Self-powered ultrasensitive nanowire photodetector driven by a hybridized microbial fuel cell.
An integrated system consisting of a carbon fiber-ZnO hybrid nanowire (NW) multicolor photodetector is driven by a microbial fuel cell (see picture; PMMA = poly(methyl methacrylate), E = electrode). The self-powered photodetector can detect at light levels of as little as nW cm(-2) intensity with a responsivity of more than 300 A W(-1).
