초록

Perovskite quantum dots (PQDs) have attracted significant attention as promising photovoltaic materials due to their unique optoelectronic properties, defect tolerance, and facile solution processing. Since the first report of PQD solar cells in 2016 with 10.77% efficiency, rapid development has been achieved, with recent certified values exceeding 19%. A key factor in this development is the control of initial long-chain ligands that must be replaced or removed to enable efficient charge transport. Because ligand binding strength and exchange behavior differ depending on the A-site cation, tailored strategies have been developed for inorganic Cs-based, organic FA/MA-based, and mixed cation PQDs. These efforts have led to steady improvements in device efficiency and stability. This review highlights recent advances in ligand engineering with respect to A-site composition and discusses remaining challenges for high-performance, scalable PQD solar cells.
