Plasmon enhanced performance of fullerene based small molecule organic solar cell with Au nanoparticles

In the present work, we describe the fabrication of fullerene (C70) based small molecule organic solar cell (OSC) devices with and without metallic gold nanoparticles (AuNPs) using thermal vapor deposition technique. AuNPs are prepared using seed-mediated method and incorporated in the anode buffer poly-(3,4- ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) layer of OSC device with electron donor-acceptor pairing of 4,4′-Cyclohexylidenebis[N,N-bis(4-methylphenyl)benzenamine] (TAPC)/C70 active bilayer. Current – voltage characteristics of both plasmonic device (with AuNPs) and reference device (without AuNPs) is analyzed to examine plasmonic effects of metallic AuNPs. We report the significant enhancement in power conversion efficiency (PCE) of plasmonic device as compared to reference device. The enhancement in PCE of OSC with structure FTO/PEDOT:PSS/TAPC/C70/Al is originated by surface plasmon and enhanced scattering effects of AuNPs.In the present work, we describe the fabrication of fullerene (C70) based small molecule organic solar cell (OSC) devices with and without metallic gold nanoparticles (AuNPs) using thermal vapor deposition technique.
