Clear Solar Cells Power Up Windows
The vast real estate of windows in office buildings and skyscrapers could be a fruitful field for harvesting solar energy—if lightweight solar cells could be made with high enough efficiency and aesthetic appeal. Now researchers at Oxford University report semitransparent solar cells that might do the trick (ACS Nano 2013, DOI: 10.1021/nn4052309).
For use in windows, solar cells need to absorb enough light to produce sufficient energy . . .
