Slimming down on silver

Using an innovative high-speed video setup, scientists in Germany were able to observe the screen-printing process used in solar cell metallization, on a time scale of less than 50 milliseconds. Insights into the paste's behavior and the mechanisms at work during screen printing will improve the process and the formulation of the silver paste it relies on.Solar cells use silver in the metallic 'fingers' screen printed onto their front sides, that transport charge generated in the silicon out into module and subsequently into the electricity system. Some experts predict that for solar to continue ...
