Smallest Ever Solar Cells
Scientists from University of Tokyo, Japan, and Johannes Kepler University, Austria, have done another marvelous job in the field of physical sciences. They have developed lightweight and ultrathin solar cells, which are smallest ever solar cells developed. These tiny solar cells are comprised of electrodes on a plastic foil with a thickness of 1.9 micrometers i.e. the size thinner than a thread of spider silk.
These solar cells are not only thinner than any other solar cell but also they are highly flexible that they can be easily wrapped around a single human hair. They can also resist many of the extreme mechanical situations such as deformations.
Researchers have written,
“These ultrathin organic solar cells are over ten times thinner, lighter and more flexible than any other solar cell of any technology to date.”
Researchers are optimistic that these cells can be made better to get more electricity from sunlight. This tiny device would be available within next five years.
This research has been published in Nature Communications.
Recently, Google has announced about its “Project Glass” (Eyeglasses) and one of the issues on which Google’s researchers are working is what would be the better option to charge these glasses. I think these ultrathin solar cells could help them. Another better option for both of the researchers is to get focal point of the eyeglasses and to place the solar cells as much close to that focal point as possible so that they could get maximum output from the solar cells.
