Tibet’s largest solar power plant to become operational in May
The largest solar power plant in Southwest China’s Tibet Autonomous Region will become operational in May to help ease the plateau region’s power shortages.
The 30-megawatt solar photovoltaic generation project in Xigaze Prefecture, about 3 km northwest of Tibet’s second largest city Xigaze, is perched at 3,895 meters above sea level, the project’s steering committee said Thursday in a press release.
It said the project would cost 800 million yuan (122 million U.S. dollars), funded solely by Linuo Power Group, a leading provider of solar photovoltaic power generation systems based in east China’s Shandong Province.
Construction of the first phase, costing 249 million yuan and covering an area of 30 hectares, began in May last year. It will generate up to 20.23 million kilowatt-hours of electricity annually, the document said.
German bored piling technology was used to dig through the thick layer of perennial frozen earth on the plateau, said project manager Zhang Daobin. It was the first time such technology had been employed in Tibet.
He said the first phase of the project alone could ease some power shortages in Xigaze Prefecture, by supplying electricity for more than 100,000 farming and herding families.
The clean energy project would help save 7,600 tonnes of coal annually and reduce carbon dioxide emissions by at least 13,800 tonnes, said Zhang.
Last year, a 10-megawatt solar photovoltaic generation project was built in Yangbajing, a town 90 km northwest of Tibet’s capital Lhasa, with a designed power generation capacity of 430 million kwh during its 25-year life span.

Thin film solar technology promises charging phones without need of wires
Electronics users may soon never have to plug their cellphone or e-book reader into a wall again thanks to the latest innovations in thin film solar technology. French company Wysips is planning to launch a transparent solar film that will fit over a device’s screen, charging it without the need for wires.
Scientific breakthrough that will increase the conversion efficiency of solar photons into electricity
Researchers from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) and the University of Colorado, Boulder (UCB), have reported the first designed molecular system that produces two triplet states from an excited singlet state of a molecule, with essentially perfect efficiency. The breakthrough could lead to a 35 percent increase in light-harvesting yield in cells for photovoltaics and solar fuels. The experiments, using a process called singlet fission, demonstrated a 200 percent quantum yield for the creation of two triplets of the molecule 1,3-diphenylisobenzofuran (DPIBF) at low temperatures. In singlet fission, a light-absorbing molecular chromophore shares its energy with a nearby non-excited neighreackthroghboring molecule to yield a triplet excited state of each. If the two triplets behave independently, two electron-hole pairs can be generated for each photon absorbed in a solar cell. This process could subsequently increase by one third the conversion efficiency of solar photons into electricity or solar fuels.Sam Wilkinson from IMS Research, about the future of PV market

U.S. Energy Secretary Steven Chu congratulated a team of researchers at the Department’s BioEnergy Science Center who have achieved yet another advance in the drive toward next generation biofuels: using bacteria to convert plant matter directly into isobutanol, which can be burned in regular car engines with a heat value higher than ethanol and similar to gasoline. This research is part of a broad portfolio of work the Department is doing to reduce America’s dependence on foreign oil and create new economic opportunities for rural America.DIN-Y: Solar-powered mobile conference unit

UK needs to recycle its stockpile of waste plutonium into fuel
Former chief scientific adviser to the government Sir David King has today urged the government to recycle its giant stockpile of waste plutonium into fuel for new-build nuclear reactors, as part of a major new report calling for an overhaul of the UK’s nuclear energy sector.
