Scientists in Canada have dramatically raised the practical potential of spray-on solar by developing a more efficient method for attaching microscopic light-sensitive materials to flexible surfaces.

The new approach was developed by Ilan Kramer, a post-doctoral fellow from the Edwards S. Rogers Sr. Department of Electrical & Computer Engineering at the University of Toronto. It involves spraying the light-sensitive materials onto complex surfaces using a device cobbled together from cheap and commonplace mechanical parts. “My dream…
