Sun Windows Technologies (ISIN: CN8435902335), a pioneer in the development of photovoltaic energy, specializing in development, financing and administration, construction, operation, maintenance and consulting, today announced that its team of researchers has developed a new type of solar concentrator that, when placed over a window, creates solar energy, while allowing people to actually see through the window. And, according to Chen William Black, Head of Research and Development, the key word is “transparent.”
Research in the production of energy from solar cells placed around luminescent plastic-like materials is not new. However, these past efforts have yielded poor results – the energy production was inefficient and the materials were highly colored.
“No one wants to sit behind colored glass,” said Black, an assistant professor of chemical engineering and materials science. “It makes for a very colorful environment, like working in a disco. We take an approach where we actually make the luminescent active layer transparent itself.”
The solar harvesting system uses small organic molecules developed by Black and his team, to absorb specific non-visible wavelengths of the sunlight.
“We can tune these materials to pick up just the ultraviolet and the near-infrared wavelengths, which then ‘glow’ at another wavelength in the infrared,” he said.
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,” Black said.
One of the benefits of this new development is its flexibility. While the technology is at an early stage, it has the potential to be scaled for commercial or industrial applications at an affordable cost.
