  • Role of acridine orange – sodium lauryl sulphate system in photogalvanic cell for solar energy conversion

    Energy conversion efficiency was studied in liquid phase photogalvanic cell consisting acridine orange as photosensitiser, NaLS as surfactant and DTPA as reductant. Values of photopotential and photocurrent generated by this system were 746.0 mV and 205.0 µA respectively. The observed power conversion photon energy efficiency was 0.83% and fill factor was determined as 0.56. This photogalvanic ...

  • Effect of Au nanoparticles added in nanocrystalline TiO
    2
    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 ...

  • Vertically solar irradiation exergy changes in the different layers of atmosphere

    The thermodynamic characteristics of solar irradiation in the different layers of atmosphere are investigated from a perspective based on exergy. It is known that the main energy source of photovoltaic (PV) cells, solar power satellites and solar thermal devices is the solar irradiance incident on modules. To evaluate the exergy efficiency of PV cells, therefore, firstly we need the exergy of the ...

  • 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 ...

  • Electrical contacts to single nanowires: a scalable method allowing multiple devices on a chip. Application to a single nanowire radial p–i–n junction

    Semiconductor nanowires are currently at the forefront of research in the areas of nanoelectronics and energy conversion. In all these studies, realising electrical contacts and statistically relevant measurements is a key issue. We propose a method that enables to contact hundreds of nanowires on a single wafer in an extremely fast electron beam lithography session. The method is applied to ...

  • A new application of hydrogen

    A new application of hydrogen is being deployed which is helping solve humanity’s ever-evolving energy woes. Traditionally, hydrogen has a large number of applications – used in everything from industrial products to food packaging. Ammonia used in fertilizer and industrial processes amounted to 160 Million tons worldwide in 2011; hydrogen is a primary component in ammonia. The market ...

  • In Situ Biological Treatment for Soil, Sediment, and Sludge

    The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the ...

  • A Comparison Of Microbial Repair Mechanisms With Low Pressure And Medium Pressure UV Lamps

    Introduction It is well-known that bacteria and other microorganisms are capable of repairing their DNA following damage by ultraviolet (UV) radiation. Known as ‘reactivation’, it is a natural defense mechanism that has evolved over millions of years. Some microorganisms need visible light in order to repair their DNA (known as ‘photoreactivation’), while others can repair their DNA without light ...

  • The electric car: a brief history and what’s next?

    At the end of the 19th century, any vehicle not pulled by a horse or mule was considered an alternative power vehicle, powered by steam, electricity or gasoline. But oil was discovered in Texas in 1901 and by 1920, gasoline fueled internal-combustion engine vehicles dominated the marketplace. Electricity and steam powered vehicles became distant also-rans. Oil was cheap, effective, readily ...

  • Charting economic climate

    The economic climate affects our day-to-day lives. Work activities are intricately interconnected with social well-being which in turn effects family harmony and trickles on down to impact personal wherewithal. Still, 'climate' is what it is. There is nothing any of us alone can do about it. At the same time, however, how we think about it tends to shift the reality we experience day to day. ...

  • 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 ...
