Abstract
The invention relates to the technical field of solar cells, in particular to a three-dimensional framework silicon/perovskite tandem solar cell and its preparation method. The three-dimensional framework silicon/perovskite tandem solar cell comprises a formal structure or a trans structure; a p-type amorphous silicon layer, a top electrode light-transmitting layer, an n-type transmission layer, a perovskite thin film, a p-type transmission layer, a buffer layer and a transparent electrode which are sequentially laminated on a substrate from bottom to top; when it is in a trans structure, it comprises a p-type silicon nanowire, an i-type intrinsic amorphous silicon layer, an n-type amorphous silicon layer, a top electrode light-transmitting layer, a p-type transmission layer, a perovskite thin film. The present invention can improve the absorption efficiency of the cell for incident light, broaden the absorption spectrum, and further improve the photoelectric conversion efficiency of the solar cell.
