Scientists at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) have set a world record in solar cell efficiency with a photovoltaic device that converts 40.8% of the light that hits it into electricity. This is the highest confirmed efficiency of any photovoltaic device to date. The inverted metamorphic triple-junction solar cell was designed, fabricated and independently measured at NREL. The 40.8% efficiency was measured under concentrated light of 326 suns. One sun is about the amount of light that typically hits Earth on a sunny day. The new cell is a candidate for the space satellite market and for terrestrial concentrated photovoltaic arrays, which use lenses or mirrors to focus sunlight onto solar cells.

The redeveloped World Trade Center will be “one of the largest fuel cell installations in the world” according to the New York Power Authority (NYPA). Under the US$10.6 million agreement between NYPA and fuel cell developer and provider UTC Power, fuel cells with a total capacity of 4.8MW will provide an on-site supplement to the renewable and other clean energy that will power the rebuilt centre. The first fuel cells will be delivered to the Freedom Tower in January 2009, and will be owned and operated by the Port Authority, which also owns the building. The fuel cells for the other three towers will be owned and operated by World Trade Center Properties, LLC. “Fuel cells are one of the environmentally beneficial technologies that the Power Authority is investing in under Governor Paterson’s leadership to combat greenhouse gas emissions and diversify the state’s energy mix. To date, we’ve installed 15 fuel cells in New York City and other locations, and expect to add to this total in support of the Governor’s ambitious goals for significant increases in the state’s renewable power,” says Roger B Kelley, NYPA President and Chief Executive Officer.

Interesting story in the Boston Globe about Westwood, Mass.-based Acumentrics, a maker of solid-oxide fuel cells. The article states the the company is working with Italian heating products firm Merloni TermoSanitari to develop a commercial household version of its fuel cell, which would hit the European market by 2010 and cost around $5,200.
