Researchers Create See-Through Solar Concentrator

A team of researchers at Michigan State University has developed a new type of solar concentrator that when placed over a window creates solar energy.

The device is called a transparent luminescent solar concentrator and can be used on buildings, cell phones, and any other device that has a clear surface.

And, according to Richard Lunt of MSU’s College of Engineering, the key word is “transparent.”

The solar harvesting system uses small organic molecules developed by Lunt and his team to absorb specific nonvisible wavelengths of sunlight.

The “glowing” infrared light is guided to the edge of the plastic where it is converted to electricity by thin strips of photovoltaic solar cells.

“Because the materials do not absorb or emit light in the visible spectrum, they look exceptionally transparent to the human eye,” said Richard Lunt of MSU’s College of Engineering.
