Charge Generation and Recombination Pathways in All‐Polymer Bulk Heterojunction Solar Cells
Multimodal spectroscopy and device analysis reveal how field‐dependent charge generation, transport limitations, and non‐geminate recombination govern performance losses in all polymer solar cells. The results identify the key processes controlling charge extraction and recombination, providing insights for the design of more efficient all‐polymer ...

Effective control over the crystalline contact plane and microstructure of a naphthalenediimide‐bithiazole copolymer enables high‐performance n‐type thermoelectrics. While rubbing alignment induces a detrimental edge‐on orientation, subsequent solvent vapor‐induced re‐orientation facilitates a favorable mixed face‐on/edge‐on morphology.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...
