IMPROVED FLEXIBLE LOW MODULUS PHOTOVOLTAIC BUILDING SHEATHING MEMBER

摘要

The present invention is premised upon -m improved photovoltaic building sheathing member ("PV device"), more particularly to a flexible low modulus photovoltaic building sheathing member, the member comprising: a flexible photovoltaic cell assembly, a body portion comprised of a body material and connected to a; peripheral edge segment of the photovoltaic cell assembly, wherein the body portion has a cross- sectional area of at least 35 mm2 within 1cm on at least 95 percent of points along the peripheral edge segment: wherein the body material comprises a composition having a modulus of 5 to 200 MPa between a temperature of -40 to 85°C, with a coefficient of thermal expansion (GTE) below 100 x10 -6/ºC, and the body portion exhibiting a warpage value of less than 15 mm.
