Abstract
Photocell modules wherein one or more photocells are encapsulated within a thermoplastic polymeric pottant between the layers of a rigid or flexible laminate. The pottant is a graft copolymer of (a) at least one addition polymerizable backbone monomer having a glass transition temperature (T.sub.g) of less than 0.degree., (b) at least one addition polymerizable backbone monomer having a T.sub.g of 50.degree.-150.degree. C., and (c) a poly (vinyl aromatic) addition polymerizable macromonomer of 3,000-50,000 molecular weight having a T.sub.g of at least 30.degree. C. The pottant is highly light-transmissive, electrically insulating and provides excellent protection for the photocells and circuitry at low cost.
