NOVELTY - The solar cell module comprises interconnected solar cells (101) having a front side that faces the sun during normal operation and a backside opposite to the front side, a transparent cover (201) over the front sides of the solar cells, an electrical insulator (202) between the transparent cover and the front sides of the solar cells, a backsheet (205) on the backsides of the solar cells, and an encapsulant (203) bonding the solar cells, the transparent cover, the insulator and the backsheet to form a protective package. The electrical insulator has a volumetric resistance of greater than or equal to 1016 Omega cm.    USE - The solar cell module is useful in stationary applications such as rooftops or power generating stations.    ADVANTAGE - The solar cell module can be economically and simply produced with high stable and good performance thus effectively preventing polarization without making changes to the solar cells.    DETAILED DESCRIPTION - The solar cell module comprises interconnected solar cells (101) having a front side that faces the sun during normal operation and a backside opposite to the front side, a transparent cover (201) over the front sides of the solar cells, an electrical insulator (202) between the transparent cover and the front sides of the solar cells, a backsheet (205) on the backsides of the solar cells, and an encapsulant (203) bonding the solar cells, the transparent cover, the insulator and the backsheet to form a protective package. The electrical insulator has a volumetric resistance of greater than or equal to 1016 Omega cm over a temperature of 45-85 degrees C, and is configured to prevent electrical charges leaking from the front sides of the solar cells to other portions of the solar cell module through the transparent cover. The solar cells comprise back junction solar cells. The electrical insulator comprises a fluorocarbon-based polymer, is coated directly on an underside of the transparent cover, and is present between layers of the encapsulant.
