“…The Au‐NPs are assumed to cause a sub‐millisecond recombining process, which increases the possibility of recombination in the PVSCs. Recent reports described high concentration noble metal nanoparticles embedded inside PVSCs causing efficiency decrease, and this is in agreement with our observation …”

NiOx is a promising hole transport material for p‐i‐n perovskite solar cells (PVSCs) on account of its high mobility, excellent stability and prospect for large‐scale fabrication. However, the typical conductivity of NiOx is low because of the low carrier concentration, which consequently compromises its photovoltaic performance. Herein, we show that the carrier concentration of NiOx can be improved by as much as three times through embedding a small concentration (0.11 At%) of gold nanoparticles (Au‐NPs), 2–3 nm in diameter, into the NiOx thin film. The enhancement is due to the formation of Ohmic contact between Au and NiOx while avoiding direct contact between Au and perovskite. All key parameters of the PVSC, namely Jsc, Voc, and FF have improved, and the overall efficiency shows a significant improvement from 17.8% to 20.2%. The small size, low concentration, and Ohmic contact nature of the embedded Au‐NPs, together with this simple method point to a new promising direction for developing high performance PVSCs.

“…[199][200][201][202][203][204][205][206][207][208][209][210] Plasmonic enhancement is achieved mainly through three mechanisms, including far-field scattering, near-field enhancement, and charge carrier or resonant energy transfer. [206] Subwavelength-sized nanoparticles of noble metals such as Au and Ag can exhibit strong localized surface plasmon resonances (LSPRs) at the wavelengths range from UV, visible to near infrared (NIR), depending on the kind of material, their size, particle aspect ratio, and the environment.…”

Clean and sustainable hydrogen generation renders a magnificent prospect to fulfill the humans' dream of rebuilding energy supplying systems that work eternally and run without pollution. Water electrolysis driven by a renewable resource of energy, such as wind and solar, is a promising pathway to achieve this goal, which requires highly active and cost‐effective electrode materials to be developed. In this comprehensive review, we introduce the utilization of hierarchical nanostructures in electrocatalytic and photoelectrochemical applications. The unique emphasis is given on the synthetic strategies of attaining these hierarchical structures as well as to demonstrate their corresponding mechanisms for performance improvement. Rather than simply discussing all the methods that can be used in nanofabrication, we focus on extracting the rules for structural design based on highly accessible and reliable methods. Examples are given to illustrate the versatility of these methods in the synthesis and manipulation of hierarchical nanostructures, which are concentrated on nonprecious transition metals or their alloys/compounds. Through this study, we aim to establish valuable guidelines and provide further insights for researchers to facilitate their design of more efficient water splitting systems in the future.

Inorganic hole‐transporting materials (HTMs) profoundly improve the stability and robustness of the solar cell compared to that expected from organic HTMs. In this work, the efficiency of a perovskite solar cell is greatly enhanced using a hexagonal nanoprism array of inorganic metal oxide HTM. We found that the introduced structure increases the efficiency of the mesoscopic configuration by 42% higher than that of the planar perovskite solar cell with the same thickness of the active layers. The reason of this enhancement in power conversion efficiency is the better carrier transportation in the mesoscopic configuration. The periodic array of mesoscopic hole‐transporting layer is vastly tunable and reveals unique capabilities of designing a particular array, which can enhance the efficiency of the perovskite solar cell. We also incorporated plasmonic nanoparticles into the absorber layer and found that they significantly could improve the performance of the solar cell. The inclusion of spherical nanoparticles improves the light absorption of the bare mesoscopic solar cell. An increasing number of nanoparticles enhances the light trapping inside the active layer and as a result improves the probability of light absorption.
