Progress Toward Efficient Wide‐Gap Cu(In,Ga)(S,Se)2 Thin‐Film Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
Wide‐gap Cu (In,Ga)(S,Se)2 thin‐film solar cells are studied in view of their performance, limitations, and opportunities for further optimization. Different sources of open circuit voltage limitations were discussed and weighted. Interface recombination appears the main recombination channel, which however can be influenced heavy alkali treatment ...

Wet‐Transferred MoS2 on Passivated InP: A Van der Waals Heterostructure for Advanced Optoelectronic Applications

physica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 5, May 2025.
This study presents a photodetector based on atomically thin MoS2 on an InP substrate, forming an n‐MoS2/p‐InP type‐II staggered heterojunction. The device exhibits excellent rectifying properties with an ideality factor of 1.57 and achieves a peak photoresponsivity of 960 mA W−1, while MoS2 provides stable passivation for InP. III–V semiconductors are

The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

Responsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

Orthogonal Tri‐Modular Coiled‐Coil Assembly for Programmable Multi‐Cargo Display on Escherichia coli Nissle 1917

Small, EarlyView.
A tri‐specific scaffold cell (TriSC) platform is engineered to enable programmable, reversible, and multiplex surface assembly through orthogonal and spontaneous coiled‐coil interactions. Independent targeting and therapeutic nanobodies are modularly recruited onto bacterial surfaces, allowing tunable combinatorial functionality.
