Solar Cells: Organometal Halide Perovskite Solar Cells with Improved Thermal Stability via Grain Boundary Passivation Using a Molecular Additive (Adv. Funct. Mater. 42/2017)

In article number 1703546, Kilwon Cho and co‐workers demonstrate that PCBM molecules chemically passivate the grain boundaries of organometal halide perovskite crystals. The chemical passivation prevents halogens at the crystal boundaries from exiting from the crystal lattice, and thereby retards th...

Description
Summary:In article number 1703546, Kilwon Cho and co‐workers demonstrate that PCBM molecules chemically passivate the grain boundaries of organometal halide perovskite crystals. The chemical passivation prevents halogens at the crystal boundaries from exiting from the crystal lattice, and thereby retards thermal degradation of the perovskite crystals. The tunability of perovskite grain boundaries by additives is an advance toward the practical use of organometal halide perovskite solar cells.
