## Description

- description: Room-temperature bulk photovoltaic effect of a ferroelectric liquid
    crystal based on diphenylterthiophene bearing dilactate side chains is provided
    in this study. In the polarized smectic phase of this compound, the improved bulk
    photovoltaic effect was observed without electron acceptors, indicating the open-circuit
    voltage of 1.1 V. A time-of-flight measurement revealed that the hole and electron
    mobilities were retained to be over 1 × 10−3 cm2V−1s−1 at room temperature. Dielectric
    relaxation spectra exhibited that the relaxation of dipolar fluctuation shifted
    from 105 Hz to 104 Hz in the polarized smectic phase, indicating suppression of
    thermal motion of the polar side chains. By doping a fullerene derivative as an
    electron acceptor, the performance of the bulk photovoltaic effect was also enhanced
    at room temperature, indicating the power conversion efficiency of 0.24 %. The
    double chiral structure of the dilactate side chain should restrict the conformation
    of the carbonyl groups in the side chains to enhance packing of the π-conjugated
    units and to stabilize the polarized structure of the smectic phase.
