Description

technical field [0001] The invention belongs to the field of solar cells, and in particular relates to a method for preparing a cross-linked fullerene heterojunction perovskite solar cell. Background technique [0002] Bulk heterojunction solar cells are favored by many researchers for their high-efficiency electron-hole transport properties. This bulk heterojunction device structure is widely used in organic solar cells and fuel-sensitized cells. However, in perovskite solar cells The planar heterojunction device structure is usually used in the battery, which limits the photocurrent transmission of the battery device to a certain extent, and restricts the further improvement of the energy conversion efficiency of the battery device. [0003] In addition, the short carrier migration length restricts the improvement of the efficiency of planar heterojunction perovskite solar cells to a certain extent, and the current short-circuit current density is usually 18-20mA / cm 2 Man...
