“…After stabilization by PVP molecules, the Au NPs with a typical diameter of 14 nm were added to a mixture of ammonia and ethanol. In the second stage, the silica precursor tetraethyl orthosilicate (TEOS) was added dropwise to the mixture and a silica shell *13 nm thick was formed by an improved Stober process [25]. These Au-silica NPs have one LSPR absorption peak at 528 nm which is red shifted with respect to that of Au NPs because of the silica shell [25].…”

“…It is useful to review the field of plasmonic OPV in this way because there is at present no consensus on the relative merits of each approach. Some investigators argue that incorporating core shell metallic NPs may adversely affect the charge transport within the BHJ [25]. On the other hand, adding NP with organic ligands into the BHJ has been reported to cause exciton quenching or carrier recombination [16].…”

The effect of noble metal nanoparticle (NP) synthesis method on the plasmonic enhancement of organic photovoltaic device performance by these NPs is reviewed. For direct incorporation into a polymer fullerene bulk heterojunction (BHJ) active layer, chemically synthesized colloidal Au or Ag NPs with organic ligands are generally ineffective. Due to the tendency of the ligands in causing exciton quenching, carrier trapping and recombination, the device power conversion efficiency (PCE) can be lower than a BHJ device without NPs. Ligand-free metal NPs prepared by physical methods such as pulsed laser ablation and electron beam evaporation can enhance the PCE when introduced into the BHJ. An alternative effective approach for both polymer and small molecule BHJ devices is core shell metal-silica NPs. Regardless of synthesis method, the NP size should be controlled to the range of *50-100 nm to increase light trapping due to scattering and achieve synergistic enhancement. A non-spherical NP morphology with tunable dual localized surface plasmon resonance peaks at visible wavelengths is highly desirable. For core shell metal-silica NPs, the dielectric shell thickness must be optimized to ensure significant localized field enhancement at the surface of the NP.

Solution processed thin‐film solar technologies, such as organic photovoltaics, and more recently, perovskite solar cells, may provide low‐cost electricity generation. These technologies suffer from insufficient light absorption due to thin absorber layers. Plasmonic nanostructures have been incorporated in both technologies, initially with the aim of increasing light absorption, but reports have also shown significant enhancement in electrical characteristics in devices. Enhancement mechanisms that are facilitated by plasmonic nanostructures such as improved exciton dissociation and charge carrier transport, can occur concurrently with improved light absorption. This work surveys the myriad enhancement mechanisms and, importantly, discusses the extent of current understanding, as well as insights gained in plasmonics applications thus far. Given the substantial opportunities, the continuous focus on characterization and interpretation of enhancement mechanisms is imperative to unlock the full potential of plasmonic organic and perovskite solar cells. In particular, electrical or electronic effects from plasmonic nanostructure integration deserves further attention as a promising complement to improvements in device performance from optical effects.
