Surface plasmon assisted high performance top-illuminated polymer solar cells with nanostructured Ag rear electrodes

Abstract

Highly efficient plasmonic Ag rear electrodes in top-illuminated PSCs employing MoO₃/Ag (13 nm)/MoO₃ stacks as top transparent electrodes were successfully demonstrated, resulting in the significant enhancement of solar cell performance with a PCE of up to 7.18%. The hemispherical Ag nanostructured arrays effectively concentrate incident light within the photoactive layer in addition to contributing to extended stability with a robust structure.
