NOVELTY - Crystal silicon solar battery electrode slurry, comprises (in wt.%): 559 gamma metal silver powder (69.99), glass adhesive (1-6), organic resin (3-6), organic solvent (20-30), 0.19 gamma rheology auxiliary agent (0.1-0.5), and metal silicide (0.1-5), where the metal silicide contains 1-6 wt.% of the silicon obtained by performing annealing at 30-90 degrees C, and crushing the metal silicide using crushing ball mill to prepare metal silicide powder, and the metal is chosen from platinum, palladium, titanium, nickel, aluminum, manganese, cobalt, and silver.    USE - The electrode slurry is useful for crystalline silicon solar battery.    ADVANTAGE - The slurry enhances contact between metal electrode and silicon, has low resistivity and strong bonding force, does not impair battery condition, reduces silver content, consumes less energy, and is cost-effective, contains bonding agent without lead hence it causes no polution to the environment, and improves performance of battery.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method of preparing above-mentioned slurry, which involves (a) preparing metal component of the metal silicide, metal powder and silicon powder in the resistance furnace at 30-90 degrees C, preserving heat for 2 hours, annealing the metal component, and preparing metal component into metal silicide powder having grain diameter of 5 microns in organic solvent, (b) preparing a gene delivery carrier, heating the reaction kettle at 7-10 degrees C, preparing organic solvent, organic resin, and rheology auxiliary agent until the carrier is dissolved completely in the reaction kettle at constant temperature, stirring the materials, cooling the stirred materials, and preparing cooled material into paste, and (c) mixing electrode slurry, metal silver powder, organic carrier, glass adhesive and metal silicide by high speed dispersion stirrer to stir evenly, grinding the mixture using three-roller grinder to obtain slurry having fineness of 4-8 microns, and viscosity of 5-l00 Pa at 25 degrees C.
