Moving light to make electricity
The Massachusetts Institute of Technology has emerged as a hotbed for research and technology development in energy. Among the many companies already spun out of MIT is Covalent Solar.
Company technicians have used a relatively common dye to coax light to move to the edges of glass sheets where they plan to put solar cells. The light is concentrated to make more electricity from cells. The design also uses less silicon cell material than traditional panels.
