Abstract
An apparatus for laminating a solar cell structure includes upper and lower housing members and an intermediate member which includes a flexible membrane. The members form upper and lower sealed chambers which can be selectively evacuated. The solar cell structure is placed between the membrane and a parallel rib structure in the lower chamber. Heater elements and reflectors between the ribs are employed for radiating heat energy to the solar cell structure during the laminating process for melting a potting material therein, while both chambers are evacuated. Then air is admitted to the upper chamber to cause the membrane to compress the laminated structure against the parallel rib support means while the laminated structure cools.
