Novel perovskite-based betavoltaic cell: dual additive strategy for enhanced FAPbI3 α-phase stability and performance

Abstract

By utilizing chlorine-based dual additives with perovskite film and radioactive isotopes of carbon nanoparticle/quantum dot (14CNP/CQD) electrodes, we enhanced the phase stability and power conversion efficiency (PCE) of the betavoltaic device. This study represents the first successful integration of perovskite into a betavoltaic cell, pioneering perovskite betavoltaic cells (PBCs).
