Abstract Organic-inorganic lead halide perovskites are a new class of semiconductor materials with great potential in photocatalytic hydrogen production, however, their development is greatly plagued by low activity, instability organic component and toxicity particular. Herein, we report an anti-dissolution environmentally friendly Cs 2 SnI 6 perovskite anchored atomically dispersed Pt-I 3 species (PtSA/Cs ) for achieving the highly efficient production HI aqueous solution at room...
Defects, inevitably produced within bulk and at perovskite-transport layer interfaces (PTLIs), are detrimental to power conversion efficiency (PCE) stability of perovskite solar cells (PSCs). It is demonstrated that a crosslinkable organic small molecule thioctic acid (TA), which can simultaneously be chemically anchored the surface TiO2 methylammonium lead iodide (MAPbI3 ) through coordination effects then in situ crosslinked form robust continuous polymer (Poly(TA)) network after thermal...
The inherent brittleness of ceramics, primarily due to restricted atomic motions from rigid ionic or covalent bonded structures, is a persistent challenge. This characteristic hinders dislocation nucleation in thereby impeding the enhancement plasticity through dislocation-engineering strategy commonly used metals. Finding that continuously generates dislocations within ceramics may enhance plasticity. Here, we propose "borrowing-dislocations" uses tailored interfacial structure with...
