Figure 23.

a) Schematic illustration to the structure of all‐solid‐state, coaxial, and integrated fiber device. b–e) “Energy fibers” being bent into various shapes. f) Photoelectric conversion and storage efficiency versus bending for 1000 cycles. η₀ and η correspond to the entire efficiency before and after bending. g) “Energy fibers” being woven into a textile structure with each other. h) Photograph of two “energy fibers” being woven into a flexible aramid fibers textile. The arrow shows the “energy fiber.” Reproduced with permission.247 Copyright 2014, Wiley‐VCH.
