Abstract By virtue of the excellent flexibility, conformability, portability, and aesthetics, wearable photodetectors have attracted worldwide research enthusiasm over past decade. However, traditional bulk covalent semiconductors are difficult to be applied due their pronounced rigidity. Profiting from self‐passivated surface, carrier mobility, strong light‐harvesting ability, low‐dimensional van der Waals materials (LDvdWMs) shown immense potential for application in optoelectronic devices. Nevertheless, preparation flexible through exfoliation/transfer or solution methods has suffered severe drawbacks spanning low production yield, contamination, uncompetitive device properties. Therefore, researchers been committed exploring alternative strategies. In response this, current review systematically summarizes latest advancements directly constructing LDvdWM on substrates, including developing low‐melting‐point targeted materials, electron‐beam‐enabled crystallization, photonic modified chemical vapor deposition, pulsed‐laser with elaboration fundamental mechanisms enabling situ deposition LDvdWMs. Finally, tricky challenges standing way this field epitomized solutions addressing them proposed. On whole, underscores distinctive pathways development photodetectors, which probably usher next‐generation technologies.
