Carbon nanotubes are becoming increasingly attractive for photovoltaic solar cells as a replacement to silicon. Researchers at Umeå University in Sweden have discovered that controlled placement of the carbon nanotubes into nano-structures produces a huge boost in electronic performance. Their groundbreaking results are published in the prestigious journal Advanced Materials.
Carbon nanotubes, CNTs, are one dimensional nanoscale cylinders made of carbon atoms that possess very unique properties. For example, they have very high tensile strength and exceptional electron mobility, which make them very attractive for the next generation of organic and carbon-based electronic devices.
