Mischaracterization of solar cell power conversion efficiencies and widespread publication of inconsistent data in scientific journals threatens to undermine progress in organic and hybrid photovoltaics research.
Twenty years ago, researchers at Bell Labs in the USA stunned the optics world by reporting a new type of semiconductor laser — the quantum cascade laser. This laser transformed mid- and far-infrared photonics.
Silicon photonics is the optical analogue of silicon microelectronics. It promises to use photons to detect, process and transmit information more efficiently than electrical signals, and yet have low manufacturing costs as a result of using conventional silicon-integrated-circuit processes.
