  • With 8.1% efficiency and 43.3% transparency, new carbon-based solar cells are a big step towards making skyscrapers generate power.
  • The new cells were made with a new material, designed to be transparent for visible light, and absorb near-infrared light which carries most of sunlight’s energy.
  • Previous transparent cells used 2-3% of light that hit them, these new cells can use up to 5% - study authors are aiming for 7% in the next iteration.
  • They’re also studying if it makes economic sense to install transparent solar cell windows in new and existing buildings.
