| 英文摘要 | Even though a record efficiency of 23.3% has been achieved in organic-inorganic hybrid perovskite solar cells, their stability remains a critical issue, which greatly depends on the morphology of perovskite absorbers. herein, we report a practical grain boundary modification to remarkably improve the humidity and thermal stability by gradually growing in situ two-dimensional nanoplates between the grain boundaries of perovskite films using phenylethylammonium iodide (peat). the experimental results show that peal nanoplates play a critical role in stabilizing perovskite thin films by reducing the moisture sensitivity and suppressing phase transition at the grain boundaries. in addition to the significant improved ambient stability, the grain boundary modification by peal can effectively suppress the nonradiative charge recombination at grain boundaries. as a result, the efficiency of perovskite solar cells is up to 20.34% with significant humidity and thermal stability. |
