<P>PROBLEM TO BE SOLVED: To provide an intermediate layer for a solar cell module which can increase its volume resistivity and thereby enhance power generating efficiency of a solar cell module using the intermediate layer, and a solar cell module using the intermediate layer for the same. <P>SOLUTION: An intermediate layer 2 for a solar cell module contains polyvinyl acetal resin and plasticizer. The total degree of acetalization and acetylation of the polyvinyl acetal resin is more than 70 mol%, and the degree of acetylation of the polyvinyl acetal resin is more than 5 mol%. The solar cell module 1 has the intermediate layer 2 for the solar cell module, and photoelectric conversion elements 5 which are laminated on the surface of or buried in the intermediate layer 2 for the solar cell module. <P>COPYRIGHT: (C)2012,JPO&INPIT |
