    Abstract: Known photovoltaic cells with wrap through connections have output terminals of both polarities on its back surface, one of which is coupled to the front surface via the wrap through connections. The invented solar cell is manufactured by creating an emitter layer on the back surface. Electrode material is applied in mutually separate first and second areas on the back surface. The electrode material in the first area contacts the emitter. The second area covers a surrounding of a hole that provides for the connection on the back surface. The electrode material in the second area lies on the emitter and around the second area the emitter is interrupted by a trench. On the front surface a further area of electrode material is applied over the hole. If necessary the electrode material in the second area on the back surface is applied on a supporting surface that is substantially electrically isolated from current flowing laterally through the emitter layer underneath the first area.
