Surface Plasmon Enhanced Organic Solar Cells with a MoO3 Buffer Layer

摘要

High-efficiency surface plasmon enhanced 1,l-bis-(4-bis(4-methyl-phenyl)-amino-phenyl)-cyclohexane:C70 small molecular bulk heterojunction organic solar cells with a MoO3 anode buffer layer have been demonstrated, The optimized device based on thermal evaporated Ag nanoparticles (NPs) shows a power conversion efficiency of S.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.
