<P>PROBLEM TO BE SOLVED: To provide a protective sheet for a photovoltaic power generation module, which has durability, strength, and flexibility to withstand severe weather environments surrounding a photovoltaic power generation module and exhibits excellent gas barrier properties, steam barrier properties, heat resistance, flame retardancy, electrical insulating properties, low thermal expansion and the like. <P>SOLUTION: The protective sheet for a photovoltaic power generation module comprises a clay film layer, wherein a composition weight ratio of a clay component is 80% or more and a thickness is 1-1,000 μm. In the protective sheet for a photovoltaic power generation module, a hydrophobic resin film layer, wherein a water contact angle is 60 degrees or more and a thickness is 1-1,000 μm, may be layered on the clay film layer. <P>COPYRIGHT: (C)2010,JPO&INPIT |
