• Halide perovskites have established their intriguing performances in optoelectronics and been expanded to energy harvesting application when incorporated into polymers due to their polarization related properties. Yet, fundamental understanding of the electrical conduction behavior of such composites has seldomly been addressed. Herein, composite films employing CH3NH3PbBr3 (MAPB) nanoparticles and ferroelectric polymer poly(vinylidenefluoride-co-trifluoroethylene) [P(VDF-TrFE)] have been investigated upon their conduction behaviors. Both electric field and temperature-dependent currents have been thoroughly analyzed based on hopping and space charge-limited current mechanisms in combination with trap energy and trap density calculation from thermal stimulated depolarization currents. The conduction mechanism of MAPB/P(VDF-TrFE) composite has been established within the frame of band diagram. Our studies, thus, are essential for developing high-performance optoelectronics and energy harvesters based on halide perovskites/polymer composites.
