Thick film and screen printing technology are challenged with providing materials that achieve high aspect ratios. The solutions must provide viable options for high volume solar cell production, as this is where the advantage is gained over competing technologies. Thick film paste must maintain good printability throughout the time on the screen, and the screen parameters must allow for high throughput and repeatability of results. Time required for slow printing speeds, changing clogged or broken screens, replacing worn squeegees, or removing damaged wafers are costly procedures for solar cell manufacturers.
