MIT researchers suggest graphene could be used to build a better camera sensor

As you may have noticed from the pace of research over the past few years, graphene is promising to make a whole lot of things a whole lot better. Now, it seems, you can also add camera sensors to the list. A team of MIT researchers recently discovered that graphene can serve as a photodetector over a "very wide energy range," and that it works particularly well in infrared light, where other types of detectors often come up short. That, the researchers say, could open to the door to everything from better nightvision systems to more advanced detectors for astronomical telescopes -- not to mention more inexpensive camera sensors in general, since graphene is cheap to work with. What's more, the researchers also suggest that those same light-detecting abilities could make graphene a good material for collecting solar energy, although they note that there's still much more research needed to determine if it's truly an efficient means of generating energy.
