Nanoflakes could make solar cells more efficient
(Nanowerk News) A new material, nano flakes, may help drive the solar energy industry into the future. Dr. Martin Aagesen, a researcher at the University of Copenhagen and director of SunFlake Inc. is currently developing the technology which takes advantage of crystalline structures to absorb more sunlight than traditional solar photovoltaic (PV) cells.
Dr. Aagesen believes that the nano flakes have the potential to convert up to 30 percent of solar energy into electricity because the nano flakes also reduce the distance energy has to travel in the c ell. These cells would also use smaller amounts of semiconducting silicium making them less expensive than the PV cells currently available.
"I discovered a perfect crystalline structure. That is a very rare sight. While being a perfect crystalline structure we could see that it also absorbed all light. It could become the perfect solar cell," said Dr. Aagesen.
