Nanowires to Boost Solar Energy Efficiency
A team of Danish nanophysicists has developed a new method for manufacturing nanowires and believes the discovery will have great potential for the development of nanoelectronics and highly efficient solar cells.PhD student Peter Krogstrup, from the Nano-Science Center at the Niels Bohr Institute, University of Copenhagen, developed the method during his dissertation.
Different materials capture energy from the sun in different and quite specific absorption areas.They have produced nanowires that contain two different semiconductors – GaInAs and InAs,which each have their own absorption area, they can collectively capture energy from a much wider area. We can therefore use more solar energy if we produce nanowires from the two superconductors and use them for solar cells.
