(54) TANDEM SOLAR CELL AND METHOD OF MANUFACTURING THE SAME


(57) The present disclosure provides a method of manufacturing a tandem solar cell (1) comprising a stack of at least a rear photovoltaic component (1R) and a front photovoltaic component (1F) between a front electrode (215) facing a light entry window (211) and a rear electrode (225). The tandem solar cell (1) to be manufactured therewith is configured to perform a photovoltaic conversion of light received through the light entry window (211) to provide an output voltage between the electrodes. The front photovoltaic component (1F) is configured to convert a first portion of the received light and the rear photovoltaic component (1R) is configured to convert a second portion of the received light that is transmitted by the front photovoltaic component (1F). The stack includes a substrate (23) with a first side (231) facing the light entry window (211) and a second side (232) facing away from the light entry window (211). The method comprises providing (S1) the substrate (23), depositing (S3R, S3B, S3F) functional layers on the substrate (23). In particular the method comprises one or more bilateral deposition steps (S3B) wherein a substance is simultaneously deposited at both sides of the substrate.
