Latest Patents

One of his latest patents is titled "Method for producing a rear-side contact system for a silicon thin-layer solar cell." This method involves applying an organic insulation layer to the emitter layer of a silicon thin-film solar cell. It includes producing contact holes in the insulation layer, insulating these holes, and applying a low-melting metal layer to form n and p contacts. The process also involves laser-cutting to separate the metal layer into n-contacting and p-contacting regions. Additionally, a TCO layer is applied before the organic insulation layer, and holes for contacts are produced in the insulation, followed by selective doping.

Another significant patent by Gall is the "Single-sided contact solar cell with plated-through holes and method for its production." This invention features a solar cell with an absorber layer that includes plated-through holes and an emitter layer on one side. The design incorporates a field passivation layer on the opposite side and a contact grid that is insulated from the contact layer. This innovative structure allows for efficient electrical connections while maintaining insulation between components.
