Abstract
The utility model discloses transparent insulated layer on a solar cell. The transparent insulated layer is arranged at a light receiving surface of the solar cell through spraying or brush plating. The transparent insulated layer is arranged at the light receiving surface of the solar cell and is positioned between a main conductive gate line layer and an auxiliary conductive gate line layer. A main conductive gate line on the main conductive gate line layer is perpendicular to an auxiliary conductive gate line on the auxiliary conductive gate line layer. The thickness of the transparent insulated layer and the thickness of the auxiliary conductive gate line layer are the same and are 10 micrometers to 15 micrometers. The back side of the solar cell is also provided with the transparent insulated layer which is arranged between back surface field conductive gate lines of the back side of the solar cell, and a back surface field is an aluminum paste coating layer. Since the solar cell is provided with the transparent insulated layer, the solar cell can be protected well, the compression resistance ability of the solar cell is strengthened, the damage rate of a finished silicon solar cell in movement, transportation and storage due to force is reduced, and the service life of the product is raised.
