  • Further achievements in the realm of organic and molecular electronics — even at the level of device applications — requires greater understanding of the materials at a fundamental level. This insight can only come with input from researchers in several disciplines working together on the materials from different perspectives.

  • Simplification in large-area manufacturing of complex organic electronics is a critical step towards ubiquitous, flexible, portable applications; why not make the molecules do the work?

  • Charge generation and transport are crucial to the performance of organic solar cells, but the mechanism remains controversial. Causa’ et al. show that the phase morphology of polymer:fullerene blends determines the exciton dissociation at femtoseconds, although the spatial separation can occur at picoseconds.

  • Photocarrier generation at organic semiconductor heterojunctions is a crucial process, yet its mechanism and dynamics remain unclear. Here, Provencher et al.show little change in polymer structure following the charge-transfer process and interpret the observation in terms of unbounded electron-hole pairs.

  • Though solution-processed conjugated polymers with inverted temperature activated transport have been reported, the origin of this behaviour is unclear. Here, the authors realize temperature-independent electron transport above 280 K in a donor-acceptor copolymer through microstructural engineering.

  • The field of organic electronics has acknowledged that the key to process and device optimization is to elucidate the correlation between the active layer morphology and performance. This Review outlines how this can be achieved using accessible approaches from materials science and classical polymer thermodynamics.

  • The recent demonstration that highly disordered polymer films can transport charges as effectively as polycrystalline semiconductors has called into question the relationship between structural order and mobility in organic materials. It is now shown that, in high-molecular-weight polymers, efficient charge transport is allowed due to a network of interconnected aggregates that are characterized by short-range order.

  • Difficulties in controlling the nucleation and growth of thin films of organic semiconductors have impaired progress in organic electronics. Now, efficient control of the crystallite nucleation and microstructure of a broad range of organic semiconductors without detriment to their electronic properties has been achieved through the addition of small quantities of additives—a widely used strategy in bulk polymer crystallization.
