ITO-glass). The optical absorption spectra ofthese thin films are measured. Present studies reveal that the opticalband gap energies of NiPcTs thin films are dependent on theannealing temperatures. The optical band gap decreases with increasein annealing temperature, then increased when the temperature risingto 473K. To enhance the results of Uv-Vis measurements and getmore accurate values of optical energy gaps; the Photoluminescencespectra of as-deposited and annealed NiPcTs thin films was studied.FTIR measurements for NiPcTs thin films also carried out in thiswork and gave good information about the NiPcTs bonds and itslocations as a compared with H2Pc as a reference.

Improved Stability

Efficiency and stability are the main challenges of organic solar cells. In this research novel structure is investigated for organic solar cell which has improved efficiency and improved stability. Blend of PTB7 and PCBM elements was used for the active layer of cell. Thickness of this layer was varied from 80nm to 200nm and selected the optimized thickness of 90nm. On which the cell has maximum efficiency of 12.24 %. The influence of window layer material such as Zinc oxide (ZnO) and titanium dioxide (TiO2) with various electrode materials including Indium tin oxide (ITO), Fluorine tin oxide (FTO), aluminum (Al) Silver (Ag) and Gold (Au) with different combinations have been investigated with the objective to enhance the absorption and PCE of the cell. Also varied the thicknesses of these different layers and selected the optimized thickness on which the cell had maximum efficiency. The structure of the proposed scheme was observed with ITO/Al as top and bottom electrode with thicknesses of 125nm and 100nm respectively and found that this holds the highest performance parameters including Jsc=0.130(mA/m2), Voc= 1 (V), FF=94.1% and ƞ=12.24% respectively as compared to different electrode combination and window layers with the same photoactive absorber material PTB7: PCBM. This indicates that the proposed structure can be a good choice for replacing less efficient in-organic cell.

Hydrogen Peroxide Detection

The nanoporous Co 3 O 4 thin films were prepared on indium tin oxide (ITO) glasses by an electrodeposition method. The surface morphology and composition of the nanoporous Co 3 O 4 films were characterized by scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDS) and X-ray photoelectron spectroscopy (XPS). The results show that the as-deposited nanoporous Co 3 O 4 film is constructed by many interconnected nanoflakes with thickness of about 40 nm. The cyclic voltammetry (CV) measurement indicates that the nanoporous Co 3 O 4 films exhibit remarkable electrocatalytic activities for the hydrogen peroxide ( H 2 O 2) reduction which shows that it is a good candidate to be employed as electrode materials for electrochemical sensing of H 2 O 2. Further analysis indicated that the detection sensitivity of the sensor was 1.357 mA mM-1 cm-2 and the detection limit was estimated to be about 0.2 mM.
