A solar cell and a manufacturing method of the solar cell are provided. The solar cell includes a silicon substrate, the silicon substrate is deposited with a plurality of fine-grids, the plurality of fine-grids have ohmic contact with the silicon substrate; a plurality of main-grids are disposed on the silicon substrate; the plurality of main-grids intersect and electrically contact with the plurality of fine-grids; at least a part of the plurality of main-grids is formed by sintering an electrode slurry. The plurality of fine-grids and the plurality of main-grids are formed by a combination of a high temperature metallization (sintering) and a low temperature metallization (depositing), to overcome a high cost by using screen printing of silver slurry, in addition, due to the plurality of fine-grids having ohmic contact with the silicon substrate, the solar cell has advantages of small contact resistance and high current collection efficiency.
