Prussian blue regulates ion dynamics in perovskite solar cells
As perovskite films form, poorly controlled crystallization can produce structural defects and internal strain. Once the cells are operating, ions can migrate through the material under light, heat, and electric fields, further contributing to degradation and making it difficult…
This strategy achieved a power conversion efficiency (PCE) of 26.9% in small-area cells and was further validated at larger scales, reaching 23.4% in 6 cm × 6 cm minimodules and a certified efficiency of 22.9% in 30 cm × 30 cm perovskite submodules.

PSCs have attracted considerable attention for their outstanding photovoltaic performance and potential for large-scale applications.
