METHOD FOR IMPROVING LIGHT TRAPPING OF SERIES CONNECTED THIN FILM SOLAR CELL DEVICES

摘要

The inventions relates to a method for improving the efficiency of converting light into electrical current of a solar module (1), said solar module (1) comprising photoelectrically inactive areas (9, 10) and photoelectrically active areas formed by a solar cell (11), characterized in that light approaching said inactive area (9, 10) is at least partially directed into said active area via at least one structural optical element (13, 14, 15).
