ag powder is a high purity, spherical silver metal in the form of an inorganic, antibacterial powder. It is a safe and effective way to control infection and promote healing in deep wounds that do not respond to antibiotics. It can be used on pressure injuries, diabetic foot ulcers, partial- and full-thickness wounds, leg ulcers, negative pressure wound therapy, grafted wounds, donor sites and lacerations.

Antimicrobial properties: 6 log reduction of bacteria and >90% decrease in staphylococcus aureus, e. coli, and enterococcus faecalis within 48 hours. Suitable for hard-to-treat, deep wounds and nonstaining.

Solar Cell Metallization: Screen-printed Ag gridlines dominate the front-side metallization of c-Si solar cells because of their low cost, high throughput capability, and relatively environmentally benign manufacturing process. The typical front-side Ag paste contains Ag particles, glass frit and an organic vehicle that includes binder resins, solvents, rheological additives [1].

A conductive Ag-rich slurry is used to deposit Ag electrodes for the front-side of c-Si solar cells via screen-printing. The ag powder in the screen-printed paste is critical for line conductivity and solderability of the front-side grid to transfer the electrical power from the energy converting semiconductor bulk material to an external load. The optimally designed front-side metallization of c-Si based solar cells involves narrow gridlines that are less than 50 mm wide for mono- and poly c-Si solar cells. This is achieved by varying the surface topography of the ag powder, which improves thick-film viscoelastic recovery of the screen-printed Ag-rich slurry, mitigates dimensional variations and increases the aspect-ratio.
