The oxygen evolution reaction (OER) is a crucial process in electrochemical water splitting,
a promising technology to renewably yield hydrogen gas from water. Designing and …

The bulk photovoltaic effect (BPVE) refers to the generation of a steady photocurrent and
above-bandgap photovoltage in a single-phase homogeneous material lacking inversion …

Van der Waals interfaces can be formed by layer stacking without regard to lattice constants
or symmetries of individual building blocks. We engineered the symmetry of a van der Waals …

Shift current is a steady-state photocurrent generated in non-centrosymmetric single crystals
and has been considered to be one of the major origins of the bulk photovoltaic effect. The …

The recent development of artificially fabricated van der Waals nanostructures makes it
possible to design and control the symmetry of solids and to find novel physical properties …

Metal chalcogenide perovskites were proposed as potential solar cell material in 2015. The
theoretical maximum solar cell efficiencies of some chalcogenide perovskites are∼ 30 …

Perovskites have been significantly considered as promising materials for electrochemical
energy storage in the recent years. Co-doping of Mn and Nd with hydrothermally …

Photoexcitation in solids brings about transitions of electrons/holes between different
electronic bands. If the solid lacks an inversion symmetry, these electronic transitions …

Improving the efficiency of charge separation (CS) and charge transport (CT) is essential for
almost all optoelectronic applications, yet its maximization remains a big challenge. Here we …

Bismuth ferrite BiFeO3 (BFO) is an important ferroelectric material for thin-film optoelectronic
