    • “The latest research progress shows that adding guanidine acetate to the extraction agent to treat the surface of perovskite can significantly improve the performance and stability of perovskite light-emitting diodes. This strategy effectively reduces surface defects in the perovskite layer, increasing the fluorescence quantum yield from 64% to 79%. The maximum efficiency of the light-emitting diode reaches 11.66%, and the brightness is as high as 1285 cd · m-2, which is significantly better than the untreated reference device.”
