Bulk recrystallization for efficient mixed-cation mixed-halide perovskite solar cells

Today, the use of mixed-cation lead mixed-halide perovskite with a slight excess of lead iodide (PbI 2 ) demonstrates the highest device performances in the literature. However, the presence of excess PbI 2 in the film poses long-term stability concerns. Here, we propose a facile bulk recrystallizat...
