Abstract
The utility model discloses a crystalline silicon solar cell sheet. The crystalline silicon solar cell plate comprises a monocrystal silicon chip and positive grid lines, wherein the positive grid lines are arranged on the surface facing sun of the monocrystal silicon chip. The positive grid lines comprises two parallel main grid lines vertically arranged, multiple parallel auxiliary grid lines perpendicular to the vertical main grid lines, and a rhombic main grid line disposed in the center of the monocrystal silicon chip. The middle portion of each vertical main grid line is broken, and the broken portion of each vertical main grid line is connected to the rhombic main grid line. By employing the crystalline silicon solar cell sheet, a cover area of the monocrystal silicon chip by the main grid lines is minimized, the rate of the solar cell sheet facing sun is raised, the light efficiency of the solar cell sheet is raised, and the cost of preparing the solar cell sheet is reduce.
