Solvated Palladium (II) Complexes for Efficient and Stable All-Inorganic CsPbI2Br Perovskite Solar Cells

In this work, a solvated palladium (Pd) complex, PdBr2(PhCN)2 was added into perovskite precursor ink to not only stabilizes the α-phase of CsPbI2Br perovskite owing to Pd2+ ions, but also effectively improves the perovskite film morphology. The photovoltaic device with PdBr2(PhCN)2 shows substantially enhanced environmental and operational stabilities. This data set contains the optoelectronic, morphological (SEM, AFM) compositional characterization of the resulted thin films (solid state NMR) and photovoltaic properties of the fabricated solar cells (J-V curves, EQE, carrier recombination, power conversion efficiency) together with their stability at different conditions. The resulting perovskite films were also characterized by steady-state photoluminescence (PL), time-resolved PL (TRPL) and electrochemical impedance spectroscopy (EIS) measurements.
