| Abstract: We design a photo-thermoelectric nanogenerator (PTENG) based on a flexible film of molybdenum disulfide (MoS2) dispersed in a pyroelectric polymer. The transition-metal dichalcogenide as thin-layered nanosheets can harvest the incident near-infrared (NIR) light and convert it into thermal energy. The pyroelectric polymer subsequently transduced the thermal energy collected by the inorganic nanosheets into electric energy. Under NIR irradiation, the PTENG can generate voltage and photocurrent instantly, and the output kept at high level for a long time. High thermoelectric conversion coefficient was obtained, which arised from efficient coupling between photothermal and pyroelectric effects. Theoretical simulation distinguished the contribution of MoS2 in the polymer nanocomposite. MoS2 significantly increased the temperature change rate in pyroelectric polymer films, leading to enhanced photoelectric response in the device. |
