Buried Interface Dielectric Layer Engineering for Highly Efficient and Stable Inverted Perovskite Solar Cells and Modules (Adv. Sci. 19/2023)

Perovskite Solar Cells The voids at the buried interface of perovskite result in severe non‐radiative recombination. The dielectric Al(2)O(3) nanoparticles are introduced imbedding into these voids, leading to compact and flat morphology, hampered recombination and improved collection of carriers, which contributes to significant increase in V (OC) and stability. The dielectric layer engineering reveals a promising prospect in developing high‐performance perovskite solar cells and modules.
