The quest for greater solar energy efficiency

December 20, 2007 The inefficiency of solar cells in converting the sun’s rays into electricity is a key contributor to the high costs of solar energy, but new research into a novel shape of semiconductor nanostructures known as "nano flakes" may revolutionize the process and help improve the viability of clean energy derived from the sun.
