NOVELTY - A solar cell module (100) comprises: interconnected solar cells (101), each of the cells having a front side (103) that faces the sun during normal operation and a backside (104) opposite the front side; a glass cover over front sides of the solar cells; and an electrical insulator between the glass cover and the front sides of the solar cells. The electrical insulator being formed end-to-end of the solar cell module such that electrical charges are prevented from leaking from the front sides of the solar cells to a frame (102) of the solar cell module through the glass cover.    USE - As a solar cell module (claimed).    ADVANTAGE - The encapsulant protectively packages the solar cells. To prevent polarization, the insulator has resistance suitable to prevent charge from leaking from the front sides of the solar cells to other portions of the solar cell module by way of the transparent cover. The insulator may be attached (e.g. by coating) directly on an underside of the transparent cover or be a separate layer formed between layers of the encapsulant. The solar cells may be back junction solar cells.    DETAILED DESCRIPTION - A solar cell module (100) comprises: interconnected solar cells (101), each of the cells having a front side (103) that faces the sun during normal operation and a backside (104) opposite the front side; a glass cover over front sides of the solar cells; and an electrical insulator between the glass cover and the front sides of the solar cells. The electrical insulator being formed end-to-end of the solar cell module such that electrical charges are prevented from leaking from the front sides of the solar cells to a frame (102) of the solar cell module through the glass cover. The solar cells comprise back junction solar cells. The electrical insulator comprises a fluorocarbon; and is coated directly on an underside of the glass cover. The electrical insulator is coated on an underside of the glass cover. The solar cell module further comprises: a backsheet on backsides of the solar cells; and an encapsulant bonding the solar cells, the transparent cover, the electrical insulator, and the backsheet to form a protective package. The electrical insulator has a volumetric resistance greater than or equal to 1016 Omega cm over a temperature range of 45-85 degrees C.
