Artificial Photosynthesis Could Power Future Jet Airplanes

To fly a jet by solar power might take football-fields worth of solar cells; but to turn sunlight into liquid fuel via artificial photosynthesis could someday power jet airplanes. Postdoctoral scholar Shane Ardo uses light to produce hydrogen gas (the bubbles) in water at the California Institute of Technology. There, at the Joint Center for […]

Quantum Dots Could Boost Solar Efficiency by 100%

Researchers at the University of Texas at Austin are hot on the heels of a discovery that could more than double the efficiency of solar cells. The trick is to use tiny nanoscale crystals called quantum dots to capture more of the available energy in sunlight, including energy at the high end of the scale.¬† […]
