NOVELTY - A continuous through-type silicon solar battery diffusion method comprises: placing carrying sheet for quartz boat (4) loading blade (1) from left end of diffusion furnace (2), blade (5) from right end of diffusion furnace, stopping load of blade when reaching constant temperature area (3); and passing loading blade through lifting mechanism, loading blade from diffusion furnace, slowly withdrawing the blade from constant temperature area, ensuring each silicon wafer has same diffusion environment and same speed through constant temperature area.    USE - Continuous through-type silicon solar battery diffusion method.    ADVANTAGE - The variance of resistance of each silicon wafer is reduced for improving solar cell performance.    DETAILED DESCRIPTION - A continuous through-type silicon solar battery diffusion method comprises: (A) placing a carrying sheet for quartz boat (4) loading blade (1) with speed of 150-300 mm/minute from left end of diffusion furnace (2), the blade (5) at speed of 150-300 mm/minute from right end of diffusion furnace, stopping the load of blade when reaching the constant temperature area (3), entering loading blade front end piece to constant temperature area, continuously advancing loading blade at a speed of 25-75 mm/minute, stopping when loading blade of quartz boat is located in diffusion furnace central area of constant temperature area; and (B) passing loading blade through lifting mechanism, reducing speed to 10-30 mm/minute, setting quartz boat to the loading blade with load to blade, loading blade from diffusion furnace at the speed of 300-800 mm/minute up to the original position at speed of 20-50 mm/minute re-loading silicon wafer, slowly withdrawing the blade at speed of 25-75 mm/minute from constant temperature area, quartz boat left side from constant temperature area, setting out blade from diffusion furnace at speed of 150-300 mm/minute, waiting for unloading quartz boat; the same silicon wafer batch ensuring constant temperature area of the power, constant temperature area of each single point spread gas concentration with the condition that each one silicon sheet at a speed of 25-75 mm/minute by 1 constant temperature area, ensuring each silicon wafer has same diffusion environment and same speed through constant temperature area at the same time, reducing the variance of the resistance of each silicon wafer for improving solar cell.
