Ligand Assisted Epitaxial Growth of CsPbBr3 Microcrystal Resonators With Record ‐Low Lasing Thresholds

Advanced Functional Materials, EarlyView.
Solution‐based ligand‐assisted epitaxial growth (LAEG) yields high‐quality CsPbBr3 microcrystals on different substrates with superior morphology, passivated surfaces, and high photoluminescence quantum yield. These robust micro‐resonators achieve record‐low room‐temperature lasing thresholds of 7.2 kW·cm−2 and maintain operational stability up to 90 ...

Dye-sensitized solar cells with 13% efficiency achieved through the molecular engineering of porphyrin sensitizers [PDF]

, 2014
Dye-sensitized solar cells have gained widespread attention in recent years because of their low production costs, ease of fabrication and tunable optical properties, such as colour and transparency. Here, we report a molecularly engineered porphyrin dye,

Reaction‐Time pH Stabilization by Poly(acrylic acid) with Ethanol‐Mediated Growth Control for Efficient Hydrothermal Sb2(S,Se)3 Solar Cells

Advanced Functional Materials, EarlyView.
Poly(acrylic acid) acts as a reaction‐time pH buffer during hydrothermal Sb2(S,Se)3 growth through its COOH/COO‐ equilibrium. When combined with ethanol‐regulated growth, this buffering strategy reduces Sb‐O related surface disorder, improves local electronic uniformity and carrier collection, and increases the champion solar‐cell efficiency to 10.25%,

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays

Advanced Functional Materials, EarlyView.
Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.
