Thin film photodiode based on narrow-bandgap polymer PPCPD achieved high detectivity and quantum efficiency and realized high pixel-density image arrays without pixel-level-patterning. Short-wavelength infrared imaging could be scanned and read out by a 1 × 256 linear array with 25 μm × 25 μm pixel pitch.
Abstract
Combining the strategies of introducing larger heteroatom, regio-regular backbone and extended branching position of side-chain, we developed polymer semiconductors (,PPCPD,) with narrow band-gap to construct the photosensing layer of thin-film photodiodes and image arrays. The spectral response of the resulting organic photodiodes spans from the near ultra-violet to short-wavelength infrared region. The performance of these short-wavelength infrared photodiodes in 900–1200 nm range achieved a level competitive with that of indium gallium arsenide-based inorganic crystalline detectors, exhibiting a specific detectivity of 5.55×10,12, Jones at 1.15 μm. High photodetectivity and quantum efficiency in photodiode with amorphous/nanocrystalline thin-films of 100−200 nm thickness enabled high pixel-density image arrays without pixel-level-patterning in the sensing layer. 1 × 256 linear diode arrays with 25 μm × 25 μm pixel pitch were achieved, enabling high pixel-density short-wavelength infrared imaging at room temperature.
