This is an old report, but still very very and VERY relevant dream … Back in 2014 A team of researchers at Michigan State University developed a new type of solar concentrator that when placed over (an existing!!!) window creates solar energy while doesn’t block the view, well isn’t that a WoW?
It is called a transparent luminescent solar concentrator and all of us could dream of all possible application areas, right? The interesting part of the outcome of this research was that unlike the past efforts, that the energy production was inefficient and the materials were highly colored, this time it is transparent & with acceptable efficiency. The solar harvesting system uses small organic molecules developed by Lunt and his team to absorb specific non-visible wavelengths of sunlight. “We can tune these materials to pick up just the ultraviolet and the near infrared wavelengths that then ‘glow’ at another wavelength in the infrared,” said Richard Lunt.
Back in 2014, the conversion efficiency was close to 1 percent, but noted they aim to reach efficiencies beyond 5 percent when fully optimized. This was when best colored LSC has an efficiency of around 7 percent !!! This research was featured on the cover of of the journal Advanced Optical Materials at 2014. Other members of the research team include Yimu Zhao, Benjamin Levine and Garrett Meek. ——————–***——————–
