A green solvent processable, self‐doped N‐annulated perylene butyl tetraester applied as a solar cell cathode interlayer

Polymer International, EarlyView.
A new organic molecular cathode interlayer is presented built upon the perylene butyl tetraester scaffold. The new molecule incorporates N‐annulation and a functional amine group to control optical, electrochemical and physical properties and delivers excellent solar cell performance. Abstract We report a new amino‐bay‐substituted, N‐annulated perylene

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

Mixed TiO2–SiO2 thin coatings for selective adsorption and sunlight‐powered photodegradation of cationic pollutants

Responsive Materials, EarlyView.
Environmental pollution and water scarcity demand innovative purification methods. This study presents a sol‐gel approach to fabricate mixed silica–titania thin films joining photocatalytic activity with selective sorption capability. The films exhibit higher surface area, enhanced degradation of cationic and improved performance over bare titania ...

Laser‐Direct Printed 2D Material‐Based Heterostructure for the Fabrication of Electronic Devices

Small, EarlyView.
The Digital Laser‐Induced Forward Transfer (LIFT) approach is employed to pattern and stack 2D materials with micrometer‐scale precision. PdSe2 and MoSe2 are assembled into vertical p–n junctions, with graphene serving as a transparent electrode. The resulting laser‐transferred heterostructures exhibit high material quality and stable rectifying ...
