The front side (10) is provided with a first pattern (13) of conductive elements (51, 52) which are connected to first contact points (15) on the rear side (20) by means of a number of vias (14) in the solar cell. The rear side (20) is provided with a second pattern of conductive elements (22) which are connected to second contact points (21) on the rear side (20). The first and second contact points (15, 21) are situated along a number of lines (30). The first contact points (15) are situated on a first side of the lines (30) and the second contact points (21) are situated on a second side of the lines (30).

摘要:
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.

A solar panel module includes a transparent carrier and semi-conductor substrate portions that have a front surface and a rear surface. The front surface is arranged for capturing radiation energy. The semiconductor substrate portions are arranged adjacent to each other on the transparent carrier and are separated from each other by a groove. Each semiconductor substrate portion is attached with the front surface to the transparent carrier. Each groove includes a side wall of each of the adjacent semiconductor substrate portions. The front surface of each semiconductor substrate portion is provided with a doped layer of a first conductivity type. Each semiconductor substrate portion includes a first electric contact for minority charge carriers and a second electric contact for majority charge carriers in the semiconductor substrate portion. The first electric contact is arranged on at least the rear surface of the semiconductor substrate portion as a heterostructure of a first type. The hetero junction of the first type includes an intrinsic semiconductor layer on the semiconductor substrate portion and a semiconductor layer of a second conductivity type, opposite to the first conductivity type, on top of the intrinsic semiconductor layer.
