Abstract
A method for manufacturing high-efficiency solar cells from polycrystalline or monocrystalline semiconductor material is disclosed. Backside contacts are printed on with a metal-containing paste and front side contacts are deposited finely-structured photo-induced. To that end, a nickel layer is deposited photo-induced directly on the semiconductor that is uncovered in openings or trenches within a passivation layer on the front side. The front side contact is reinforced by a further metal layer that is likewise produced by currentless deposition.
