N2 - Surface plasma resonance (SPR) effect has been demonstrated to improve solar cell performance.This work reports on the SPR effect from Au nanorod@SiO2on p-type dye-sensitized solar cells. Aunanorod@SiO2works as an antenna to transform photons with long wavelength into electric field fol-lowed by an enhanced excitation of dye. The devices using the NiO electrode containing Au nanorod@SiO2shows overall power conversion efficiencies of about 0.2% in combination with I−/I3−electrolyte, and0.29% with T−/T2electrolyte, which are superior to those without adding Au nanorods. Detailed inves-tigation including spectroscopy and transient photovoltage decay measurements reveals that plasmaeffect of Au nanorod@SiO2contribute to charge injection efficiency, and thus on the photocurrent. Theeffect of Au NRs can be further extended to the inverted planar perovskite solar cells, showing obviouslyimprovement in photocurrent.
