Plasmonic-enhanced polymer solar cells with high efficiency by addition of silver nanoparticles of different sizes in different layers

This article described a dual plasmonic effect on improving the performance of polymer solar cells (PSCs). The silver nanoparticles (AgNPs) of different sizes are blended respectively into the double anode buffer layers and the active layer to trigger localized surface plasmon resonance (LSPR), which enhanced the broadband absorption of the PSCs. The power conversion efficiency of the PSC device incorporating the AgNPs is runned up to 9.2%, accounting for a 21.7% enhancement as compared to pre-optimized control PSCs.100
