摘要: The effects of the environment on the energy storage of supercapacitors as well as the underlying mechanisms have long been neglected. This paper reports that the capacitance of hexagonal‐phase tungsten oxide (h‐WO3)‐based supercapacitors increases by≈ 17% under solar light. Thorough analyses of the wavelength dependence of the enhancement, capacitive mechanism, energy storage dynamics, and impedance reveal that: i) photoexcited electrons are responsible for the enhancement; ii) the insertion of protons into …
