| description | The invention provides a manufacturing method of a solar cell, which comprises the following steps: cutting lines are defined on an initial solar cell, the cutting lines comprise a first cutting line, a second cutting line and a third cutting line, and the first cutting line and the second cutting line are respectively positioned at two ends of the third cutting line; cutting the initial solar cell with partial thickness along the first cutting line and the second cutting line to form a cutting groove; after the cutting groove is formed, heating the initial solar cell of at least partial thickness at the bottom of the third cutting line; after the initial solar cell piece with at least partial thickness at the bottom of the third cutting line is heated, the initial solar cell piece at the bottom of the third cutting line is subjected to liquid spraying cooling, so that the initial solar cell piece is cracked along the cutting groove to form a solar cell piece, and the solar cell piece is provided with a fract |
