The invention belongs to a photocell electrode material and discloses a mixed electrode slurry for crystalline silicon solar cells. The mixed electrode slurry is prepared from, by weight, 40-60 parts of silver powder, 5-10 parts of zinc powder, 10-20 parts of silver coated nickel alloy powder, 1-5 parts of a lithium iron phosphate and carbon nanotube composite material, 1-8 parts of glass powder, 0.5-2 parts of a silane coupling agent, 10-15 parts of butyl carbitol acetate, 1-3 parts of zinc naphthenate, 0.1-0.5 part of hydroxymethyl cellulose and 0.25-1 part of hydrogenated castor oil. The invention further discloses a preparation method of the mixed electrode slurry. The mixed electrode slurry prepared by means of the preparation method does not contain lead, completely meets the requirements of environmental protection, is applied to the production of the solar cells and can form a strong attachment force on the surfaces of the solar cells, and the photoelectric conversion efficiency of the cells is high. In addition, the mixed electrode slurry is simple in process and low in cost and thus has a wide application prospect.
