Polymer solar cells based on fullerene acceptors have reached in recent years power
conversion efficiencies (PCEs) approaching 13%. The advent of non-fullerene acceptors …

This review attempts to compile the physics and chemistry of defects in zinc oxide (ZnO), at
both, the fundamental and application levels. The defects, either inherent ones or introduced …

Achieving high-efficiency indium tin oxide (ITO)-free organic optoelectronic devices requires
the development of high-conductivity and high-transparency materials for being used as the …

Positron annihilation spectroscopy is particularly suitable for studying vacancy-type
defects<? format?> in semiconductors. Combining state-of-the-art experimental and …

Positron is the only probe that can detect individual atomic vacancies and small and large
vacancy clusters induced by irradiation with remarkable sensitivity, providing information …

In recent years, there has been increasing interest in ZnO nanostructures due to their variety
of morphologies and availability of simple and low cost processing. While there are still …

Zn metal anodes with fast kinetics and stable thermodynamics is critical for developing
reversible high-performance aqueous Zn-ion batteries. Herein, based on the characteristic …

Zinc oxide (ZnO) is a wide band gap semiconductor with potential applications in
optoelectronics, transparent electronics, and spintronics. The high efficiency of UV emission …

Contemporary theories of defects and impurities in semiconductors rely to a large extent on
supercell calculations within density-functional theory using the approximate local-density …

In this study, three different morphologies, nanoflower (NF), nano sponge (NS), and nano
urchin (NU), of zinc oxide (ZnO) nanostructures were synthesized successfully via a mild …
