Solar cell with a protection diode and its manufacturing method

摘要

The solar cell has an integral protective diode of opposite polarity to the solar cell and which has at least one diode semiconductor layer. The solar cell has at least one back contact, a substrate for carrying photoactive layers of different polarities, and a front contact. The protective diode (28) is integrated in the solar cell and is arranged on its front side. The diode semiconductor layer is formed at least in parts from the solar cell. Independent claims also cover a method of manufacturing such a solar cell.
