Solar cells are just like leaves, capturing the sunlight and turning it into energy. It’s fitting that they can now be made partially from trees.
Georgia Institute of Technology and Purdue University researchers have developed efficient solar cells using natural substrates derived from plants such as trees. Just as importantly, by fabricating them on cellulose nanocrystal (CNC) substrates, the solar cells can be quickly recycled in water at the end of their lifecycle.
The technology is published in the journal Scientific Reports, the latest open-access journal from the Nature Publishing Group.
