Complexation-Regulated Molecular Ferroelectric Film for Photovoltaic Devices
Large-size grains play a crucial role in enhancing the properties of ferroelectric films and improving device performance. In this work, hydroiodic acid is used as an additive to promote the crystallization of a narrow-band gap molecular ferroelectric film (hexane-1,6-diammonium pentadiammonium). The complex-regulated processes resulted in a significant increase in grain size from 0.2 to 6.4 μm (32-fold enhancement), accompanied by a reduction in band gap, optimization of the energy level structure, and enhancement of ferroelectric properties. The optimized film exhibited nearly a 10-fold improvement in the performance of ferroelectric photovoltaic devices, which is further enhanced after polarization. This study introduces complex regulation strategies for optimizing molecular ferroelectrics, offering valuable insights for future research on molecular ferroelectrics.
