Photocatalysis-Assisted Co₃O₄/g-C₃N₄ p-n Junction All-Solid-State Supercapacitors: A Bridge between Energy Storage and Photocatalysis.

ABSTRACT: Supercapacitors with the advantages of high power density and fast discharging rate have full applications in energy storage. However, the low energy density restricts their development. Conventional methods for improving energy density are mainly confined to doping atoms and hybridizing with other active materials. Herein, a Co₃O₄/g-C₃N₄ p-n junction with excellent capacity is developed and its application in an all-solid-state flexible device is demonstrated, whose capacity and energy density are considerably enhanced by simulated solar light irradiation. Under photoirradiation, the capacity is increased by 70.6% at the maximum current density of 26.6 mA cm^-2 and a power density of 16.0 kW kg^-1. The energy density is enhan
