Special Issue Information

Dear Colleagues,

The evolution of information technology has driven the development of sensors into a new era, featuring the advancement of Internet of Things (IoT), Industry 4.0, big data, artificial intelligence (AI), robotics, and digital health, requiring sensors to become more connected and intelligent. The vision of “everything being connected” requires sensors to perform new and diverse tasks, which are difficult to meet with conventional devices. Advanced optoelectronic sensory devices that provide non-invasive, rapid, precise perceptions of optical information by converting to measurable electrical signals, are becoming critical IoT tools. Moreover, the recent progress in multimodal, biomimetic, AI-enhanced, all-in-one optoelectronic sensing materials and devices are advancing the frontiers in smart electronics, aiming at, ultimately, low-power consumption and superior functionality.

In light of the importance of next-generation optoelectronic sensory materials and devices and their rapid advances, we would like to organize this Special Issue on Electronics. Both review papers and research articles are welcome.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  1. 2D material-based optoelectronic devices;
  2. Quantum dot-based optoelectronics;
  3. Perovskite-based optoelectronic devices;
  4. Organic optoelectronics;
  5. Inorganic thin-film optoelectronics;
  6. Photodetectors and photovoltaics;
  7. Optoelectronic sensory hardware and systems;
  8. Computational optoelectronics and machine vision;
  9. Neuromorphic optoelectronic devices and reconfigurable systems.

In bulk heterojunction (BHJ) organic solar cells (OSCs) employing perylene diimide (PDI)-based non-fullerene acceptors, excessive intermolecular interactions among PDI units lead to severe aggregation and pronounced donor–acceptor phase separation, both of which critically limit device performance. To address these issues, numerous structurally engineered PDI derivatives have been developed. In particular, twisted multi-PDI architectures designed to suppress intermolecular aggregation have shown improved morphological control; however, such twisted structures are often highly amorphous, which reduces electron-transport efficiency and constrains OSC performance. In this work, we introduce a mixed-acceptor strategy combining a twisted PDI dimer (SF-PDI2) with a planar monomeric PDI (m-PDI) to balance aggregation and morphological uniformity. Ternary blend OSCs consisting of PTB7-Th as the donor and these two PDI acceptors exhibit systematic performance variations depending on their relative ratios. At the optimized composition (SF-PDI2:m-PDI = 90:10 by weight), the device outperforms single-acceptor systems, which is attributed to controlled aggregation arising from the complementary structural features of the two PDI acceptors. This study demonstrates that combining mixed PDI acceptors with similar molecular moieties enables precise control of aggregation, improving both morphology and photovoltaic performance. Full article
