  • Publication number: 20240282872
    Abstract: A method for producing at least one photovoltaic cell for converting electromagnetic radiation into electrical energy, having the method steps of: A. providing a superstrate in the form of a semiconductor substrate; B. applying photovoltaic cell semiconductor layers for forming at least one photovoltaic cell to a rear face of the superstrate indirectly or directly, and the photovoltaic cell semiconductor layers have at least one absorber layer formed from a direct semiconductor. The superstrate is in the form of a current conducting layer having a thickness greater than 10 ?m and, in method step B, the photovoltaic cell semiconductor layers are formed with an electrically conductive connection to the current conducting layer and wherein the band gap of the current conducting layer is larger by at least 50 meV than the band gap of the absorber layer.
