However, instability of perovskite under vacancy defects and stress\u2013strain makes it difficult to achieve high\u2010efficiency and stable power output. Here, a soft\u2010structured long\u2010chain 2D pentanamine iodide (abbreviated as \u201cPI\u201d) is used to improve perovskite quality and interfacial mechanical compatibility.

Consequently, photoelectric conversion efficiency (PCE) of optimal device is enhanced from 10.85% to 13.76% and operational stability is also significantly improved. 83.1% output is maintained after aging for 720\u00a0h at room temperature and 25\u201360% relative humidity (RH).
