Light trapping texturing
Here is a machine developed by 1366 Technologies which it is marketing to solar manufacturers. The machine places a polymer surface on a silicon wafer during cell manufacturing. The machine creates a textured surface that cuts down on reflectivity, increasing the amount of light the cell can capture and convert to electricity.
