TL;DR: In this article, a low-temperature solution-processed ZnO nanorod (NR) array exhibiting higher NR aspect ratio, enhanced electron density, and substantially reduced work function was developed for mesoscopic perovskite solar cells.

TL;DR: This work presents a new method based on blade coating of a blend of conjugated small molecules and amorphous insulating polymers to produce OTFTs with consistently excellent performance characteristics, demonstrating that careful control over phase separation and crystallization can yield solution-printed polycrystalline organic semiconductor films with transport properties and other figures of merit on par with their single-crystal counterparts.

TL;DR: Cyclic voltammetry, UV-vis absorption, and ultraviolet photoelectron spectroscopy are used to characterize hole energy levels in the polymer phases of polymer:fullerene bulk heterojunctions to improve charge separation and reduce recombination in polymer solar cells (PSCs).

TL;DR: In this article, tungsten trioxide (WO3)-based nanostructured and porous ETL materials directly grown hydrothermally with different morphologies such as nanoparticles, nanorods and nanosheet arrays were explored.

TL;DR: ‘lattice-anchored’ hybrid materials that combine caesium lead halide perovskites with lead chalcogenide CQDs are reported, in which lattice matching between the two materials contributes to a stability exceeding that of the constituents.
