'Inverse opal' structure improves thin-film solar cells
January 14, 2014
Researchers have shown how to increase the efficiency of thin-film solar cells, a technology that could bring low-cost solar energy. The approach uses 3-D "photonic crystals" to absorb more sunlight than conventional thin-film cells.
The synthetic crystals possess a structure called an "inverse opal" to make use of and enhance properties found in the gemstones to reflect, diffract and bend incoming sunlight.Read Full Story
