Silver nanoparticle plasmonic effects on hole-transport material-free mesoporous heterojunction perovskite solar cells

Compact TiO2 films with sandwiched Ag nanoparticles as electron-collecting layer in planar type perovskite solar cells: improvement in efficiency and stability

“…S2a, ESI †) revealed the absorption edge for pristine c-TiO 2 shied from 387 nm for the single layer c-TiO 2 toward around 413 nm for the Ag NPsembedded c-TiO 2 layers, presumably due to the incorporation of Ag NPs, which is known to give UV absorption above 400 nm. 37,[44][45][46] Importantly, the TiO 2 ETL embedding Ag NPs showed stronger UV-Vis absorption compared to the pristine c-TiO 2 , which may be the result of Surface Plasmon Resonance (SPR) of Ag NPs. All the aforementioned characterizations conrmed that Ag NPs were successfully formed in between the c-TiO 2 layers.…”

“…32 In particular, silver nanoparticles, Ag NPs, were incorporated in various ways in different layers of perovskite solar cells (PSCs) and beneciary effects have been demonstrated. [33][34][35][36][37][38][39] Nevertheless, these devices usually involved more complicated preparation procedures, with little elaboration of the detailed mechanism.…”

High performance of mixed halide perovskite solar cells: Role of halogen atom and plasmonic nanoparticles on the ideal current density of cell

“…In majority of experimental and theoretical papers, Ag and Au are known as a cost-efficient material with considerable plasmonic effects [38,39] while Platinum nanoparticles exhibit localized surface plasmons with a higher sensitivity as well [40][41][42].…”

Applications of Silver Nanoparticles: A Review

“…The incor-poration of silver nano particles (coupled with InAs/GaAs) have been reported for enhancing the overall power conversion efficiency enhancement and the spectral response of solar cells due to efficient light scattering and trapping by surface plasmon generated in broad band absorption enhancement 55 . Nourolahi et al 56 utilized the optimal concentration of silver nano particles to the TiO 2 based solar cells which improved the power conversion efficiency of fabricated cell. It is reported that the incorporation of silver nano particles effectively, extended the optical pathway of incident light which increased the photo absorption of photo active layer.…”
