• Vertical 1D GaN nanorod arrays/2D MoS₂/PEDOT:PSS heterostructures in wafer scale have been fabricated for flexible photodetection firstly.

• Self-powered flexible photodetector at compressive strain reveals a significantly enhanced photoresponse with a responsivity of 2.47 A W⁻¹ and response times of 40/45 µs, which are superior to the state-of-the-art flexible devices.

• This work not only provides a valuable strategy for the design and construction of tunable van der Waals heterostructures, but also opens a new opportunity for flexible sensors.
