The chaos continues at SunEdison, with Francisco “Pancho” Perez, the company’s chief operating officer and executive vice president, and Steve Tesoriere, an activist investor on SunEdison’s board of directors since 2012, both unexpectedly leaving the company with no explanation given.
Copenhagen Infrastructure Partners (CIP) has boosted its stake in Scotland’s 588MW Beatrice offshore wind project after buying a further 10{f24b02adee2102ff0c5f5079c50862fc8ba5fa53f8615b567037555463da2377} from utility SSE.
adminSolar generators convert solar energy into electricity using a collection of solar cells. These cells also known as photovoltaic cells and are placed in solar panels. These panels are usually…
Wind turbines deliver environmentally friendly electricity. Yet the fiber-reinforced plastics often used in very large rotor blades are almost impossible to recycle. Not so with steel blades: since these are composed of steel, their recyclability exceeds 90 percent. Plus they cost significantly less than comparable plastic blades.
Graphene, the ultra-thin, ultra-strong material made from a single layer of carbon atoms, just got a little more extreme. Physicists have been able to create the first ever superconducting graphene sample by coating it with lithium atoms.
adminStacking two solar cells one over the other has advantages: Because the energy is ‘harvested’ in two stages, and overall the sunlight can be converted to electricity more efficiently. Researchers have come up with a procedure that makes it possible to produce thin film tandem solar cells in which a thin perovskite layer is used. The processing of perovskite takes place at just 50 degrees Celsius and such a process is potentially applicable for low cost roll-to-roll production in future.
A detailed nano-mechanical study of mechanical degradation processes in silicon structures containing varying levels of lithium ions offers good news for researchers attempting to develop reliable next-generation rechargeable batteries using silicon-based electrodes.
