In crystalline and amorphous semiconductors, the temperature-dependent Urbach energy
can be determined from the inverse slope of the logarithm of the absorption spectrum and …

The extensive use of perovskites as light absorbers calls for a deeper understanding of the
interaction of these materials with light. Here, the evolution of the chemical and …

In terms of sustainable use, halide perovskite (HaP) semiconductors have a strong
advantage over most other classes of materials for (opto) electronics, as they can self-heal …

Two‐step sequential deposition of perovskite films is proven efficient and compatible with
large‐scale production. Nevertheless, its critically regulated environmental humidity often …

Defects in metal halide perovskites (MHP) are photosensitive, making the observer effect
unavoidable when laser spectroscopy methods are applied. Photoluminescence (PL) …

Recovery from damage in materials helps extend their useful lifetime and of devices that
contain them. Given that the photodamages in HaP materials and based devices are shown …

Humidity is often reported to compromise the stability of lead halide perovskites or of devices
based on them. Here we measure the humidity dependence of the elastic modulus and …

Compared with conventional semiconductors, halide perovskite nanocrystals (NCs) have a
unique crystal structure and outstanding optoelectronic properties, offering wide potential for …

The performance and stability of organic–inorganic hybrid perovskite solar cells (PSCs) are
highly sensitive to water and moisture in the surrounding environment. Understanding how …

Halide perovskites solar cells (PSCs) are making true on past promises, having reached
power conversion efficiencies (PCEs) of 25.7% and long lifespans (> 3000 h). Although …
