  • Flexible and transparent reduced graphene oxide and silk fibroin composite films with kilo–ohm square resistance

    A general method of producing flexible transparent conducting thin film composed of reduced graphene oxide (RGO) and silk fibroin (SF) is demonstrated; the production is accomplished via spin–coating followed by the process of chemical reduction and transferring. Adjusting the amount of spin–coating performed produces RGO/SF–based (GSF–based) composite films with resistances ranging from 22 kΩ/sq ...

  • 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 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 ...

  • Net-zero energy: a case study on renewable energy and policy issues at Richardsville Elementary School, Kentucky

    Blazing the trail as the first net-zero energy school, Richardsville Elementary School, Kentucky produces as much renewable energy as it consumes. The high performance, LEED® Gold certified facility was opened in October 2010 for 550 students. Key elements included insulated concrete form-walls, geothermal HVAC systems with decentralised and distributive pumps, active day-lighting with light ...

  • 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 ...

  • Spi-Sun simulator sets the standard

    Solar Simulators are critical to the industry testing photovoltaic modules featuring light sources that closely match the solar spectrum. Spire’s simulators can test the full range of solar modules – including crystalline or thin film. The importance of solar simulation is clear – solar modules must be tested under a standard set of conditions to assure consistency of results. ...

  • New Antenna, merged with solar panels

    The EPFL researchers have managed to merge antennas and solar cells in a mixed device that promises unprecedented efficiency. It is a first step towards the development of more compact and lighter satellites, but also to the improvement of mobile communication systems used in case of disaster. Traditionally, telecommunication antennas and solar cells do not mix. They must function independently ...
