Photoresponse performance of the conformal PTCDI-C13H27 phototransistor array on different curved objects. (a1,a2,b1,b2) Typical photograph and schematic images (inset), typical transfer characteristics under illumination, Ilight, Idark and Ilight/Idark of the device at strain bending parallel and vertical to channel length, respectively. The bending radius is from 3.3 to 0.23 cm. (c1) Optical microscopy image of the compound eyes from a real dragonfly eye. The right-bottom optical microscopy image in the inset shows a real device array adhered on a hemisphere lens with the bending radius of 0.64 cm. (c2) Photosensitivity mapping with a 3 × 3 OPT array as shown in the inset of Figure c1. The wavelength of illumination is 489 nm and light power density is 100 μW cm−2.
