This letter reports a PCDTBT: PCBM: CdSe tetrapod shaped nanocrystals (NCs) nanocomposites based hybrid inorganic-organic ultraviolet (UV)-Visible (Vis) photodetector fabricated on fluorine-doped tin oxide (FTO) coated glass substrate. The tetrapod shaped nanocrystals synthesized by solution method are mixed with PCDTBT: PCBM to achieve the desired nanocomposites for the active layer of the device. The ZnO nanorods are used as the electron transport layer (ETL) and a MoO _x layer is used for the hole transport layer (HTL) in the proposed device. Under a reverse bias of −2 V, the proposed device showed a responsivity of 1830 mAW ⁻¹ (344 mAW ⁻¹ ), detectivity of $1.75\times 10^{12}$ ( $3.3\times 10^{11}$ ) Jones, a rise time of 5.73s (0.02 s) and fall time of 6.41s (0.14 s) at 375 nm (540 nm) UV (Visible) light of $13.1~\mu $ Wcm ⁻² ( $41.2~\mu $ Wcm ⁻² ) low light intensity.
