TL;DR: In this paper, the authors demonstrate cesium cation (Cs+) doped 2D (BA)2(MA)3Pb4I13 perovskite solar cells giving a power conversion efficiency (PCE) as high as 13.7%.

TL;DR: Using phase-separated organic semiconducting blends containing a small molecule, as the hole transporting material, and a conjugated amorphous polymer as the binder material, the authors demonstrate solution-processed organic thin-film transistors with superior performance characteristics that include; hole mobility >5 cm(2) /Vs, current on/off ratio ≥10(6) and narrow transistor parameter spread.

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: It is demonstrated that pressure processing can serve as a novel approach for the rapid conversion of lead halide perovskite nanocube superlattices into structures with enhanced properties.

TL;DR: The first direct observation of photoactive layer formation as it occurs during spin-coating is reported, providing new insight into mechanisms and kinetics of bulk heterojunction formation, which may be crucial for its successful transfer to scalable printing processes.
