  • Photovoltaics Energy Technologies

    Technology Overview    Photovoltaic (or PV) cells are devices that use semiconductor materials—similar to those used in computer chips—to convert sunlight directly into electricity. The electric current can either be used immediately, or it may be stored, as in a battery, for later use. A typical PV or solar cell might be a square that measures about 4 ...

  • 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 ...

  • 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 ...

  • Towards high efficiency solar cells with new material

    While previous developed materials aimed at high efficiency used several junctions of indiumgallium- nitride (InGaN) with different proportions of indium and gallium side by side to cover a wider solar light spectrum, the newly developed solution treats a zincmanganese-tellurium (ZnMnTe) alloy in such a way that a single junction is able to have a photovoltaic response to almost the entire solar ...

  • Transparent conductive oxide materials: financial stakes and technological challenges

    Although transparent conductive oxides (TCOs) have been known and used for quite some time, research on these materials is still very active to improve their characteristics. This paper is aimed at giving an overview of the contribution of the TCO materials to the economy in various fields of applications (flat panel displays, photovoltaics, light-emitting diodes, smart windows, gas sensors, ...

  • The Water-Energy Nexus

    Different types of electricity generation require differing amounts of water. Except for photovoltaic solar and wind power, which require no water to produce energy. However there is a substantial water requirement for all forms of electricity generation in making the raw materials and constructing and maintaining the plant. Thus although wind-power has a very low water ...

  • Laser–ablative nanostructuring of surfaces

    We present an overview of laser methods for nanostructuring of surfaces that are in the focus of ongoing research activities of our Institute (LP3). The methods imply the removal of material by laser radiation to provide either spontaneous nanostructuring of laser–illuminated surface or its controlled nano–modification. Here, the desired relief or architecture is achieved through a proper ...

  • 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 ...

  • Can solar sources meet Australia's electricity and liquid fuel demand?

    It is commonly assumed that because of its relatively high solar energy incidence Australia will be able to meet its energy demand from solar sources. However, an examination of evidence on existing and probable future efficiencies and costs indicates that it will not be possible to derive sufficient electricity or liquid fuels to sustain the present high per capita rates of consumption from ...

  • Emissions through solar PV systems – a review

    Photovoltaic (PV) system has been quoted for wide range of green house gas (GHG) emissions through life cycle assessment (LCA) studies. There are a variety of solar cell materials available, which vary in conversion efficiency and emission of CO 2 . This paper is based on the LCA analysis of PV system which starts from the production of these solar cells and goes through the stages known as ...

  • No Small Task: Regulating Nanotechnology To Ensure Safety, Maximize Benefits

    Nanotechnology is about engineering at the same size as large molecules like DNA, which is two nanometers wide — a nanometer is a billionth of a meter — or even smaller. Smallness has its virtues. Nanoscale zinc oxide diffracts light better, making a better sunscreen. Similarly, ultrathin nanoscale films are improving the efficiency of cell phone screens and photovoltaics. In the future, moving ...
