NOVELTY - Slurry layers (A,B) are formed sequentially by filling lower nozzle with slurry (A) and upper nozzle with slurry (B), nozzles being connected with a container, setting the nozzles in parallel, and spraying from the lower nozzle at 0.5 MPa and upper nozzle at 0.65 MPa, setting the traveling speed of lower and upper nozzles to 125 mm/second. The slurries are dried at 140-160 degrees C, to obtain a front gate line electrode. Slurry (A) comprises (in parts weight) organic carrier (23), silver powder (70), glass powder (5), and ohmic contact additives (2).    USE - Preparation of front gate line electrode for solar cells.    ADVANTAGE - The method enables preparation of front gate line electrodes with high aspect ratio, and excellent positional accuracy and conductivity. Fragmentation of silicon chip by application of pressure is prevented.    DETAILED DESCRIPTION - Slurry layers (A,B) are formed sequentially by filling lower nozzle with slurry (A) and upper nozzle with slurry (B), nozzles being connected with a container, setting the nozzles in parallel, and spraying from the lower nozzle at 0.5 MPa and upper nozzle at 0.65 MPa, setting the traveling speed of lower and upper nozzles to 125 mm/second. The slurries are dried at 140-160 degrees C for 14-16 minutes, to obtain a front gate line electrode. Slurry (A) comprises (in parts weight) organic carrier (23), silver powder (70), glass powder (5), and ohmic contact additives (2). The organic carrier comprising terpineol, butyl carbitol, ethyl cellulose, and the remaining components in a weight ratio of 55:30:10:5 are heated to 60 degrees C and stirred for 2 hours or more to obtain slurry (A). Slurry (B) comprises organic carrier (10), silver powder (85), glass powder (1), and metal phase binder (4). The organic carrier comprising terpineol, butyl carbitol, ethyl cellulose, and the remaining components in a weight ratio of 53:28:14:5 are heated to 60 degrees C for 2 hours or more to obtain slurry (B). The particle size of silver powder is 0.01-10 mu m. The glass powder is boron-silicon-lead group glass, bismuth-silicon-antimony group glass, bismuth-silicon-zinc group glass, or bismuth-silicon-lead group glass.
