Dual-Site Synergistic Passivation for CsPbBr3 Perovskite Solar Cells with Record 1.707 V Voc and 11.23% Efficiency

Achieving high-quality perovskite films with minimal defect states is critical for the development of efficient and stable perovskite solar cells (PSCs). In this work, we introduce diphenylphosphine (DPP) additives into...
