“…This behavior can be ascribed to the self‐polarization usually found in ferroelectric thin films due to strain gradients generated in the perovskite cell by substrate clamping, which induces a preferred orientation of ferroelectric dipoles and hence a net polarization in the system. [ 31 ] Both short‐circuit current density and open‐circuit voltage considerably increase with poling, reaching maximum values of 90 µA cm −2 and 0.13 V. These data suggest the strong remanence of the ferroelectric dipoles obtained after polarization even at low voltages during the course of the photovoltaic measurement. From the former results, a power output of 11.7 µW cm −2 is calculated (extrapolated to a value of ≈20 µW cm −2 at 1 Sun) which is one order of magnitude higher than that corresponding to the non‐polarized sample.…”

The direct integration of crystalline oxide layers into flexible electronic systems requires the development of relatively simple, low-temperature processing routes. Seeding represents a powerful strategy to reach this objective by the generation of preferential sites for the nucleation of crystalline phases with a reduced energy barrier. Here, a novel approach is reported where nanoseeds are generated in situ from a precursor solution using a solvent-engineering strategy (solvent-antisolvent). The controlled addition of an antisolvent (1,3-propanediol) to a solution of metal salts (Bi/Fe) dissolved in acetic acid results in the formation of nanocrystals (seeds) by supersaturation. The presence of such nanoseeds is also confirmed in the deposited layers, improving significantly the crystallinity of the respective BiFeO 3 thin films as complementary, deduced by piezoresponse force microscopy. Using this low-temperature strategy, crystalline films are directly grown on flexible polymeric substrates at only 350 °C showing a remanent polarization of 10.5 µC cm −2 and a clear photovoltaic effect (11.7 µW cm −2 ) of interest in computer memories and energy harvesters. The flexibility of the BiFeO 3 thin films may enlarge the number of applications of this multifunctional, lead-free material in next-generation digital and sustainable electronic devices based on a facile, low-cost fabrication method with reduced energy consumption.

Innovations in nanogenerator technology foster pervading self-power devices for human use, environmental surveillance, energy transfiguration, intelligent energy storage systems, and wireless networks. Energy harvesting from ubiquitous ambient mechanical, thermal, and solar energies by nanogenerators is the hotspot of the modern electronics research era. Ferroelectric materials, which show spontaneous polarization, are reversible when exposed to the external electric field, and are responsive to external stimuli of strain, heat, and light are promising for modeling nanogenerators. This review demonstrates ferroelectric material-based nanogenerators, practicing the discrete and coupled pyroelectric, piezoelectric, triboelectric, and ferroelectric photovoltaic effects. Their working mechanisms and way of optimizing their performances, exercising the conjunction of effects in a standalone device, and multi-effects coupled nanogenerators are greatly versatile and reliable and encourage resolution in the energy crisis. Additionally, the expectancy of productive lines of future ensuing and propitious application domains are listed.
