The invention relates to a perovskite/crystalline silicon stacked solar cell structure, comprising: a bottom cell and a perovskite top cell; the bottom cell is a crystalline silicon-PERC bottom cell or a crystalline silicon-PERT bottom cell; The perovskite top cell includes a perovskite cell carrier transport layer A, a perovskite absorption layer, a perovskite cell carrier transport layer B, a transparent conductive film and a top electrode grid line; the top electrode grid line on top of the transparent conductive film. The beneficial effects of the present invention are: this perovskite/crystalline silicon-PREC or perovskite/crystalline silicon-PERT can utilize the current production line of crystalline silicon PREC or PERT solar cells, and only needs to make a small amount of improvement. A good bottom cell can be prepared, the efficiency of solar cells can be improved, and the production cost of perovskite/crystalline silicon tandem cells can be reduced; this structure can form a reliable full-surface tunnel junction contact without rectification effect; the preparation process is fully compatible with existing silicon The battery production method can be uniformly prepared on the whole surface, the process is simple, and the reliability is strong. |
