Abstract
Jones for OPDs. Photomultiplication mechanisms and spectral engineering enable ultrahigh responsivity (EQE >770 000%) and narrowband detection. Application-oriented designs, including intrinsically stretchable all-polymer systems and semi-transparent architectures, highlight P3ATs' versatility in wearable electronics and building-integrated photovoltaics. Future directions emphasize truly green solvents, simplified acceptors, and machine learning-guided material design to advance commercialization. By synergizing material innovation with scalable processing, P3ATs and their close variants offer a sustainable pathway for next-generation optoelectronics, balancing performance, stability, and environmental impact.
