A Novel Supercapacitor with Integrated Photosensitive Electrode to Enhance Its Capacitance Under Solar Light

Small, Volume 22, Issue 13, 3 March 2026.
In this research we demonstrated that the energy density of supercapacitors can be enhanced at about 50% by generating extra charge through the use of a photosensitive cell coupled to the supercapacitor estructure. ABSTRACT This research reports a supercapacitor (SC) made with a photosensitive electrode (composed of LaFe0.94V0.01Mn0.05O3 (V‐LFO ...
