Researchers at Ohio State University have accidentally discovered a new solar cell material capable of absorbing all of the sun's visible light energy. The material is comprised of a hybrid of plastics, molybdenum and titanium. The team discovered it not only fluoresces (as most solar cells do), but also phosphoresces. Electrons in a phosphorescent state remain at a place where they can be "siphoned off" as electricity over 7 million times longer than those generated in a fluorescent state. This combination of materials also utilizes the entire visible spectrum of light energy, translating into a theoretical potential of almost 100% efficiency. Commercial products are still years away, but this foundational work may well pave the way for a truly renewable form of clean, global energy.
Climate change will carry a price tag of billions of dollars for a number of U.S. states, says a new series of reports from the University of Maryland's Center for Integrative Environmental Research (CIER). The researchers conclude that the costs have already begun to accrue and are likely to endure.
Combining existing data with new analysis, the eight studies project the long term economic impact of climate change on Colorado, Georgia, Kansas, Illinois, Michigan, Nevada, New Jersey and Ohio. Studies on additional states are in the works.

Scientists at the Ohio State Institute for Materials Research recently announced that they have developed a new hyper-efficient solar material that is able to capture light from every spectrum of the rainbow. Whereas most photovoltaics are limited to collecting energy from a small range of frequencies, the new material is able to absorb energy from all spectrums of visible light at once. The breakthrough development heralds a new breed of extremely efficient solar panels on the horizon.
The City Council on Wednesday became the first in Ohio with a plan to channel grants and loans to residents and businesses to replace tar and shingles with vegetation.
Supporters of the idea want to see Cincinnati become a leader in green roofs, a European-born movement that has spread to only a few U.S. cities, including Chicago, Milwaukee and Seattle.
Technology Review has an article on thin film solar vendor Xunlight's approach - making cells on flexible steel sheets - Roll-Up Solar Panels.
Xunlight, a startup in Toledo, Ohio, has developed a way to make large, flexible solar panels. It has developed a roll-to-roll manufacturing technique that forms thin-film amorphous silicon solar cells on thin sheets of stainless steel. Each solar module is about one meter wide and five and a half meters long.
As opposed to conventional silicon solar panels, which are bulky and rigid, these lightweight, flexible sheets could easily be integrated into roofs and building facades or on vehicles. Such systems could be more attractive than conventional solar panels and be incorporated more easily into irregular roof designs. They could also be rolled up and carried in a backpack, says the company's cofounder and president, Xunming Deng. "You could take it with you and charge your laptop battery," he says.
