Glass solar cell concentrators eliminate need to track sun

The Massachusetts Institute of Technology, Boston, has developed a light concentration system for solar cells that does not track the sun. The method can utilize display glass and even window glass in homes, office buildings, etc, as sunlight concentrators. In addition, said a source at MIT, it makes it possible to drop the cost of the solar cell system to a tenth or less.

Solar cell concentrators concentrate the sunlight from a large area into a smaller area, making it possible to reduce solar cell cost directly by reducing cell area. Until now Fresnel lenses and similar materials have been used, but together with mechanisms to track the sun's motion, according to a Nov. 5 Tech On report.
