(US5743970-A)      Photovoltaic module (1) comprises a photovoltaic panel (2) having front and back sides and edges forming a perimeter, and at least one photovoltaic cell which converts radiation, incident on the front of the panel, to electrical energy. The panel is encapsulated in a non-reacted injection moulded polymeric material (3) which forms an environmental seal for the module.    USE -   Used to produce photovoltaic devices which may form useful structures e.g. shingles, blocks, cases or boxes.    ADVANTAGE -   The process is adaptable, and does not require the use of precursors, extenders, catalysts and blowing agents used in reaction-injection-moulding, these chemicals being expensive and toxic.
