Bipv Showing Eu Growth

The European Building Integrated Photovoltaics (BIPV) market shows significant growth potential, a recent Frost & Sullivan report shows.

According to the research firm's analysis, the 2007 Euro BIPV market was estimated at €143 million with a total installed capacity of 25.7 MW.

The largest market is currently Germany, followed by France, Italy and Spain. These stronger markets are paving the way for expansion, Frost says, adding that countries such as Greece, Portugal and Switzerland are also moving.

Frost & Sullivan research analyst, Akhil Sivanandan, says: 'The common factor to all the best regions ... has been the level of legislative support.'

41.1% CPV EFFICIENCY

Researchers at the Fraunhofer Institute for Solar Energy Systems (ISE) have achieved a record conversion efficiency of 41.1 % using a concentrating PV system.

Sunlight is concentrated by a factor of 454 and focused onto a 5 mm2 multi-junction solar cell made out of gallium indium phosphide, gallium indium arsenide on a germanium substrate.

The researchers at Fraunhofer ISE managed to localize defects in a region of the solar cell that is not electrically active. Even at a concentration of 880 suns, an efficiency of 40.4% was measured, Fraunhofer reports.

Prof. Eicke R. Weber, Director of Fraunhofer ISE emphasizes: 'This is an especially good example of how the control of crystal defects in semiconductors can lead to a breakthrough in technology.'

Fraunhofer ISE is working together with Azur Space in Heilbronn as well as Concentrix Solar GmbH in Freiburg to make this technology competitive as soon as possible.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
