Novel Method to Prepare Perovskite MAPb_0.75Sn_0.25I₃ Solar Cells with Sn²⁺/Sn⁴⁺ Oxidation Mitigation via Molarity Reduction in a Non-Inert Atmosphere Processing

Sn-based perovskites offer lower lead content but face a major challenge: Sn²⁺ oxidizes readily, which has led most research groups to use gloveboxes and chemical additives during processing. Here, we investigate whether precursor molarity alone can mitigate this oxidation problem in ambi...
