Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks. [PDF]

Adv Sci (Weinh)
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,
