During the self‐assembly process, the dynamic behavior of nanoparticles is correlated with the van der Waals force over both short (≈2–3 nm) and relatively long particle separations (<≈13 nm in this work). In article number 1901966, Jaehun Chun, Dongsheng Li, and co‐workers investigate how Ag nanoparticles self‐assemble into superlattices with short separations (<1 nm), which contribute to the...
Nanoparticle (NP) superlattices have attracted increasing attention due to their unique physicochemical properties. However, key questions persist regarding the correlation between short‐ and long‐range driving forces for nanoparticle assembly and resultant capability to predict the transient and final superlattice structure. Here the self‐assembly of Ag NPs in aqueous solutions is investigated by...
A simple process for nanotexturing on the emitter of silicon solar cells using catalyzed wet chemical etching by size-controlled silver nanoparticles was reported. A fine textured black surface was achieved to realize the low light reflectivity less than 5%. After screen printing and firing by the industrial standard fabrication protocol, we obtained the nanotextured Si solar cells with 15.7%-efficiency...
