Organic Ligands Armored ZnO Enhances Efficiency and Stability of CsPbI₂Br Perovskite Solar Cells.

ABSTRACT: Inorganic perovskite solar cells (PSCs) have witnessed great progress in recent years due to their superior thermal stability. As a representative, CsPbI₂Br is attracting considerable attention as it can balance the high efficiency of CsPbI₃ and the stability of CsPbBr₃. However, most research employs doped charge transport materials or applies bilayer transport layers to obtain decent performance, which vastly complicates the fabrication process and scarcely satisfies the commercial production requirement. In this work, all-layer-doping-free inorganic CsPbI₂Br PSCs using organic ligands armored ZnO as the electron transport materials achieve an encouraging performance of 16.84%, which is one of the highest efficiencies among published works.
