MrSeb writes "Oh graphene! The cheap, easy-to-manufacture one-atom-thick sheet of carbon can add yet another weird, fantastical, and possibly life-changing ability to its list of characteristics: it has an incredibly sensitive thermoelectric response to light. In layman’s terms: graphene, when struck by light of almost any wavelength, can produce an electric current. Discovered by MIT and Japanese researchers, this effect (hot carrier response) works at room temperature, with a wide range of light spectra, and at low intensities, which means it could replace photovoltaic solar panels, photodetectors in astronomy and photography, and even some medical applications (searching for disease and toxin)."
