Clean‐Limit 2D Superconductivity in a Thick Exfoliated Kagome Film

open access: yesAdvanced Functional Materials, EarlyView.
This study reports clean‐limit 2D superconductivity in a thick kagome system, analogous to the 3D case. It observes a drop in superfluid stiffness near the superconducting transition and a cusp‐like feature in the angular dependence of the upper critical field.

Power enhancement of PV arrays in different configurations under different partial shaded condition

open access: yesScientific Reports
Among the most sustainable forms of energy, solar energy delivers clean, dependable, and limitless power. However, the PV arrays experience uneven irradiance as a result of partial shadowing situations, which causes several peaks in their PV ...

Spin analysis of concentrated traction contacts [PDF]

open access: yes
Spin, the result of a mismatch in contact radii on either side of the point of rolling, has a detrimental effect on traction contact performance. It occurs in concentrated contacts having conical or contoured rolling elements, such as those in traction ...

High‐Rate FA‐Based Co‐Evaporated Perovskites: Understanding Rate Limitations and Practical Considerations to Overcome Their Impact

open access: yesAdvanced Functional Materials, EarlyView.
Vacuum‐based deposition is promising for perovskite solar cells to be successfully commercialized. However, co‐evaporation, the most common vapor phase deposition technique, suffers from very low deposition rates. In this work, we reveal that high deposition rates can lead to carbon flakes depositing into the perovskite absorber layers due to material ...

Modeling the electrical mismatch caused by potential-induced degradation in crystalline silicon photovoltaic modules and strings

open access: yesEPJ Photovoltaics
Potential-induced degradation (PID) can not only reduce the output power of a solar cell but also create additional power losses due to non-uniform degradation within a module, string or array, leading to mismatch in the electrical performance of the ...

Electrochemical Formation of BiVO4/BiPO4 Photoanodes for Enhanced Selectivity toward H2O2 Generation

open access: yesAdvanced Functional Materials, EarlyView.
In acidic KPi, V dissolves from the BiVO4 lattice, while adsorbed phosphate reacts with the electrode under an external bias, forming a BiPO4 surface layer. This BiPO4 layer exhibits stronger bicarbonate adsorption, redirecting the water oxidation pathway toward two‐electron H2O2 production.
