Since the discovery of Rochelle salt a century ago, ferroelectric materials have been investigated extensively due to their robust responses to electric, mechanical, thermal, magnetic, and optical fields. These features give rise to a series of ferroelectric‐based modern device applications such as piezoelectric transducers, memories, infrared detectors, nonlinear optical devices, etc. On the way to broaden the material systems, for example, from three to two dimensions, new phenomena of topological polarity, improper ferroelectricity, magnetoelectric effects, and domain wall nanoelectronics bear the hope for next‐generation electronic devices. In the meantime, ferroelectric research has been aggressively extended to more diverse applications such as solar cells, water splitting, and CO2 reduction. In this review, the most recent research progress on newly emerging ferroelectric states and phenomena in insulators, ionic conductors, and metals are summarized, which have been used for energy storage, energy harvesting, and electrochemical energy conversion. Along with the intricate coupling between polarization, coordination, defect, and spin state, the exploration of transient ferroelectric behavior, ionic migration, polarization switching dynamics, and topological ferroelectricity, sets up the physical foundation ferroelectric energy research. Accordingly, the progress in understanding of ferroelectric physics is expected to provide insightful guidance on the design of advanced energy materials.

“…The PCE increased from 10.40 to 16.51% when 1 wt% of PVDF was mixed with the Pb‐halide layer. [ 63 ] After positive poling, 18.60% PCE was achieved, thereby confirming that the improved device performance was correlated with the PVDF‐exerted dipole field (Table 2: Report Z).…”

Polymers or polymeric materials are used as additives for promoting the nucleation and crystallization of perovskite films to increase the crystal grain size. Due to their high molecular weight, polymers remain within perovskite‐crystal grain boundaries (GBs), where they passivate trap sites. Furthermore, some polymers function as charge‐transport materials in interfacial layers to effectively separate charge carriers and reduce charge recombination. Certain hydrophobic polymers protect perovskite films against moisture, whereas elastic polymers contribute to the mechanical resilience of perovskite films by crosslinking and self‐healing. Although polymeric additives have become essential to perovskite fabrication, a thorough review has not summarized their application to perovskite solar cells. Therefore, various strategies are comprehensively discussed for incorporating typical polymers and 1D polymeric materials into perovskite materials to improve the efficiency and stability of perovskite devices. Herein, thermoplastic, hydrophilic, and conductive polymers and elastomers are focused and related works are chronologically discussed to clearly elucidate the advances in perovskite devices.

Several valuable scientific investigations have been conducted these last few years in materials design and device engineering for perovskite solar cells (PSCs) to make them competitive compared to traditional silicon‐based photovoltaic technologies. Consequently, high power conversion efficiency beyond 25% is nowadays reported. However, their long‐term stability remains a significant challenge to overcome. Herein, the influence of fluorinated compounds on each layer of PSCs devices and their impact on the resulted device performances and stability is spotlighted. The fluorinated compounds exhibit attractive properties due to their very high electronegativity attributed to the fluorine atom, and their strong hydrophobicity. Thus, the introduction of these compounds is found to be a successful strategy to positively suppress the surface trap states, enhancing charge collection and reducing interfacial charge recombination. Besides, a better film quality and better energy level alignment is obtained, resulting in the improvement of device photovoltaic parameters such as the open‐circuit voltage (Voc), short‐circuit current (Jsc), and fill factor (FF), and then, the device's overall power conversion efficiency (PCE). Their long‐term stability is also found to further be improved.
