Abstract
The BHJ OPDs based on <bold>H3</bold> donor molecule with amorphous morphology exhibited high external quantum efficiency of 64% at 530 nm, a low <italic>J</italic><sub>d</sub> value of 1.8 × 10<sup>−8</sup>, and a high <italic>J</italic><sub>ph</sub> value of 9.6 × 10<sup>−3</sup> A cm<sup>−2</sup> at −3 V bias.
