The invention relates to a method for recycling waste perovskite solar cells. The method comprises the following steps: (1) perovskite solar cells are immersed into solvent capable of dissolving perovskite material except other components and washed; (2) the solid and liquid of cleaning solution obtained in step (1) are separated, so that lead-containing extract is obtained; (3) the obtained lead-containing extract reacts with ammonia water, so that first turbid liquid is obtained; (4) the solid and liquid separation is performed on the obtained turbid liquid, so that first solid is obtained;(5) the first solid reacts with acetic acid, so that second turbid liquid is obtained; (6) the solid and liquid separation is performed on the second turbid liquid, so that Pb(CH3COO)2 solid is obtained.
