We present a critical review that encompasses the fundamentals and state-of-the-art
knowledge of barium titanate-based piezoelectrics. First, the essential crystallography …

Inorganic metal oxide electron‐transport layers (ETLs) have the potential to yield perovskite
solar cells with improved stability, but generally need high temperature to form conductive …

Triboelectrification for contacts between three types of materials—metals, polymers, and
semiconductors—are investigated. The results show that triboelectrification is a charge …

With power conversion efficiencies now exceeding 25%, hybrid perovskite solar cells
require deeper understanding of defects and processing to further approach the Shockley …

In this work, the evolution behavior of electrocaloric effect in BaTiO3‐based ceramics with
different phase structures and phase transitions was compared. A paradigmatic system of …

In this study, the stress-modulated energy storage properties of lead-free polycrystalline Ba
0.85 Ca 0.15 Zr 0.1 Ti 0.9 O 3 was investigated as a function of temperature from 25° C to …

For high-resolution powder diffraction in material science, high photon energies are
necessary, especially for in situ and in operando experiments. For this purpose, a multi …

Neutron powder diffraction was used in operando to determine the macroscopic strain and
piezoelectric coefficient as a function of applied electric field in a technically relevant …

Microstructural design is a widespread approach to tailor the properties of functional
materials with the size effect being an effective constraint that modifies physical phenomena …

While BiFeO3-based solid solutions show great promise for applications in energy
