The news correspondents obtained a quote from the research, "Compared to devices with polyethylene dioxythiophene polystyrene sulfonate (PEDOT:PSS) as the hole injection layer (HIL), the OLED using PTT:PFFSA as a HIL gives enhanced efficiency and a slower luminance decay as well as a slower rise in operating voltage. Further studies of capacitance-voltage characteristics reveal that positive trapped charges accumulate in the hole transporting layer during operation."
According to the news reporters, the research concluded: "These results thus highlight the significance of hole injection layer to OLED operational stability."
