摘要
Charge carrier transport properties of hole-only devices based on poly(9,9-dioctylfluorene) (PFO) are investigated in terms of dark current-voltage (I-V) measurements. The built-in potential (V-bi) of the devices is determined by photovoltaic measurements. A power-law I-V relationship, I proportional to V-m (m>2), is found above the Ohmic region. Space-charge-limited current theory for exponential localized-state distributions can be applied to the interpretation of such behavior by taking account of Vbi.
