A photodetector includes an active layer formed of an inorganic/organic hybrid perovskite material, such as organometal halide perovskites. The perovskite hybrid photodetector provides low dark-current densities and high external-quantum efficiencies, resulting in a photodetector with enhanced photoresponsivity and detectivity. Advantageously, the perovskite hybrid photodetector may be prepared by solution processing, and is compatible with large-scale manufacturing techniques.
