Abstract
High-efficiency surface plasmon enhanced
1,1-bis-(4-bis(4-methyl-phenyl)-amino-phenyl)-cyclohexane:C70
small molecular bulk heterojunction organic solar cells with a MoO<sub>3</sub> anode buffer layer have been demonstrated. The optimized
device based on thermal evaporated Ag nanoparticles (NPs) shows a
power conversion efficiency of 5.42%, which is 17% higher than the
reference device. The improvement is attributed to both the enhanced
conductivity and increased absorption due to the near-field enhancement
of the localized surface plasmon resonance of Ag NPs
