Fotobaterías, fotoelectrodo, heterounión, TiO₂–Fe₂O₃, almacenamiento de energíaResumen
Las fotobaterías permiten convertir y almacenar energía solar en un mismo dispositivo. En este trabajo se evaluó una fotobatería de ion-litio con un electrodo TiO₂–Fe₂O₃ (1:1) preparado por mezcla mecánica. Mediante técnicas como DRX, SEM, UV–Vis y Mott–Schottky se confirmó la formación de una heterounión que mejora la separación de cargas y la absorción de luz visible. Bajo iluminación (1 sol), la capacidad aumentó de 160 a 220 mAh g⁻¹. Este efecto se asocia a la generación de cargas fotoinducidas que favorecen las reacciones electroquímicas, mostrando el potencial del material para aplicaciones energéticas.
