Abstract

Abstract: Ideal bandgap ~ 1.4 eV of lead–tin (Pd–Sn) organic–inorganic hybrid perovskite absorber is essential to further enhance the power conversion efficiency of perovskite solar cells (PVSCs). However, due to the facile oxidation of Sn²⁺, large amount of Sn substituted Pb based PVSCs suffer with low stability in ambient environment. In this work, we realize an ideal bandgap perovskite by introducing a small amount (10 mol%) of Sn²⁺ to methylammonium lead iodide (MAPbI₃). A large grain size MAPb_0.9Sn_0.1I₃ films with strong absorbance can be obtained. As a result, the best performance up to 18.3% efficiency is achieved. Importantly, the MAPb_0.9Sn_0.1I₃ cell retains 90% of its performance after operation at the maximum power point under full 1-sun illumination for 500 h, in contrast to the quick degradation of MAPbI₃ cell. This study demonstrates the promising potential of stable and efficient ideal band-gap Pb–Sn PVSCs. Graphic Abstract: [Figure not available: see fulltext.].
