摘要：
Methylammonium lead iodide (CH3NH3PbI3, MAPI) is a high-performance solar cell material but lacks stability in the presence of humidity. Addition of a few percent bismuth (Bi) as a trivalent cation substitute for Pb (i.e., MAP(Bi)I) leads to enhanced stability under high (90%) relative humidity (RH). At moderate humidity (60% RH), however, MAP(Bi)I degrades more rapidly than MAPI. Bi incorporation into MAPI either stabilizes or destabilizes the two hydration products, MAPI center dot H2O and PbI2, depending on the amount of humidity in the environment.
