WebbPassivation of the silver nanowires in solution before mixing with PEDOT:PSS was attempted using two small molecules, MuA and MBI. However, the performance of electochromic devices using these passivated nanowires was poor due to nanowire clumping. Alternative suggestions for passivating silver nanowire surfaces in solution … WebbA slow surface passivation was observed; the performance of the PHSCN device improved upon increasing the storage period to attain an efficiency of 13.5% for a current−voltage scan in the forward bias direction. An inverted effect of hysteresis was observed in that the efficiency of the forward scan was greater than that of the reverse scan.
