Abstract

Incorporating appropriate plasmonic nanostructures into photovoltaic (PV) systems is of great utility for enhancing photon absorption and thus improving device performance. Herein, the successful integration of plasmonic gold nanostars (AuNSs) into mesoporous TiO₂ photoelectrodes for perovskite solar cells (PSCs) is reported. The PSCs fabricated with TiO₂ -AuNSs photoelectrodes exhibited a device efficiency of up to 17.72 %, whereas the control cells without AuNSs showed a maximum efficiency of 15.19 %. We attribute the origin of increased device performance to enhanced light absorption and suppressed charge recombination.

Keywords: gold nanostructures; perovskite solar cells; photoelectrodes; photovoltaics; plasmonic effect.
