Description

technical field

[0001] The present invention relates to a solar cell module (back contact solar cell module) using a back contact solar cell, and more particularly to a material used in the back contact solar cell module.

[0002] This application claims priority based on Japanese Patent Application No. 2012-080915 filed on March 30, 2012, and Japanese Patent Application No. 2012-258021 filed on November 26, 2012. Here, The content thereof is cited in this application. Background technique

[0003] A solar cell constitutes the heart of a photovoltaic power generation system that directly converts the energy of sunlight into electricity, and is made of semiconductors.

[0004] In addition, in the use of solar cells, they are not directly used in the original state of the solar cell elements (cells). In order to protect the solar cell elements for a long time, they are usually packaged in various packaging components to be connected in series or in parallel. A module (unit) ...
