Perovskite Photovoltaics: Hitting Their Stride
Researchers are finding new uses for an old material in photovoltaics. But can they engineer perovskite into a solar cell that’s better than the current state-of-the-art?
by Lynn SavageNegawatts: Optics, Photonics and Energy Savings
Five scientists survey the potential energy savings that could flow from selected optical technologies, ranging from optical data interconnects to photonic gas sensors.
by Edited by Keith GoossenExoplanets: Getting a Closer Look
Sophisticated new techniques are directly imaging giant planets outside of our solar system and recording spectra that reveal the composition of their atmospheres. And telescopes capable of directly imaging Earth-sized exoplanets are on the technological horizon.
by Jeff HechtPlasmonics: The Rise of Quantum Effects
The emerging discipline of quantum plasmonics, which promises new applications and approaches in quantum information systems, formed the topic of a recent OSA Incubator Meeting.
