Summary

Story summary

Researchers at Rice University found that structural imperfections in the organic semiconductor 9,10-bis(phenylethynyl)anthracene (BPEA) enhance performance by creating energy-flow pathways through triplet-triplet annihilation.
This challenges the view of defects as flaws and suggests they can be strategically used in materials engineering.
The study was published in the Journal of the American Chemical Society, and the findings have implications for solar energy, optoelectronics, and sensing technologies.
