Effective carrier management in perovskite solar cells via ferroelectric polarization
Carrier management is a critical factor influencing the photovoltaic performance of perovskite solar cells (PSCs). The incorporation of ferroelectric materials into PSCs enhances both carrier management and photovoltaic performance. In this work, the SnO2–BiFeO3 electron transport layer (ETL) is polarized under externally applied electric field, inducing a ferroelectric polarization (P) in BiFeO3, which modifies the built-in potential (Vbi) of PSCs, thereby significantly controlling the carrier transport rate and direction. By employing the polarized SnO2–BiFeO3 ETL, MAPbI3 PSCs exhibit an 11.03% increase in power conversion efficiency compared to its control counterpart, demonstrating the effectiveness of ferroelectric polarization in enhancing carrier management in PSCs.
