## Description

- description: "Combining inorganic thermoelectric (TE) materials with conductive
    polymers is\r\none promising strategy to develop flexible thermoelectric (FTE)
    films and devices. As most\r\ninorganic materials tried up to now in FTE composites
    are composed of scarce or toxic\r\nelements, and furthermore, n-type FTE materials
    are particularly desired, we combined the\r\nabundant and inexpensive, non-toxic
    Zn-doped chalcopyrite (Cu1-xZnxFeS2, x = 0.01, 0.02,\r\n0.03) with a flexible
    electrical network constituted by poly(3,4-ethylenedioxythiophene)\r\npolystyrene
    sulfonate (PEDOT:PSS) and graphene for n-type FTE films. The hybrid films from\r\nthe
    custom-design of binary Cu1-xZnxFeS2/PEDOT:PSS to optimum-design of ternary\r\nCu0.98Zn0.02FeS2/PEDOT:PSS/graphene
    are characterized. Compared with the binary film, a 4-\r\nfold enhancement on
    electrical conductivity was observed in the ternary film, leading to a\r\nmaximum
    power factor of ~ 23.7 μW m-1K-2. The optimum ternary film could preserve > 80%\r\nof
    the electrical conductivity after 2000 bending cycles, exhibiting an exceptional
    flexibility\r\nowing to the network constructed by PEDOT:PSS and graphene. A five-leg
    thermoelectric\r\nprototype made of optimum films, generated a voltage of 4.8
    mV with a ΔT of 13℃. Such an\r\nevolution of an inexpensive chalcopyrite-based
    hybrid film with outstanding flexibility exhibits\r\npotential for cost sensitive
    FTE applications."
