A solar cell includes a semiconductor wafer, at least one dielectric layer arranged on the semiconductor wafer, a metal layer arranged on the dielectric layer, and a contact structure arranged in the dielectric layer such that the contact structure provides an electrical connection between the metal layer and the semiconductor wafer. The contact structure has at least one first structure having a minimum dimension and at least one second structure having a maximum dimension, wherein the minimum dimension and the maximum dimension are defined along a surface of the semiconductor wafer and the minimum dimension of the first structure is greater than the maximum dimension of the second structure.
