  • Transparent conducting oxides superstrate for thin film solar cells: an industrial prospective

    The demand for a TCO coated glass substrate as a base material and front electrode of the solar cells is expected to grow very strongly in the next few years. Therefore it is crucial to prepare the industrial tools and proper glass compositions to meet this very impressive demand. Mass production of extra clear glass and atmospheric pressure thermal CVD tool installed directly on the float glass ...

  • 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 ...


  • How do Photovoltaic Cells Actually Work?

    Solar power is an abundant renewable source that could be the solution to our future energy needs, but just how does a solar array produce the electricity that powers our lives? The short answer is that, through a solar panel, photons (light particles) are able to knock electrons off atoms and this causes a flow of electricity. The long ...

  • Photovoltaic Applications and Policy Initiatives

    Issue: The world photovoltaic (PV) market has grown significantly in recent years. Although this trend is expected to continue in the future, estimates cannot be given with any real certainty. Relevance: In this context the question that arises is the role that public and private funding plays in market development and how this funding should be used to ensure the best results. Although current ...

  • For cheaper solar photovoltaic systems

    It is known for several decades, photovoltaic devices that exploit the sun's energy to convert into electricity used to provide a sustainable alternative - and potentially unlimited - the use of fossil fuels. So why these solar technologies have they not been adopted more widely? Simply “because they are too expensive," said Ji-Seon Kim, professor of Solid Physics at Imperial College of ...

  • Photovoltaics: Basic Design Principles and Components

    If you are thinking of generating your own electricity, you should consider a photovoltaic (PV) system—a way to generate electricity by using energy from the sun. These systems have several advantages: they are cost-effective alternatives in areas where extending a utility power line is very expensive; they have no moving parts and require little maintenance; and they produce electricity ...

  • Solar Cell Production Jumps 50 Percent in 2007

    Production of photovoltaics (PV) jumped to 3,800 megawatts worldwide in 2007, up an estimated 50 percent over 2006. At the end of the year, according to preliminary data, cumulative global production stood at 12,400 megawatts, enough to power 2.4 million U.S. homes. Growing by an impressive average of 48 percent each year since 2002, PV production has been doubling every two years, making it the ...

  • Quantum dots of lead selenide: evolution of size and geometry and influence on photovoltaic effect

    Lead selenide quantum dots were synthesised by the colloidal chemical synthesis route at different reaction temperatures. The nanocrystals were characterised by X–ray diffraction (XRD), High–resolution transmission electron microscopy (HRTEM) and FTIR spectroscopy. Diameter of the PbSe quantum dots increased with reaction temperature, with average diameter varying from 30 nm to 200 nm at reaction ...

  • 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 ...

  • Optimum performance solar cells using atmospheric pressure chemical vapour deposition deposited TCOs

    High performance transparent conducting oxides (TCOs), have significance for optimising PV performance. We have developed an advanced atmospheric pressure chemical vapour deposition process, by applying fast experimentation and using a combinatorial chemistry approach to aid the studies. The deposited films were characterised for crystallinity, morphology (roughness), haze and resistivity to aid ...

  • Study of photoluminescence quenching and DC conductivity measurements in polymer-SWNT composite films for various SWNT concentrations

    Conducting polymer-SWNT composite films have a high potential in the area of photovoltaic devices and light emitting diodes (LEDs). SWNTs have high electron affinity and high mobility for electrons. As a result of this, the separation of photoinduced charges in the solar cell is very fast and efficient. For LEDs, the polymer-SWNT composite films act as efficient electron transporting layer (ETL). ...

  • 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 ...
