摘要：

Lead halide perovskite solar cells show poor stability due to their ionic material character. Here, we introduce a dipping method to modify the perovskite layer with 3-hydroxypyridine molecules. The long-term stability of solar cells is greatly enhanced and shows no obvious decay after 90 hour steady-state measurements.
