Ultrahigh and Broad Spectral Photodetectivity of an Organic-Inorganic Hybrid Phototransistor for Flexible Electronics

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 1012 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.
