摘要：Multijunction photovoltaics (PVs) are gaining prominence owing to their superior capability of achieving power conversion efficiencies (PCEs) beyond the radiative limit of single-junction cells1, 2, 3, 4, 5, 6, 7-8, for which improving narrow-bandgap (NBG) tin-lead perovskites is critical for thin-film devices9. Here, with a focus on understanding the chemistry of tin-lead perovskite precursor solutions, we find that Sn(ii) species dominate interactions with precursors and additives and uncove...
