Herein, we demonstrate that thermal-evaporated SAMs (eSAMs) overcome this limitation by enabling precise thickness control. Crucially, a thickened eSAM spontaneously forms a vertical-to-horizontal gradient in molecular orientation, which creates a descending energy barrier that directionally facilitates hole transport. This tailored interface also ensures excellent surface coverage and directs the growth of high-quality perovskite films. Consequently, the resultant photovoltaic devices set new benchmarks, delivering impressive power conversion efficiencies (PCEs) of 21.46% (small-area, 0.108 cm<sup>2</sup>) and 19.38% (large-area module, 15.52 cm<sup>2</sup>) for fully vacuum-evaporated devices, while also setting an impressive PCE of 23.67% for eSAM-based devices with solution-processed perovskites.

In this tutorial-style perspective, we seek to emphasize the importance of adopting a multi-technique approach to stability characterization and outline protocols for the rigorous characterization of four major classes of stability in MOFs: thermal, chemical, mechanical, and radiation.
