Solar cell sealed by glass laminations
First Claim
1. A solar cell assembly comprising first and second glass sheets which are transparent to and transmissive to solar radiation, said glass sheets being spaced apart by at least one spacer member adhesively provided at the peripheral edge portion of said glass sheets, said glass sheets and spacer member defining a cavity therebetween, one or more solar cells disposed in said cavity, said cavity further containing a filler material for embedding and potting the solar cells therein and said spacer member comprising one or more openings through which said filler material may be injected.

Abstract
One or more solar cells are sandwiched by a pair of glass laminations substantially transparent to (i.e., essentially transmissive of) the impinging light, thereby avoiding output drop which may occur due to temperature increase by passing of the impinging light therethrough. A thermoplastic or thermosetting type filler, for example, polyvinylbutyral or a silicone resin is used to fill the cavity surrounded by the glass laminations for accommodating the solar cells therein, while serving as an embedding and potting compound to provide resilient environmental protection for the solar cells. Any room temperature vulcanizing type filler may be used.
