    film on the photoelectrode of dye–sensitised solar cells

    In this study, we used a citrate reduction method and electrophoretic deposition (EPD) to prepare hybrid nanocrystalline TiO2/Au films and applied it to the photoelectrode of dye–sensitised solar cell. The films and solar cells were investigated by field emission scanning electron microscopy (FE–SEM), energy dispersive X–ray analysis (EDX), X–ray diffraction (XRD), I–V ...

  • Water vapour permeation measurement for PV Solar Cell packaging

    With fears of carbon dioxide causing global warming and diminishing supplies of fossil fuels, a looming energy crisis is affecting all countries.  As a consequence, a great deal of world-wide effort is going into the development of alternative energy technologies.  At present, wind, hydro and geothermal are becoming well established with more niche roles for tidal and solar. The latter ...

  • Researchers explain how dye-based nanotubes can help harvest light’s energy

    Tiny cylinders help reveal how natural-light-harvesting antennae collect light with exceptional efficiency. Written by David L. Chandler, MIT News Office.You can read the original new in MIT NewsCompanies that make commercial solar cells are happy if they can achieve 20 ...

  • Solar`s Time to Rise and Shine.

    Photovoltaic efficiency records are being shattered, thanks to recent advances in materials science. Last month, a researcher at the National Renewable Energy Laboratory in Golden, Colo., loaded a postage stamp–sized solar cell onto a tray and placed it under a high-intensity pulse solar simulator. The simulator flashed a 2.5 millisecond pulse of light, and 19 mirrors reflected the ...

  • Thin film technologies changing the solar PV business

    The solar photovoltaic (PV) industry is clearly in a rapid growth phase. The worldwide industry size was recently estimated at US$50 billion. Over the past few years, production capacity is thought to have grown at an average of 48% each year and cumulative global production is now at 12.4 Giga Watts (GW). It is also an industry on the brink of change. New technologies are emerging that seem ...


  • Comparative study of TiO 2 films prepared by EPD and sol-gel techniques and their use in DSSCs

    In this work, we give a comparative study of titanium dioxide (TiO 2 ) films fabricated using the electro-phoretic deposition technique (EPD) and the sol-gel one. The TiO 2 films were elaborated on commercial ITO layers and were used as photo electrodes in dye sensitised solar cells (DSSCs). To fabricate these cells, we used N 3 as the sensitising dye, the electrolyte is a ...

  • Highly crystalline hydrothermal ZnO nanowires as photoanodes in DSCs

    Vertically aligned ZnO nanowires (NWs) were prepared inside an autoclave by a hydrothermal procedure at temperatures above 100°C (HP). The effects of synthesis temperature and time on the morphology of ZnO NWs were carefully studied. The performance of HP ZnO NWs was compared with that of ZnO NWs grown by a conventional ambient pressure hydrothermal method at temperatures below 100°C (LP) ...

  • Effect of seed particle size and ammonia concentration on the growth of ZnO nanowire arrays and their photoconversion efficiency

    ZnO nanowire arrays were synthesised for dye-sensitised solar cell applications using the chemical bath deposition technique. To study the effect of the particle size in the seed layer on the growth and resultant photoconversion efficiency, we prepared various seeded FTO substrates by repeating the seed layer sol-gel coating process. It was found that changing the number of coating process ...

    pastes for DSSCs application

    Ethyl cellulose (EC)–based TiO2 pastes were prepared in order to fabricate flat and crack–free TiO2 films employing screen–printing technique. Pure anatase TiO2 was synthesised via hydrothermal process using titanium (IV) n–butoxide as Ti–precursor and peptised by acetic acid. The as–prepared ...

    electrode and poly(N–methyl 4–vinylpyridine iodide): ionic liquid solid polymer electrolyte for device application

    The aim of this work is to synthesise a porous nanocrystalline TiO2 electrode and a new kind of solid polymer electrolyte poly(N–methyl 4–vinylpyridine iodide) (PVPI) doped with an Ionic Liquid (IL) 1–ethyl 3–methylimidazolium thiocyanate (EMImSCN) for Dye–Sensitised Solar Cell (DSSC) application. The fabrication process of nanoporous ...

    nanowires on transparent conducting oxide substrate

    TiO2 nanowires were synthesised directly on FTO by solvothermal method. X–ray diffraction (XRD), field–emission scanning electron microscopy (FE–SEM) and high–resolution transmission electron microscopy (HRTEM) were used to characterise the TiO2 nanowires. The TiO2 nanowire formation was critically ...

  • Prompting electron transport in mesoporous semiconductor electrode by simple film compression

    Tuning materials packing in the photoanode films through a simple cold isostatic pressing (CIP) post-treatment allows highly efficient charge transport and a dramatically retarded recombination that are witnessed by electrochemical impedance spectroscopy (EIS) studies. The pressing post-treatment produces densely packed TiO 2 nanoparticle film with fewer relatively large vacancies and better ...

  • Solution processing of conducting dense and porous films; doped ZnO and TiO2, and perovskites

    Solution based processing of porous and dense films by all-alkoxide based precursor systems have been investigated and compared, with a focus on the connection between the precursors and heat-treatment, and the product oxide quality and structure. Three systems were investigated typically with TGA, DSC, XPS, IR spectroscopy, X-ray diffraction, TEM-EDS and SEM-EDS, but also with other advanced ...

  • SolarBee Technical Bulletin

    A. SOLARBEE OVERVIEW 1. Origin of the SolarBee. Pump Systems, Inc. (PSI) developed, built and installed its first solar powered mixer in Dickinson, ND, in the summer of 1998. It was installed into a 30 acre x 13 foot deep municipal wastewater reservoir which had a long history of toxicity associated with ammonia, odor, and stratification problems. In six weeks the entire reservoir cleared up to ...
