Summary: Researchers have developed an organic solar cell-based retinal prosthesis embedded with spherical gold nanoparticles to enhance the efficiency of the bioelectric interface. Computational modeling showed that this nanoparticle-enhanced solar cell had three times higher efficiency compared to a bare solar cell. By incorporating gold nanoparticles, the prosthesis can be miniaturized and requires lower light intensity for neural activation.

Summary: Silver doped nickel oxide nanocomposites were synthesized for thin-film organic solar cell applications, resulting in two distinct colors of green and black powders. An optimum concentration of 1 wt% of Ag:NiOx powders yielded the highest power conversion efficiency, while higher concentrations were unfavorable for improving device performance. The synthesized metal NCs significantly improved device performance compared to reference cells.

Summary: A sensitive and selective sensor for the detection of arsenic (iii) in polluted water samples has been developed using chitosan-stabilized silver nanoparticles (AgNPs). The synthesized silver nanoparticles have a size of 6 nm and a polydispersity index (PDI) of 0.3, enhancing the electroactive surface area and sensor sensitivity. The sensor shows high selectivity even in the presence of other possible interferents. The detection of As(iii) was performed using differential pulse anodic stripping voltammetry (DPASV), with a detection limit of 11.39 pM.

Summary: The research focused on developing alternative counter electrodes for dye-sensitized solar cells (DSSC) using simple methods. The NiCo2S4 counter electrode showed comparable photovoltaic performance to the platinum-based counter electrode, potentially due to its high electrocatalytic activity and small nanoparticle size providing increased surface area and catalytic sites. A theoretical model based on electrical considerations was used to study the impact of physical parameters on DSSC performance and efficiency, with the model accurately reproducing DSSC characteristics.

Summary: A silver nanowire-based stacked lamination electrode was investigated for organic photovoltaic fabrication without vacuum or solution processing. The electrode showed lower fill factor and photoconversion efficiency compared to OPVs with a reference evaporated metal electrode. Analysis indicates that higher series resistance and recombination at the interface contribute to the performance differences.

Summary: By electrochemically synthesizing silver wire within a nanopipette using a liquid-liquid interface, the i-t curve characterizes the growth state of the silver wire, with a higher rate of current increase indicating faster growth. The shape of the nanopipette also influences the growth of the silver wire, with larger diameters leading to multibranched structures and smaller diameters resulting in fewer branches.
