    摘要： This application discloses a perovskite-silicon-based laminated solar cell and a manufacturing method therefor, and relates to the field of laminated solar energy technologies, to obtain a perovskite-silicon-based laminated solar cell that has both a high open-circuit voltage and a high short-circuit current while retaining a textured structure of a bottom solar cell. The method for manufacturing a perovskite-silicon-based laminated solar cell includes: providing a substrate, where the substrate includes a silicon-based bottom solar cell having a textured structure, a charge composite layer, and a first carrier transport layer sequentially laminated; and forming, on the first carrier transport layer having the textured structure, a perovskite light absorption layer formed by a first perovskite layer and a second perovskite layer, where the first perovskite layer is prepared by using a solution method, and the second perovskite layer is prepared by using a perovskite skeleton vacuum evaporation method. The manufacturing method provided in this application is used to manufacture a laminated solar cell.

    摘要： The present application relates to a solar cell, a photovoltaic component and an electric apparatus. The solar cell comprises a plurality of sub-cells, wherein the plurality of sub-cells are successively arranged in a first direction, each of the plurality of sub-cells comprises a first photoelectric conversion layer for photoelectric conversion, and the first direction is perpendicular to a thickness direction of the sub-cells. In the first direction, the change trend of the thicknesses of the first photoelectric conversion layers of the sub-cells is negatively correlated with the change trend of the area of cross sections, which are perpendicular to a thickness direction of the first photoelectric conversion layers, of the first photoelectric conversion layers, such that the uniformity of photocurrents that are output by the sub-cells, and the uniformity of currents that are output thereby are improved. The solar cell in the embodiments of the present application can improve the efficiency of photoelectric conversion.
