Quantum dot (QD) and halide perovskite solar cells (PSCs) represent two fast-evolving routes to high-efficiency, low-cost photovoltaics. Both systems share exceptional optical absorption and tunable bandgaps, but differ in dominant charge-transport physics: QD films usually show hopping-like, ligand-limited transport with strong effects from interparticle coupling and ligand chemistry, while perovskites often exhibit band-like transport with long diffusion lengths but are highly sensitive to ionic motion and defect-mediated trap recombination. This review synthesizes the charge-generation, transport, recombination, and interfacial processes that control device performance in QD and perovskite solar cells, summarizes common characterization methods (SCLC, TRPL, transient absorption, impedance spectroscopy, KPFM), and discusses strategies—ligand engineering, passivation, band-alignment design, and transport-layer optimization to mitigate loss mechanisms and improve collection efficiency. Key open questions and promising research directions are highlighted.
