SOLAR CELL

摘要

Solar cell including a semiconductor substrate with a first and second side, a first contact structure disposed in the region of the first side of the semiconductor substrate and contacting the semiconductor substrate, a passivation layer with openings disposed on the second side of the semiconductor substrate, and a second contact structure disposed on the passivation layer, which locally contacts the semiconductor substrate through the openings of the passivation layer, wherein the first contact structure has a strip-shaped connection element and contact fingers connected to the connection element, and wherein the passivation layer has an openings-free region extending along the connection element in a region under the strip-shaped connection element of the first contact structure.
