The creation of new organic–inorganic phototransistors with high and broad spectral photosensitivity is reported. The extended charge transport and photoconductivity between the layers in the bilayer structure results in a notable detectivity of over 10 12 Jones and a linear dynamic range of over 100 dB at a broad spectral bandwidth across the UV–NIR range. Furthermore, the considerably reduced persistent photocurrent effect of In–Ga–Zn–O (IGZO)‐based hybrid phototransistors is first demonstrated via an organic–inorganic bilayer approach.
