Abstract With a certified efficiency as high 25.2%, perovskite has taken the crown highest thin film solar cell material. Unfortunately, serious instability issues must be resolved before cells (PSCs) are commercialized. Aided by theoretical calculation, an appropriate multifunctional molecule, 2,2‐difluoropropanediamide (DFPDA), is selected to ameliorate all issues. Specifically, carbonyl groups in DFPDA form chemical bonds with Pb 2+ and passivate under‐coordinated defects. Consequently,...
Cytochromes P450 (CYPs) play a key role in generating the structural diversity of terpenoids, largest group plant natural products. However, functional characterization CYPs has been challenging because expansive families found genomes, diverse reactivity and inaccessibility their substrates Here we present two CYPs, CYP76AH3 CYP76AK1, which act sequentially to form bifurcating pathway for biosynthesis tanshinones, oxygenated diterpenoids from Chinese medicinal Danshen (Salvia miltiorrhiza)....

At optimal CsAc alloying, PSCs achieve a maximum power conversion...
Single-crystalline ZnSe nanowires (NWs, see Figure) are fabricated on GaAs substrates using a Au-catalyzed vapor–liquid–solid mechanism. The as-grown NWs display size- dependent growth direction properties that interpreted based the estimation of surface and interface energies NW. solid/ liquid structure at tip NW is most critical factor influencing direction.
In planar perovskite solar cells (PSCs), defect‐induced recombination at the interface between and hole transport layer (HTL) leads to a large potential loss performance deterioration. Therefore, an effective method for improving interfacial properties is critical boost stability of PSCs.

Electrically interfacing atomically thin transition metal dichalcogenide semiconductors (TMDSCs) with leads is challenging because of undesired interface barriers, which have drastically constrained the electrical performance TMDSC devices for exploring their unconventional physical properties and realizing potential electronic applications. Here we demonstrate a strategy to achieve nearly barrier-free contacts few-layer TMDSCs by engineering interfacial bonding distortion. The...
