The solar cell is disposed on an insulating layer between the fingers of the contact on the reverse side. The solar cell has a field electrode supplied by an external voltage source. The electrode, which is at a negative potential and generates an E-field at the semiconductor/insulator boundary. The semiconductor includes a single or multi-layer anti-reflection layer. This electrode is made of an electrically conductive, transparent material. The electrons in the boundary region are driven in the direction of the pn-transition layer while the holes are accelerated towards the contact on the reverse side. The ohmic contacts are finger or gate-shaped and are disposed on an insulation layer.
