A biomimetic antenna for gathering sunlight may one day transform solar-powered devices. Sometimes when people talk about solar energy, they tacitly assume that we´re stuck with some version of the silicon solar cell and its technical and cost limitations. Not so. The invention of the solar cell, in 1941, was inspired by a newfound understanding of semiconductors, materials that can use light energy to create mobile electrons–and ultimately an electrical current....

Structure of artificial light harvesting antenna determinedAn international team of researchers has modified chlorophyll from an alga so that it resembles the extremely efficient light antennae of bacteria. The team was then able to determine the structure of these light antennae. This is the first step to converting sunlight into energy using an artificial leaf. The researchers will be publishing an article on their research findings in the online Early Edition of the PNAS journal in the...

An international team of scientists has determined the structure of the chlorophyll molecules in green bacteria that are responsible for harvesting light energy. The team's results one day could be used to build artificial photosynthetic systems, such as those that convert solar energy to electrical energy. A research paper about the discovery was published on May 4, 2009 in the Proceedings of the National Academy of Sciences. The scientists found that the chlorophylls are highly efficient at...

A U.S.-led international team of scientists says it has determined the structure of chlorophyll molecules in green bacteria that harvest light energy. The researchers said their findings might one day be used to build artificial photosynthetic systems, such as those that convert solar energy to electrical energy. We found that the orientation of the chlorophyll molecules make green bacteria extremely efficient at harvesting light, said Pennsylvania State University Professor Donald Bryant,...

'Taco shell' proteinResearchers at Washington University in St. Louis have figured out the orientation of a protein in the antenna complex to its neighboring membrane in a photosynthetic bacterium, a key find in the process of energy transfer in photosynthesis.Robert Blankenship, Ph.D., Markey Distinguished Professor of biology and chemistry in Arts & Sciences, led a team that for the first time combined chemical labeling with mass spectroscopy to verify the orientation. The team also...

WASHINGTON -- The wonderland known as Yellowstone National Park has yielded a new marvel - an unusual bacterium that converts light to energy. The discovery was made in a hot spring at the park where colorful mats of microbes drift in the warmth. "This thing was just bizarre," David M. Ward, a professor of microbial studies at Montana State University, said of the bacterium. Plants use photosynthesis to turn light into energy, of course, and so do some other bacteria. But, Ward said, the...
