在C60掺杂的聚（3-烷基噻吩）（PAT）中观察到了持续光电导（PPC）。PPC随着辐照时间的增加而增加，趋于饱和。PPC也随C60浓度的增加而增加，并趋于饱和，高浓度时甚至下降。新的PPC的温度依赖性已被观察到。这种PPC已被讨论在C60掺杂的PAT中的增强的光激发载流子密度和抑制的初级负和正载流子的复合，由于在C60和PAT中的缺陷态的陷阱电子的稳定。
Persistent photoconductivity (PPC) has been observed in C60-doped poly(3-alkylthiophene) (PAT). PPC increases with increasing irradiation time, tending toward saturation. PPC also increases with C60 concentration, tending toward saturation or even decrease at high concentration. Novel temperature dependence of PPC has been observed. This PPC has been discussed in terms of enhanced photoexcited carrier density in C60 doped PAT and the suppression of the recombination of primary negative and positive carriers due to the stabilization of trapped electrons in C60 and defect states in PAT.
