Perovskite-silicon-based laminated solar cell and manufacturing method therefor

A method for manufacturing a solar cell, comprising:

• providing a substrate, wherein the substrate comprises a silicon-based bottom solar cell, a charge recombination layer, and a first carrier transport layer that are sequentially laminated, wherein the first carrier transport layer has a textured structure;
• and
• forming, on the first carrier transport layer, a perovskite light absorption layer comprising:
• forming a first perovskite layer of the perovskite light absorption layer on the first carrier transport layer based on a solution method performed with a perovskite solution comprising a solute that is a hybrid perovskite component CsxFAyMAzPbBrmIn (x+y+z=1 and m+n=3);
• and
• after forming the first perovskite layer, forming a second perovskite layer of the perovskite light absorption layer based on a perovskite skeleton vacuum evaporation method,
• wherein an average thickness of the first perovskite layer is less than or equal to half a height of the textured structure.
