Jörg Horzel and his team developed a process that streamlined the production of silicon-based solar cells, which were long too expensive for commercially viable production.
In order for solar cells to conduct electricity, their silicon base must be coated with phosphorous on one side, which involved applying a phosphorous paste to the entire front side of the cell. This caused some of the paste to end up on the rear side, and removing it was an expensive and time-consuming process. Horzel found a way to apply the paste to only certain sections of the cell surface, eliminating the step of removing it from the rear side. The result was a more efficient and cost-effective path to solar energy.
