• 2D materials, such as graphene, transition metal dichalcogenides, and black phosphorus, have become the most potential semiconductor materials in the field of optoelectronic devices due to their extraordinary properties. Owing to the layer‐dependent and appropriately sized bandgaps, photodetectors based on various 2D materials are designed and manufactured rationally. Utilizing the unique properties of 2D materials, many surprising physical phenomena of junctions based on 2D materials can be obtained after different 2D materials are stacked together. This makes heterojunctions more popular than 2D materials themselves, and the design of 2D materials for human beings is easier than ever. In this review, recent progress in optoelectronic applications based on 2D materials and their heterojunctions is summarized and discussed. Owing to their controllable optoelectronic properties, good mechanical flexibility, strong light–material interaction, and broadband optical response, 2D materials and their heterostructures are attracting increasing attention for photonic applications. The basic properties, syntheses, and working mechanisms of 2D materials used in optoelectronic devices are introduced, and the challenges to achieving practical applications of 2D materials are also discussed.
