Abstract
A solar cell module includes solar cells encapsulated in a high resistivity encapsulant. A protective package is created by forming together the high resistivity encapsulant, the solar cells, a transparent top cover and a backsheet. The protective package is mounted on a frame that is electrically isolated from the solar cells. The protective package may be created by lamination. The transparent top cover may comprise glass or a high resistivity material.
Claims18
A method of fabricating a solar cell module, the method comprising:
- placing a first sheet of encapsulant on front sides of a plurality of solar cells, the first sheet of encapsulant having a volumetric resistance that is equal to or greater than 1016 Ωcm;
- placing a second sheet of encapsulant on backsides of the plurality of solar cells;
- and
- encapsulating the plurality of solar cells in a high resistivity encapsulant by heating together the first sheet of encapsulant and the second sheet of encapsulant.

A solar cell module comprising:
- a plurality of solar cells encapsulated in a high resistivity encapsulant, the high resistivity encapsulant having a volume specific resistance equal to or greater than 1016 Ωcm over a normal operating temperature range of 45 to 85° C., the high resistivity encapsulant being configured to prevent polarization by preventing charge from leaking from front sides of the plurality of solar cells;
- a transparent top cover over the plurality of solar cells;
- a backsheet under the plurality of solar cells;
- and
- a frame framing the plurality of solar cells, the high resistivity encapsulant, the transparent top cover, and the backsheet, the solar cells being electrically isolated from the frame.
