David L. Chandler of the Massachusetts Institute of Technology (MIT) News Office reports that an MIT research team headed by Jeffrey Grossman has found a way to make sheets that push “towards the ultimate power conversion from a material” for solar power.  His team has managed to fabricate molecule-thick photovoltaic sheets which could pack hundreds of times more power per weight than conventional solar cells. Senior author of a new paper on the team’s study in Nano Letters, Grossman found that despite the interest in two-dimensional materials such as graphene – only an atom thick – few have studied their potential for solar applications.  Grossman says, “They’re not only OK, but it’s amazing how well they do.” Stacking sheets of …

Solar Impulse Soars on Sunlight

Andre Borschberg, CEO of the Solar Impulse Project, had this to say after he landed following the seventh flight of the Airbus-sized solar craft – but the first using its solar panels for power. “It was like a first encounter with the sun. After I had turned on the solar panel I could see the energy reserves increasing although the engines were continuously consuming power. Never before in my 40 years as a pilot have I experienced anything like this.” Martin Reichlin reported on the excitement of going solar on May 28’s second flight.  “A few minutes ago we could follow by radio how André switched on the four sectors of the round about 200 square meters of solar panels …
