Self-Cleaning, Low-Reflectivity Surface Could Improve PV Cells
Micron- and Nanometer-Scale Features Make Superhydrophobic Surface
Posted March 24, 2009 | Atlanta, GA
Using two different types of chemical etching to create features at both the micron and nanometer size scales, researchers at the Georgia Institute of Technology have developed a surface treatment that could boost the light absorption of silicon photovoltaic cells in two complementary ways.
The surface treatment increases absorption both by trapping light in three-dimensional structures and by making the surfaces self-cleaning
