The invention provides a method for manufacturing a back passivation point contact solar cell of an aluminum slurry burning-through local thin film. The method comprises the steps of damage removing of a silicon wafer, woolen manufacturing, cleaning, phosphorus diffusion, back phosphorosilicate glass removing, back polishing, phosphorosilicate glass removing and cleaning, back aluminum oxide / silicon nitride laminated thin film growing, front silicon nitride antireflection thin film growing, reverse printing of burning-through aluminum paste, drying, reverse printing of a back electrode and an aluminum layer, front printing of a silver grid line, sintering and testing. burning-through type aluminum paste can be adopted by back point contact of the cell, meanwhile, thin film perforating is achieved, aluminum silicon contact is achieved, a local aluminum back field is formed at the contact position, and therefore two processing steps (laser perforating of the thin film, and aluminum paste sintering and silicon contact) are reduced into one step (adopting of aluminum paste of the burning-through thin film, and needing no thin film perforating in advance), investment of laser equipment is saved, idle printing equipment is fully utilized, and the method has the practical significance.
