Fraunhofer ISE in collaboration with industrial partners have developed a fine-line metallisation process to create contact fingers with a width of 19µm and a height of 18µm in a single printing step that is almost invisible to the naked eye.
Wickon Hightech has developed a new model of the ‘SPEEDFilm’ inspection platform specifically for PV manufacturers. The ‘SPEEDFilm Solar’ system ensures 100% inspection of screen printed paste structures with a very high throughput that is able to handle thinner and thinner printed structures on c-Si solar wafers.
