Open-Shell Conjugated Polymers Enable Photothermoelectric Conversion and Detection of Short-Wave Infrared Light. [PDF]

Adv Sci (Weinh)
Efficient conversion and detection of short‐wave infrared (SWIR) photons are becoming increasingly important for emerging photonic and energy technologies. Here, we report an organic photothermoelectric device based on an open‐shell conjugated polymer that enables SWIR energy conversion and photon detection via the photothermoelectric effect.
