Dicyandiamide-Driven Tailoring of the n-Value Distribution and Interface Dynamics for High-Performance ACI 2D Perovskite Solar Cells (IMAGE)
Caption
- Guanidine derivatives of dicyanodiamide (DCD) is introduced into the buried interface of quasi-2D alternating-cation-interlayer perovskites (GA(MA)nPbnI3n+1), which simultaneously realize the defect passivation of buried interface and the regulation of phase distribution.
- This interface engineering not only reduces interfacial defects but also enhances the interfacial charge transfer, and the DCD-regulated perovskite solar cells exhibit a significant increase in efficiency from 19.05% to 21.54%.
