Solar Waveguide Windows Generate Energy From Inside and Out

Rice University engineers have suggested a colorful solution to next-generation energy collection: Luminescent solar concentrators (LSCs) in your windows.Led by Rafael Verduzco and postdoctoral researcher and lead author Yilin Li of Rice’s Brown School of Engineering, the team designed and built foot-square “windows” that sandwich a conjugated polymer between two clear acrylic panels.That thin middle layer is the secret sauce. It’s designed to absorb light in a specific wavelength and guide it to panel edges lined with solar cells. Conjugated polymers are chemical compounds that can be tuned with specific chemical or physical properties for a variety of applications, like conductive films or sensors for biomedical devices.
