Large tunable photoeffect on ion conduction in halide perovskites and implications for photodecomposition

The ionic conductivity of methylammonium lead iodide is enhanced up to two orders of magnitude when the material is exposed to light. This effect may also have implications for the photostability of perovskites.

Roll-to-roll gravure-printed flexible perovskite solar cells using eco-friendly antisolvent bathing with wide processing window

Driven by recent improvement in efficiency and stability of perovskite solar cells, the next step toward commercialisation is upscaling. Here, the authors demonstrate pilot-scale fully roll-to-roll manufacturing of flexible perovskite solar cells through gravure-printing and antisolvent bathing.

A fluorene-terminated hole-transporting material for highly efficient and stable perovskite solar cells

Interfacial losses between device layers play a key role in determining characteristics of solar cells. Jeon et al. address this in perovskite solar cells by synthesizing a hole-transporting layer that is better matched to the surrounding layers, and show high-efficiency and high-stability devices.

Tyrosine-mediated two-dimensional peptide assembly and its role as a bio-inspired catalytic scaffold

It is well known that the interplay between molecular ordering and interface geometry can determine the morphology of two-dimensional systems. Here, the authors report facet formation in water droplets, driven by peptide assembly, and investigate the structural and sequence motifs that affect this behaviour.

Efficient, stable and scalable perovskite solar cells using poly(3-hexylthiophene)

A double-layered halide architecture for perovskite solar cells enables the use of dopant-free poly(3-hexylthiophene) as a hole-transport material, forming stable and scalable devices with a certified power conversion efficiency of 22.7 per cent.
