Graphene is considered to be a promising candidate for next-generation optoelectronic devices due to its unique electrical and optical properties, such as high transparency and broadband absorbance in the visible to near-infrared spectral regime. Therefore, there have been attracted much attention on the studies of the photoresponse of grapheme-matal interface and development of graphene-based photodetecors. However, these devices are usually fabricated by expensive lithography or e-beam processes. In the work, a practical method to fabricate graphene photodtectors by ease and low-cost solution process is reported which offer an opportunities for large-area devices.
