Abstract

A wire-shaped energy device that can perform photoelectric conversion and electrochemical storage was developed through a simple but effective twisting process. The energy wire exhibited a high energy conversion efficiency of 6.58 % and specific capacitance of 85.03 μF cm(-1) or 2.13 mF cm(-2), and the two functions were alternately realized without sacrificing either performance.
