Reinforcement of Cathode Interface Using a Dipolar Small Molecule for Enhancing Operational Stability of Perovskite Solar Cells

Advanced Science, EarlyView.
We report a high‐dipole interlayer, MQPPO, that simultaneously improves efficiency and stability in perovskite solar cells. Its strong interfacial dipole enhances photovoltaic performance, while its uniform coverage and strong interaction with Ag effectively suppress AgI formation, ensuring long‐term stability under moisture and thermal stress.

Study of ohmic contact at Ti/ZnO interface by using electrical characteristics and KPFM analysis

Discover Materials
Abstract In this paper, a negative barrier height at the interface of ZnO/Ti was studied using Kelvin probe force microscopy (KPFM) analysis. This result agrees with the metal-semiconductor Ohmic contact theory. Without any dopant, the pure ZnO thin films were deposited over integrated circuit compatible SiO2/p-Si silicon by the radio ...

Dynamic Hydrogen‐Bonding Nanonetworks and Asymmetric Dual‐Interface Built‐In Electric Fields Cooperatively Mediate Proton‐Coupled Electron Transfer for C─H Activation

Advanced Science, EarlyView.
The general strategy for constructing proton–electron dual‐transport‐channel photocatalysts (hollow Co3S4/Sv‐chalcogenide/Ti3C2 nanoreactors) is developed. Theses ternary‐component nanoreactors feature dynamic hydrogen‐bonding nanonetworks as proton‐transport channels and asymmetric dual‐interface BIEFs as electron‐transport channels, serving as a ...

Surface Engineering on Transition Metal Dichalcogenides: In Situ Encapsulation of Metal–Organic Frameworks for Highly Humidity‐Resistant Gas Sensing at Room Temperature

Advanced Science, EarlyView.
2D UiO‐66‐NH2/MoS2 was fabricated via an aqueous synthesis method to in situ encapsulation of MoS2 with 2D UiO‐66‐NH2 MOF. The humidity‐resistant NO2 sensing of 2D UiO‐66‐NH2/MoS2 at room temperature was accordingly enhanced by MOF encapsulation layer, along with the selectivity and stability.

Diffusion‐Driven Targeted Passivation of Selenium Vacancies via an I‐Doped CdS Buffer Layer for Efficient Sb2Se3 Solar Cells

Advanced Science, EarlyView.
Iodine incorporation into the CdS buffer layer induces spontaneous anion diffusion and selectively passivates selenium vacancies in Sb2Se3 absorbers. The formation of low‐energy, charge‐neutral ISe defects effectively suppresses non‐radiative recombination, resulting in a substantially enhanced open‐circuit voltage and boosting the device efficiency to
