Researchers at the US Department of Energy's Lawrence Berkeley National Laboratory have demonstrated a way to fabricate efficient 3D solar cells from low-cost and flexible materials.
Construction is underway of PlanetSolar, the first ship that is planned to circumnavigate the globe using solar power alone. The 30-metre ship will carry a permanent crew of two but can accommodate up to 50 for shorter trips.
Unconventional solar cell materials that are as abundant but much less costly than silicon and other semiconductors in use today could substantially reduce the cost of solar photovoltaics, according to a new study from the Energy and Resources Group and the Department of Chemistry at the University of California, Berkeley, and the Lawrence Berkeley National Laboratory (LBNL). These materials, some of which like iron pyrite are highly abundant, could expand the potential for solar cells to become a globally significant source of low-carbon energy, the study authors said.
Some of the tiniest solar cells ever built have been successfully tested as a power source for even tinier microscopic machines, according to an article in the inaugural issue of the Journal of Renewable and Sustainable Energy (JRSE), published by the American Institute of Physics (AIP)
Ohio State University chemists have created a new material that overcomes two of the major obstacles to solar power moving mainstream
