The invention relates to the technical field of solar cells, in particular to a perovskite/crystalline silicon laminated cell assembly and a preparation method thereof. The perovskite/crystalline silicon laminated battery assembly includes: a crystalline silicon battery group and a first perovskite battery group arranged in layers, the crystalline silicon battery group includes at least one crystalline silicon battery, and the first perovskite battery group includes at least one first perovskite battery group. A perovskite cell; the surface of the crystalline silicon cell facing the first perovskite cell group has a first grid line, the first grid line includes a plurality of first sub-grids, the first perovskite cell has a cutting line, and the cutting line The orthographic projection on the surface of the crystalline silicon cell is located in part of the first sub-grid. The hot spot effect of the perovskite/crystalline silicon stacked battery module is weakened, thereby slowing down the decay speed of the crystalline silicon battery caused by the hot spot effect, and improving the photoelectric performance of the perovskite/crystalline silicon stacked battery module. stability. |
