ENVELOPE MATERIAL SHEET FOR SOLAR CELL MODULE AND SOLAR CELL MODULE INCLUDING SAME

摘要

The envelope material sheet for a solar cell module of the present invention has a configuration wherein a plurality of hemispherical concave parts whose sizes are different from one another are formed on the surface of one or both sides of a soft transparent film, wherein pressure generated in the process of combining the envelope material sheet and a solar battery cell is dispersed to prevent damage to the solar battery cell and bubble generation may be suppressed by allowing air to escape easily.
