Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

Dual‐Wavelength Control of Charge Accumulation in Rubrene Microcrystals with Anisotropic Conductivity

Advanced Science, EarlyView.
Rubrene microcrystals, forming two distinct sector types, are investigated using photoemission electron spectroscopy. The two sectors exhibit a built‐in charge landscape, arising from anisotropic conductivities. Upon excitation with UV light, the diamond‐shaped sectors accumulate significant charge, whereas the triangular sectors remain essentially ...
