Quantum-Size-Tuned Heterostructures Enable Efficient and Stable Inverted Perovskite Solar Cells

Bulkier organic spacers slow 2D heterostructure formation to produce wider (n ≥ 3) reduced-dimensional perovskites that eliminate electron blocking at the 2D/3D interface, enabling certified 23.91% inverted perovskite solar cells stable at 50% relative humidity for >1000 h.
