The invention provides a solar cell slurry recycling method. A screen, a printer head, contaminated silver slurry on a scraping bar, silver dry slurry and other small solid particles are collected, are added with an organic solvent, and are mixed for 3 to 6 hours. The improved slurry is used for back electrode printing. The process is helpful to recycle and reusing all types of silver slurry. Back silver consumption is reduced. The production cost of a cell is reduced. The benefit of an enterprise can be improved. The cost is reduced.
