Self-Cleaning, Low-Reflectivity Surface Could Improve PV Cells

Micron- and Nanometer-Scale Features Make Superhydrophobic Surface

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
