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 (Tg) of less than 0 DEG , (b) at least one addition polymerizable backbone monomer having a Tg of 50 DEG -150 DEG C., and (c) a poly (vinyl aromatic) addition polymerizable macromonomer of 3,000-50,000 molecular weight having a Tg of at least 30 DEG C. The pottant is highly light-transmissive, electrically insulating and provides excellent protection for the photocells and circuitry at low cost.
