Highly efficient all-perovskite photovoltaic-powered battery with dual-function viologen for portable electronics.

ABSTRACT: Photovoltaic-powered batteries offer a promising integrated solution for sustainable energy in portable electronics, yet conventional designs face challenges in integration, miniaturization, and flexibility. We address this through a dual-functional, material-sharing strategy using ethyl viologen diiodide to achieve synergistic performance enhancement in photovoltaic-powered batteries. The ethyl viologen diiodide-modified perovskite solar cells exhibit 26.11% efficiency and retain 96.2% of their original performance after 1000 h of continuous use. Batteries employing ethyl viologen diiodide-derived perovskitoid cathodes show 296.1 mAh g-1 at 0.5 A g-1, with a capacity retention of 89% after 10,000 cycles at 5 A g-1. The resulting all-perovskite-based integrated devices show an overall ener
