Land use in Africa has major impact on carbon emissions, study

Land use in the continent of Africa could determine the intensity of the impact of carbon emissions, according to a study done by the University of Edinburgh. On a pioneering study on the African savannas, researchers at the University of Edinburgh found that south-central Africa is suffering from deforestation that is driven by increased population, and increased demand for trees for agriculture and fuel. The...

A touch of purple for better hydrogen production

The visibly purplish tinge of the salt flats of California and Nevada are caused by microorganisms known as archaea. These microorganisms contain a protein called bacteriorhodopsin which scientists at the United States Department of Energy’s Argonne National Laboratory have used to develop an efficient photocatalyst for hydrogen production. Bacteriorhodopsin have the ability to act as proton pumps, they capture...

Thinner than paper light-absorption materials developed at Stanford

A wafer of material thousands of times thinner than paper could lower the cost and improve the efficiency of solar cells. Researchers from Stanford University have built an efficient absorber of visible light out of nanosized materials. When trying to cut the costs of solar, most scientists look to either enhance the efficiency of the materials used or to use less expensive materials. The Stanford team managed to do both...

Nanomaterial developed to help Australia reduce CO2 emissions

Researchers from the University of Adelaide have developed a new nanomaterial that can reduce carbon dioxide emissions from coal-fired power stations. The nanomaterial, called a “metal-organic framework,” can separate the greenhouse gas carbon dioxide from nitrogen in the waste gas released by coal power generation that is a major contributor to climate change. “It’s like a sponge but at a nanoscale. The material has...

Colored solar cells developed for better building design

German researchers have developed a way to make colored solar cells from paper-thin silicon wafers. While color doesn’t really matter when we’re talking about solar panels efficiency, it does matter a little when designers or property owners are thinking about how a solar panel might contribute to the over-all aesthetics of a building or facility. “Not enough work has been done so far on combining...

Electrocatalyst for better batteries, fuel cells developed in Korea

A new electrocatalyst for oxygen reduction has been developed at the Ulsan National Institute of Science and Technology in South Korea. Led by Prof. Jaephil Cho, dean of the Interdisciplinary School of Green Energy at U.N.I.S.T., the research team developed a new strategy to design inexpensive and durable electrochemical oxygen reduction catalysts for both metal-air batteries and fuel cells. Electrocatal...

Antifreeze used in manufacture of cheaper thin-film solar cells

A little antifreeze is a key component to a relatively cheap semiconductor material that researchers at Ohio State University are studying for use in future solar technologies. “The global use of solar energy may be held back if the materials we use to produce solar cells are too expensive or require the use of toxic chemicals in production,” said Greg Herman, an associate professor of Chemical, Biological and...

Atom thick sheets of material for thinner and lighter solar cells

Using materials that are only one-molecule thick, researchers at the Massachusetts Institute of Technology are looking to produce the thinnest and most lightweight solar panels possible. By stacking two layers of what are called two-dimensional materials such as graphene and molybdenum disulfide, Jeffrey Grossman and his team have created a solar cell that is only 1 nanometer thick. Mr. Grossman, who is the Carl...

Manmade wetlands storing huge amounts of carbon

Manmade wetlands hold great potential as long-term carbon sinks. According to researchers at the Florida Gulf Coast University, manmade wetlands do not only help halt the spread of agricultural pollutants, they also pull and hold carbon dioxide from the air. The director of the Everglades Wetlands Research Park at the university, Bill Mitsch, along with co-author of the report Blanca Bernel, found that two manmade...

Faster and more accurate method of inspecting P.V. systems developed

Scientists at the University of Stuttgart, Institute of Photovoltaic in Germany, have developed a method of inspecting photovoltaic systems that have novel advantages over current inspection methods. The P.V. module-assessment innovation, which was developed by Stuttgart Solar Centre, a working group from the Institute of Photovoltaic at the University of Stuttgart and the Steinbeis Centre for Photovoltaic, is called...
