Grain Boundary Engineering with Self-Assembled Porphyrin Supramolecules for Highly Efficient Large-Area Perovskite Photovoltaics
Published in Journal of the American Chemical Society 2021, 143 (45), 18989–18996, 2021
NiP porphyrin supramolecules self-assemble at perovskite grain boundaries, where organic cations convert them into hole-transporting ammonium porphyrins that simultaneously passivate defects and promote inter-grain hole transport, yielding certified 22.1% PCE on 1.0 cm2 with stability exceeding 3000 h under illumination or at 85 °C.
