Abstract
The present disclosure relates to a silicon/perovskite tandem solar cell and a preparation method thereof and belongs to the technical field of perovskite tandem cells. The silicon/perovskite tandem solar cell includes a silicon bottom cell and a perovskite top cell, in which a seed crystal silicon layer and a tunneling layer are sequentially arranged between a surface of the silicon bottom cell and a bottom surface of the perovskite top cell, the seed crystal silicon layer being adjacent to the silicon bottom cell, and the tunneling layer being adjacent to the perovskite top cell. Here, the seed crystal silicon layer is an amorphous silicon layer, and the tunneling layer is a doped microcrystalline silicon oxide layer. The cell facilitates the tunneling between the silicon bottom cell and the perovskite top cell, thereby improving the open circuit voltage and the conversion efficiency of the cell.
