Next, the influence of C60 on turn-on voltage will also be studied. Modifications to the C60 devices that can be integrated into simple fabrication processes, such as annealing or the addition of a PEDOT:PSS layer, will also be investigated for the improvement of C60 devices. It is concluded that the best condition for C60 devices in this study is to use an ITO/PEDOT:PSS/NPB(800Å)/Alq3(400Å)/C60(400Å)/LiF(10Å)/Al(1000Å) structure. |
