Light-trapping structures for thin-film solar cells

We develop broadband light-trapping structures based on regular arrays of nanostructures and microstructures often referred in the modern literature as metamaterials. Our suggested light-trapping structures offer the gain in the optical efficiency of thin-film solar cells of several types without damaging their operational characteristics. These types of photovoltaic devices include thin-film solar cells based on amorphous silicon, organic and perovskite materials.
