NOVELTY - The utility model claims a crystal silicon solar energy battery using graphene bus line and bus bar to increase output electric quantity, belonging to the technical field of solar energy battery application. The total of surface area of 85 silver paste lines installed on the single crystal silicon wafer surface and the root width is 2 millimeter aluminum is a narrow type bus bar of square meter of a table is 16% crystal silicon wafer is surface area, using the new manufacturing process, using 85 graphene bus line and three fine width of a 1 millimeter with a graphite core aluminum is a narrow type bus bar to replace the original silver slurry collecting line and a narrow type aluminum bus bar, a line area and surface area of the bus bars and the crystal silicon wafer square meter total ratio is descending to 9% square meter of a solar wafer light irradiation crystal silicon increase 7%, therefore a more of a quantity, at the same time, a faster at a bus speed and solar energy battery, crystal silicon solar energy battery of photoelectric conversion efficiency is expected to increase because of electric conduction velocity of graphene tune than silver, aluminum.
