<P>PROBLEM TO BE SOLVED: To provide a solar energy utilizing device equipped with a water and oil repellent and antifouling coat having improved durability such as wear resistance. <P>SOLUTION: The water and oil repellent and antifouling coat formed on the surface of a light receiving face side glass plate is a composite film which contains a long chain material using fluorocarbon groups and hydrocarbon groups as main components, a short chain material using fluorocarbon groups, hydrocarbon groups and silyl groups as main components, and a material using siloxane groups as main components. In the manufacturing processes for the coat, entirely no hydrochloric acid is produced because of no use of alkoxysilane. <P>COPYRIGHT: (C)2009,JPO&INPIT |
