Imagine a world where beautiful multi-colored window surfaces capture energy.
University of Michigan Engineers are developing these new new colored, transparent solar cells.
They can be installed anywhere glass is currently being used. They are not as efficient as black, but they don't need to be.
Imagine big glass buildings in metropolises generating more electricity than they use, simply by being covered with these?
The cells, believed to be the first semi-transparent, colored photovoltaics, have the potential to vastly broaden the use of the energy source, says Jay Guo, a professor of electrical engineering and computer science, mechanical engineering, macromolecular science and engineering who devised them.
Their color isn't derived from dyes, but rather from adjusting the thickness of their semiconductor layer to reflect certain wavelengths of light.
