NOVELTY - A photovoltaic article (100) comprises photovoltaic cell assembly (110) and body portion (120) connected to at least one edge of the cell assembly, where the body portion contains composition having melt flow rate of at least 5 to not greater than 100 g/10 minutes, coefficient of linear thermal expansion (CLTE) which is within factor of 20 of the CLTE of the cell assembly, flexural modulus of at least 500 to greater than or equal to 1500 MPa, tensile elongation at break of at least 100% of original length, relative temperature index (RTI) electrical and RTI mechanical strength rating, each of which is at least 85 degrees C.    USE - As a photovoltaic article (claimed), such as building integrated photovoltaics. Also used as roofing shingle or other building fascia.    ADVANTAGE - The composition has after mold shrinkage of less than 2; melt flow rate of at least 5 g/10 minutes to not greater than 100 g/10 minutes; flexural modulus of at least 500 MPa to greater than or equal to 1500 MPa; tensile elongation at break of at least 100% of original length; and relative temperature index (RTI) electrical and an RTI mechanical strength rating, each of which is at least 85 degrees C. The composition enables robust function over a period of years when the photovoltaic device is mounted on the exterior of a building.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a composition (C1) comprising polypropylene and/or a copolymer of propylene and ethylene (30-80 wt.%) which has a melt flow rate of 5-100 g/10 minutes; polyethylene, and/or ethylene/ alpha -olefin copolymer (5-30 wt.%) which has a melt flow index melt index of 1-100 g/10 minutes and density of at least 0.85 g/cm3 to less than 0.97; and an inorganic fire resistant material (10-50 wt.%).
