Performances of Au NP Devices

Four device structures have been investigated [56] as follows: Device A: (control): ITO/PEDOT:PSS/P3HT:PCBM/LiF (1 nm)/Al (100 nm) Device B: ITO/PEDOT:PSS? Au NPs/P3HT:PCBM/LiF (1 nm)/Al (100 nm) Device C: ITO/PEDOT:PSS/P3HT:PCBM? Au NPs/LiF (1 nm)/Al (100 nm) Device D: ITO/PEDOT:PSS? AuNPs/P3HT:PCBM? Au NPs/LiF (1 nm)/Al (100 nm) J-V characteristics of the four OSC device structures with Au […]

Section Summary

The effects of Au NPs incorporated into the active layer PFSDCN:PCBM of OSCs have been described in this section. Theoretical simulations indicated that the near field of NPs distribute laterally along the active layer, leading to the absorption improvement which is also experimentally observed. On the other hand, electrical properties of these OSCs are also […]

Voc

As Au NPs concentration increases, VOC first increases from * 0.90 (without Au NPs) to *1.01 V (Au NPs: 0.5 wt%) and then decreases. When Au NPs con­centration increases to 6 wt%, VOC reduces significantly to 0.44 V. In BHJ OSCs, charge recombination is commonly regarded as one important loss mechanism limiting VOC. [49, 50]. […]
