Abstract

= 0.4 yields optimal photovoltaic performance under ambient conditions and the lowest photovoltage deficit. Our analysis of the charge recombination processes indicates that structural disorder and band alignment act as competing factors governing the photovoltage deficit. This study elucidates how compositional engineering fine-tunes the optoelectronic properties of perovskites and provides insights into developing novel Pb-Sn binary PSCs with near-optimal bandgaps.
