Unraveling Mixed‐Defect Transformations and Passivation Dynamics in Silicon Heterojunction Solar Cells

Advanced Functional Materials, EarlyView.
Defects in materials coexist in multiple forms, undergo dynamic transformations, and influence the material properties. Here, the dynamic transformations of passivation‐related defects in silicon heterojunctions are revealed through the decomposition of dual‐phase capacitance transients.

Entering the Strong Coupling Regime in Conventional Organic Solar Cells

Advanced Functional Materials, EarlyView.
Organic solar cells convert light into fossil‐free energy, yet they still cannot compete with their silicon counterparts. Strong exciton‐photon coupling can ameliorate some properties of organic solar cells, but it requires additional mirrors that diminish light absorbance. Here, mirror‐free strong exciton‐photon coupling is implemented in conventional

Structural and Chemical Studies of the Nanoscale Modifications Induced by Swift Heavy Ion Irradiation in SrTiO3 at Grazing Incidence

Advanced Functional Materials, EarlyView.
The nanoscale structural and chemical transformations in SrTiO3 under Swift‐Heavy‐Ion irradiation at grazing incidence are investigated, emphasizing the formation of well‐ordered nanohillocks at the surface of the material, demonstrating significant material decomposition in the created hillocks with: a phase separation of SrO and TiOx, a reduction in ...

Functionalized Lignin Derivatives as Melt‐Spinnable Precursors for Carbon Fiber Production without Stabilization

Advanced Functional Materials, EarlyView.
By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...
