Zusammenfassung:Thermoelectric generator composed of crystalline radical ion salts: The unipolar charge transport along the molecular stacks facilitates complementary p‐ and n‐type organic thermoelectric materials of high electrical conductivity and of 1D electronic structure. The specific power output of 5 mW cm−2 and the zT > 0.15 below 40 K demonstrate a new field of low‐temperature thermoelectric applications unlocked by organic metals.
