Summary: To solve the problems of uncontrollable crystallization process and facile oxidation of Sn2+, a series of acetates are introduced into the perovskite precursor solution. Formamidine acetate (FAAc) is found to have strong C(sic)O-Sn coordination with Sn2+, which can stabilize the lattice structure, minimize defect states, and suppress the oxidation of Sn2+. By introducing FAAc into the precursor, the power conversion efficiency of the device is increased from initially 9.84% to 12.43%, and it can maintain 94% of its initial value for 2000 hours in N2 atmosphere. This work provides a feasible strategy for depositing high-quality tin perovskite films, which is crucial for related photovoltaics and other optoelectronic devices.

Summary: This study molecularly explored the chemistry of perovskite precursor solutions for the first time using in situ liquid time-of-flight secondary ion mass spectrometry. It identified that methylammonium, formamidinium cations, and I- anion are the drivers of aging chemistry.
