"Researchers from the Niels Bohr Institute at the University of Copenhagen and the Ecole Polytechnique Fédérale de Lausanne, Switzerland, have discovered that nanowires increase the efficiency of solar cells. For example, a single nanowire is able to concentrate the sunlight that a solar cell is exposed to by up to a factor of 15. The researchers contend that their findings suggest that the likelihood of creating a new type of extremely efficient solar cell in the new future is very high. “Light management is of great importance in photovoltaic cells, as it determines the fraction of incident light entering the device,” write the researchers in the study’s abstract."
