Abstract (en)
[origin: WO2022263240A1] The invention relates to a method for producing at least one photovoltaic cell for converting electromagnetic radiation into electrical energy, comprising the method steps: A. providing a superstrate in the form of a semiconductor substrate; B. applying photovoltaic cell semiconductor layers directly or indirectly on a rear face of the superstrate to form at least one photovoltaic cell, wherein: the photovoltaic cell semiconductor layers comprise at least one absorber layer formed by a direct semiconductor; the superstrate is formed as a current-conducting layer and has a thickness of greater than 10 µm, and the photovoltaic cell semiconductor layers are designed to be electrically connected to the current-conducting layer in method step B; and the band gap of the current-conducting layer is greater than the band gap of the absorber layer by at least 50 meV.
