More Efficient Solar Cells Thanks To CNT Films That Transmit Infrared Light

A thin film of carbon nanotubes is probably the most revolutionary material developed in the past twenty years and according to the scientists they haven’t “used” the material at its full potential and there is still a long way to go. Carbon nanotubes are useful in electronic displays, solar cells, and at other devices, but you should know that CNT thin films were used with light in the visible range. “Just in case” the scientists decided to explore their properties in infrared, and their results were very surprising.

The team of researchers from the University of California, Los Angeles, tested single-walled carbon thin films in infrared and they noticed that they have the ability to transmit infrared waves. The infrared properties of the optically-transparent and electrically-conductive CNT thin films were investigated by physicists Liangbing Hu, David Hecht, and George Grüner from UCLA.

“This is the first time that the infrared properties of conductive CNT films are fully studied through measurement and calculations,” said Hu, co-author at the study.
