Will nano flakes revolutionize solar energy?
It seems like every day we hear about a new technology that may provide the next generation of clean, green power. Whether it’s algae, wind, biomass, geothermal or some improvement on an existing technology, supposed saviors are always around the corner. Into this fraught landscape, enter nano flakes — a semiconductor nanostructure that may point the way for the next generation of solar-cell energy production. Nano flakes are the work of Dr. Martin Aagesen, a researcher at the University of Copenhagen. In 2007, Aagesen claimed that he “discovered a perfect crystalline structure” that could allow the harvesting of 30 percent of solar energy directed at a surface [source: Science Daily]. Currently, solar panels, at best, are only able to convert about 15 to 20 percent of sunlight into energy [source:
