<P>PROBLEM TO BE SOLVED: To achieve a solar cell protective material that imparts a satisfactory appearance to a solar cell module; and provide a solar cell module that can reduce the number of steps in a manufacturing process and also achieve weight saving by the solar cell protective material. <P>SOLUTION: A solar cell protective material includes: a polypropylene-based resin film (film a) whose elastic modulus at 23°C is 1000 MPa or more and whose crystallization start temperature is 120°C or above; and a film (film b) whose melting point is 180°C or below. The polypropylene-based resin film (film a) and the film (film b) are stacked directly one upon another with an adhesive layer interposed therebetween. <P>COPYRIGHT: (C)2013,JPO&INPIT |
