Bimolecularly Passivated Interface Enables Efficient and Stable Inverted Perovskite Solar Cells
Published in Science 2023, 382 (6672), 810–815, 2023
A sulfur-modified methylthio molecule provides chemical defect passivation through strong coordination and hydrogen bonding, while a diammonium molecule repels minority carriers via field-effect passivation, together yielding a certified 25.1% quasi-steady-state PCE and stable operation at 65 °C for >2000 h in ambient air.
