Post doctral work in Japan (At present)
Dye sensitized solar cells (DSSCs)are currently attracting acedemic and commercial intrest as regenerative low-cost alternative to conventional solid state devices. So for the best performing TiO2 nano-porous films (thickness 20-25 µm) have been prepared by simple and lowcast technique spray pyrolysis. The Pure TiO2 and ZnO, SiO2-coated TiO2 nano-porous films were deposited on FTO substrates by this method as a work electrode for the application of dye-sensitized solar cells (DSSCs). XRD pattern indicated that Pure TiO2 and ZnO, SiO2 coted TiO2 shows the same structure. The FE-SEM and EDAX analysis gives an information about that the surface morphology and the existance of ZnO and SiO2 on the surface of the TiO2 films as a layer, respectively. The photoelectrochemical (J-V curves) values of DSSCs for pure TiO2 films and ZnO, SiO2-coated TiO2 nano-porous thin films were studied and compared. These results shows that the short-circuit photocurrent (Jsc) and open-circuit voltage (Voc) values of pure TiO2 increased from 0.70 V to 0.718 V, 0.74 for SiO2 , ZnO-coated TiO2 nano-porous thin films based cells, respectively. The current density of the pure TiO2 changed from 16.73 mAcm-2 to 18.92, 18.09 mAcm-2 for SiO2, ZnO-coated TiO2 nano-porous films respectively. The efficiency of the cells has been grately improved appreciably from 8.25% to 9.1, 9.32 % for SiO2 , ZnO-coated TiO2 nano-porous films based cells. This results indicated that the DSSCs with SiO2 , ZnO-coated TiO2 nano-porous films contributed to provide an inherent energy barrier that suppressed charge recombination significantly. The Impedance studies reveals that the chrage tranfer resistance of the cell was highly decreased by the coating of ZnO as well as SiO2 on the surface of the TiO2.
Polymer gel-electrolytes were prepared by based on 1, 3 dimethyl 3-propyl dimidazolium iodide (DMPII) and based on ionic liquids BMII (Hexyl, propyl) and studies their performance in solar cells.In our present investigation we study the photoelectrochemical characteristics of titanium dioxide (TiO2)-based dye-sensitized solar cells (DSSCs) containing gel polymer electrolyte (GPE) based on PAN and organic liquid electrolyte (OLE) were prepared by hotpressing method. polymer gel electrolytes were characterised by X-ray diffraction (XRD) and field emision electron microscopy (FE-SEM). The conductivity of the gel electrolytes was determined by impedance studies. A polymer gel electrolyte with ionic conductivity of 8.67mS cm-2 was measured by poly (acrylonitrile) as polymer matrix, acetonitrile and tetrahydrofuran as binary organic mixture solvent, LiI + I2 as electrolyte, activated carbon powder and 1-N-butyl-3-hexyl imidazolium as additives. The components ratio of the polymer gel electrolyte was optimized, and the influence of the components and the ionic conductivity of the polymer gel electrolyte was investigated. On the basis of the polymer gel electrolyte with the activated carbon, a quasi-solid-state dyesensitized solar cell was fabricated and its lightto- electricity energy conversion efficiency of 6.55 % was achieved under irradiation of 100 mW cm-2.
Work experience as a post doc researcher in china
The cathode electrode films of MoO3 and V2O5 nanobelts, nanotubes and nanowires are synthesized by hydrothermal method and intercalated with PEO, PANI and PEG polymers. These cathode materials are investigated through X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FTIR) studies. To investigate the thermal stability and morphology of the samples Differential Scanning Calorimetry (DSC), (TG) curves and Scanning Electron Microscopy (SEM) are used. Chemical stoichiometry of the elements in the electrode materials are estimated qualitatively and quantitatively using XPS analysis. TEM, HR-TEM and SAED are used to determine the dimensions and structure of these electrode materials. The Electrochemical batteries were assembled in a dry glove box filled with argon using lithium pellets as a negative electrode. Then the cell performance such as specific capacity, current density and discharge stability is evaluated using Battery testing machine, cyclic voltmeter (Gpes). Electrochemical impedance spectroscopy was carried out using frequency response analyzer (FRA). Xerogel of V2O5 and MoO3 mixed with various polymers like Poly ethylene oxide (PEO), poly anilline (PANI) prepared via sol gel and hydrothermal treatments. Electrochemical and electro chromic properties at different potentials were studied. Electrical Conductivity and electrochemical properties were studied.
Lithium ion-conducting solvent-free nanocomposite solid polymer electrolyte films were prepared based on Poly Vinyl Alcohol (PVA) polymer using solution casting technique. In this technique, nanoinsulating particles such as Al2O3, and TiO2 will be incorporated into the PVA complexed with lithium salt (LiAsF6). Using XRD, FTIR are used to determine the structural properties. Thermal stability was determined using differential scanning calorimetry (DSC).
AC conductivity was calculated from Impedance plots (Cole-Cole) Z’vs Z” and percolation threshold was estimated for three composition system. Transference number measurements were carried out to investigate the nature of charge transport in these composite polymer electrolyte systems by the combination of AC and dc polarization methods. Optical band gaps (both direct and indirect) and band edge values were determined using optical absorption data
The dielectric relaxation spectroscopy (dielectric loss vs Frequency, dielectric permittivity vs frequency at different temperature was used to realize the microscopic dynamical relaxation process in these polymer composite materials. Finally, the electrochemical cell with the configuration of Li/ Composite Polymer electrolyte/(Cathode) will be fabricated using these nanocomposite polymer electrolytes films and nanocathode materials. The cell performance will be evaluated using cyclic voltmeter and impedance analyzer.

Anode-Platinum, Cathode-Brass, current density and duration were varied.
Experiments were carried out in DC and Pulse power supply. In pulse plating duty ratio, peak current density, and average current density were set. Pulse plating experiments were done using Pulse power supply instruments which had high end electronic system.
Grey smooth coating was obtained. No pits. Dendrites were formed at higher current densities. Samples were sent to XRD, hardness analysis.
2. Cobalt-Nickel co-deposition :
Co-Ni alloy were deposited on Mild steel samples. The first experiment was done without Co content in the bath. And in the series of experiments, the concentration of Cobalt sulphamate was gradually increased till a smooth coating with stress free coating was obtained.

Substrate-Mild steel, Anode-Nickel, temperature-45C.
The PH of 4.0 gave hydroxide coating, so PH was reduced to 2.5. Grey smooth deposits were formed. A few samples had pits. The hardness of the coatings increased as the concentration of Cobalt sulphamate increased in the plating bath. The colour of the coating was darker with the increase of Cobalt sulphamate. A maximum hardness of 480 HV was obtained when the concentration of Cobalt sulphamate was 30ml/l. EDX report revealed 25 percent Co and 75 percent Ni. The samples were sent to XRD.
3. Solar Selective Coating :
